Aoa, the problem is my car vibrates when i take it above 100mph..i noticed it as i was diving it on motorway from lhr to isl yesterday....i got the brakes serviced and disc pads changed few months back....so i wanted to know is this wheel balancing problem? or some thing else.....
Also recently i got the fuel injector changed as well as ignition switch.....my car is very smooth now the missing all gone but still it heats up gradually....the switch when opened was burnt inside...the 50A side of it....a few days before changing the switch the fuse which controls back lights and meter lights was also burnt...i changed it and then the switch and few nights later the front lights stopped working ....so i checked it up from some random guy and he simply touched the front lights with his tester and they started working again.....i think some thing is putting load on the switch but i cant put my hand on what is.....any help?

CHange your engine mounts,this is the probable cause for vibration if they are too old

Better get your car check with a good woo electrician

aoa
hope everybody is in good health. consulting this forum after a long time.
I m having really troubled time since I bought Daewoo last year n now at a point where I m almost fed up of this. really need help from u guys, specially test driver.
problem with my car is engine vibration that mechanics think is coz of missing n due to missing car millage is very bad. but they dont know y car is missing. i went to lahore from isb via motorway n car did 370km in full tank at 90km speed n without AC. I went to a daewoo specialist there he checked n changed plugs n did some tuning but still car is doing 7km/l.
firstly different mechanics said that engine is vibrating due to crank shaft as crank shaft is worn out n engine needs an overhaul, after few months they changed there mind n said car has blow so rings need a change thats y engine is vibrating, then after a few months now different mechanics said that vibration n missing is due to head n head need repair. no mechanic assured me that vibration n missing will vanish after head or ring job so i did not go for that.
now that mechanic is saying that rings r weak but no need to change this vibration n missing is due to tappets n cam is chinese n faulty n due to this cam tappets r not working fine n cam needs replacement after that engine will b smooth n he is giving guarantee that fault will b rectified after cam change, n mileage is low coz of missing n till the time missing is there there is no solution to mileage n vibration.
Should I go for the cam job @testdriver.
some history
upon reaching lahore I checked the error codes n 15, 21 35, 41,54 n some more codes apeared one was about timing i dont remember what that code was. I knew my cars IACV was faulty n no IACV was working from kabli parts in pindi so I went to Korea Auto he demanded 3k for new korean IACV n 1700 for working kabli but upon installing kabli none was working. I went to mechanic he checked his kabli IACV n that was also not working. he changed TPS (courtesy Tahir he changed my working TPS few months back n installed a faulty) IACV started working n all codes were gone. changed plugs old ones had reddish brown tips but oil at the threads. radiator is in bad condition n fan is direct. I noticed that when car is tuned with fan unpluged with minimum vibration n when fan is pluged in engine rpm drop n again needs tuning to minimize vibration n headlights also have effect on engine rpm when turned on so tunning that engine is really difficult so mechanics increase timing n co n rpm to keep engine stable resulting in heavy fuel consumption. I also noticed that injector is throwing lot more fuel like shower than other cars. car really behave differently on cold n hot (if adjusted when car is cold rpm really increase when hot n vice versa). one last thing tappets r making very heavy noise like diesel engine. once i felt tappet noise reduced n car performing very good pickup start n noise when i my self adjusted rpms n timming but next morning driver started the car n everything went erratic n car is just satnding for the last weak as i cant figure out how to solve the issues. ecm wiring was checked last month n coil also.
sorry for a long long post waiting for the help.

aoa... i wanted to know about daewoo fuse box... n the fuses we use in them.. i read there function n i also read if we apply a fuse of different ampere then required at that place it can cause short circuit.. but in my woo a few fuses r damaged so they r given alrenate current from other working fuses.. i wanted to to know can i use a 30A fuse at the place of 20 A.. due to this alternate current route... i replaced a Fuses which were melted n. Also changed the old ones... i think the current is overloading on the circuit.. using high ampere fuses can protect the system??? Test driver would u like to comment please...

