@Xulfiqar any clue about my issue? also downshift to first while braking is very harsh is that due to TPS?

Yes - wrong signal from TPS will cause all sorts of stupid shifts in the gearbox. Connect a good tool to the car and force it to learn its "aukaat" aka learn idle.

@xulfiqar i adjusted crank pulley at tdc looking through v groove n arrow n aligned the tdc mark. but at cam 7 O mark is little mis aligned at tdc. car is consuming fuel alot after engine swap from d15b2 to ď14z2(92hp d15 90hp d14z2) but i didnt swap ecu coz d15b2 ecu is simple fuel injection (sfi) ecu and stock d14z2 is also using the same ecu p3s ( i dnt knw map difference).

the sensor that my ecu dont have

no o2 ,cyp ,knock,crank, sensor and no catalyst and coil ignition

i mean its very basic fuel injection ecu i didnt feel black smoke too in exhaust ... IMA is set to 2.33V

kindly mre dard ki dawa kro

consuming petrol alot but no sign of carbon on tail

Bhai what do you think of mechanics slightly oiling the belts to reduce that certain noise - not the squeal sound exactly but that other kind of noise.

got it
about the Permatex red one that the only thing they had at the moment (originally went to buy caliper grease) plus its been over a month and i dont think those stubern people while change it so can i still use it ?
thanks for the detailed reply

Permatex claim its OK to use on transmission sumps - I have personally never used it though. Please do not let the mechanic smudge it around with his fingers. And if you are going to use this then do not use any other gasket on the sump.

Apply it with the provided nozzle, cut it so you can lay down a 3mm bead. Apply the bead in a way that it is continuous all the way and going inwards from the bolt holes, once you are done with the bead, then make small semi circles around the bolt holes to join them to the main one piece bead.

Ensure that the surface was just cleaned with acetone right before you apply the bead Similarly the transmission sealing surface should be cleaned and wiped down with acetone so that there are no contaminants on it.

You only have ONE chance to set the sump on the transmission - that is why I advised you to make 2 guide bolts. It goes in straight without fiddling and start at least 2 bolts, install all other bolts and tighten down - leave alone for about 2 hours then fill ATF. This material will fully cure after 24 hours.

please ask for the narcotic the mechanic is using.

please ask for the narcotic the mechanic is using.

Hahah i am afraid i can't [emoji14]

From the above post, the part where you said apply the bead such a way that it is inwards from the bolts, you mean we should apply the bead close to - not exactly on the - boundary of the sump and should make our way below the bolts holes and then circle the bead on uper half portion of bolt hole. Right?

Secondly, what should be done for that belt noise by the way I noticed it goes away if we through a slight amount of water on belt but comes back after 5 or so minutes (i guess when the water dries up that noise comes back). What's proper remedy for it?

[Xulfiqar]

like this.

please excuse the crude stupid looking bead - my problem was that the sealer I used is GM engine sealant which is really really thick - it requires me to use a caulking gun which decided to act silly at the time. I also did not do the outer side of the bolt holes - I did not need to in this case and application.

BUT

Zero leaks - not even a seep.

Got it.
Your take on second half of my last post ?

clean the belt and pulleys and check for stiff moving pulleys too. If the belt is worn out replace it with a good quality item.

I too suspected that so i pulled off the belts and inspected them for any dis-aligned and bad rubber portion there wasn't any. Checked the pullys for any unnecessary play in them they were firm in their place then pulled the AC belt off repeated the procedure and spinned the AC pully it too didn't had any play and was spinning firmly and without any hesitation. Did the belts and again the noise was there
Any thing i am missing?

And yes the noise increases when AC clutch kicks in.

Well went to Honda and asked to hand over hds . They were generous enough to let me operate it. I adjusted tps to .49 but tps % and relative tp was above 5. After reset from software nothing happened. Could not find idle learn. Then we adjusted tps so that both values become 0.00 which yielded 0.2 v on tps. At this car is working smooth and everything seems to be fine.

@xulfiqar
AOA hope you are doing fine.

I have a slight problem i was hoping you could help me.

i have CG125 2011, recently had it's headwork done

Now i am facing an issue which existed even before this work. Upon release of throttle at higher RPM there is a popping sound from exhaust. The mechanic corrected it by making the mixture rich from the idle screw,and the popping got reduced a bit but now there is another problem. At high speeds when i let go of the throttle and than twist it again there is a hesitation or deadspot, it does a bit of missing. Both there problem occur at high speed from 0-60 it is fine and smooth.Can you tell me plz if this is specifically a carb problem or is there another issue.
Here are some facts
1)New spark plug
2) no air leak checked
3)CDI unit and coil were replaced to for experimentation but the problem remained the same.
4) Jets of carb were changed and the jet needle in the C-clip is in the middle as it is suppose to be

Do i need a new carb ? Plz do reply. Thanks

cant figure out why car is running rich. air filter is new no oxygen sensor cleaned throttle body too. just swap d15bw to d14z2. @xulfiqar

By this look I think Could be. Take pictures from tip. These seems to be deposits of additives. Tell us what was swapped ? Head assembly? Or complete engine ? Did you swap ECU? Wiring ? Which injectors are you using are you sure they are the ones that came with your ride? I have 4 good injectors from a d15 which were cleaned by ultrasonic machine and flow tested may be you can try those. I'll bring when I come to dad. Maybe on Monday but not sure

Accelerator paddle of civic 99 vti automatic struck every time when car is parked situation Then I have to press the paddle to full and with little bit power and paddle will perform its function perfectly afterwards. Then if car is stop at signal or parked for sometime, gas paddle struck again and then press the full paddle with little power so that paddle can be pressed.

Visit to mechanic, he checked and said accelerator cable will change and gas paddle will be service. I asked him to do, he changed the accelerator cable and service the paddle by opening it, washed with petrol and apply grease to upper part of paddle especially on upper part containing spring.

But problem is not resolve still same thing happening every time when car is parked at signal and in garage. This really annoying now.

Can you Please tell me why is this and how to resolve the problem completely.

It's your throttle body butterfly which is getting stuck.

Okay But Throttle body serviced recently but problem persists. Is cable quality causing this issue?