@guybwp

always use proper Ampere Fuse for the protection of circuit.
30A fuse mean that this fuse will blow if more than 30 A current will pass from this circuit due to shortage. if you replace with 20 Amp fuse it may blow on normal operating conditions.

now another story:
if you place 20 amp fuse instead of 10 amp this is too bad, because this circuit is designed to operate on 10 ampere and more than 10 amp may damage the inline circuit but you have placed 20 amp fuse, mean rating of circuit is 10 amp if there is current of 15 amp it may damage the circuit but you have place 20 amp fuse which will not blow and its corresponding circuit may blow.
fuse box detail is as below

ok but my another question is in case of old cars esp daewoo the wiring is damaged to such an extent that the fuse timbles on fuse box dont work so alternate route in provided to that circuit from near by working ones....so what shall we do then? use the same ampere fuses..wouldnt this alternate linkage will put more load on that single fuse?

[guybwp]

i was replacing worn out fuses today n i observed 3 or more fuses in the process of melting...im not sure where the excess current in coming from coz recently i had to change the ignition switch as well coz it was burnt inside ...it worked when cold but after heating up it wouldnot....

[vc_engineer]

first try to use proper fuse, if fuse burns then you may use higher rating fuse.

one more thing , fuse from ordinary Auto shop are not good (Rs. 10) fuse are not good.

try to find genuine (kabli) fuse from Kabaria, in Rawalpindi Ahata mithoo khan etc.

@testdriver
AOA Adnan Brother,
Sorry for getting out of touch for long time, i was abroad for some time.

my racer missing / jerking (on petrol) after driving 3 to 4 km , do not pick acceleration and engine turns off. i start again, it starts in half self and drive 1 km and again same problem. if i switch to CNG on first jerk it continues to run smoothly ( i have little CNG filled from Haripur)

later on i realized that if I turn OFF/ON petrol switch (neutral position then again on petrol) on first jerk ( even do not shift to CNG) and turn on again jerks finish for about 1 km then on next jerk i turn off petrol/injector it solves problem for a while. I realized that it is fuel pump or inline fuel filter problem. i checked filter it was ok then i replaced the fuel pump.
by replacing fuel pump solve the problem but after driving almost 50 km little jerks whenever i switch the gear, pick has reduced as well.

i went to Khalid, scanned all the sensors , all sensors are working fine , everything was ok on idle (car standing position)

but again when i moved out of I-9 pick still reduced jerks during gear shift.

what may be the problem?

is it injector? or some other problem? i have not checked fuel pump pressure by proper gauge but visually it is very good pressure.

guide me in this regard.

khalid retarded timing a little bit now timing is around 15

thanks

@guybwp
local / desi fuse melts, try to buy genuine fuses from old parts shops.

Guys my car is getting a repaint.My original bumper are in miserable condition.Any vendor selling bumpers or stocking fantasy one's at reasonable quote?

This is my first post on this forum
I have learnt alot from this forum.
Now I have a problem that I m unable to resolve
My woo cieilo runs smootly with,out ac and blower
As I switch on ac or blower I start jerking and becomes very heavy
First it was happening on head lights then I fed headlights directly from battery
I have also tried by feding ac and blower( run on high speed) but there is no improvement.
I m in jhang. Here is no any Daewoo mechanic
Any one who had this should know what can be the solution
Or testdrive may guide me what to do

Thankx in advance

it seems that your car electrical system is not good, check voltage of fuel pump before and after blower starts. If voltage at fuel pump is low then definitely fuel pump is not operating on its required voltage resulting low fuel pressure.
you may attach a relay with fuel pump/blower or get the wiring checked from you electrician.

Jamroz Khan 0331-5119311 IJ Principal Road Rawalpindi near old Tool Plaza have lot of bumpers these days you may check from there

@jazz82
when did you change engine oil? tappet sound may be due to engine oil quality and low in quantity.
does any error code flashes as you have faulty TPS or you changed TPS again?
How you adjusted timing?

[vc_engineer]

@jazz82
can you share names of workshops/ mechanics you visited recently, who told you about cam and who about rings. are all of mechanics daewoo experts or you also visited to other mechanics as well ?

i have already attached relay on blower
i have checked voltage on fuel pump it is 7.6 to 7.8 with ac, blower and head light and without this load voltage is same for the pump that is 7.6 to 7.8.
what is normal voltage level for fuel pump?

[vc_engineer]

Detach grip of fuel pump then measure...it should be 12 volts
