^^i guess i logged off before i red the pm.and yeah the pcv is at the left back side of the tappet cover.
isnt PCV suppose to emanate from crankcase below?
The red one is PCV, you need to remove the pipe by opening its clip, then remove the PCV with 14 number spanner, then clean it with carb cleaner and check its function by shaking it, if something knocked inside then it is functioning rightly.
@Horse_rider. Sparkplugs cables replaced but still backfire problem with 0% improvement. airfilter box's lower clips are broken. Does the CNG workshop that u told me before on peshawar road opposite to allied bank ( i forget the name of the shop) has solution to this issue? backfire only happens on cng and alot. no issues on petrol.
Rehman CNG workshop is the name. and you should repair or replace the air filter box, spark plugs should also be cleaned and checked for proper operation, for backfire issue I am not an expert in this area, hope some other member will help you. go to that workshop and tell him the problem, He will surely solve it by inspecting the related parts.
thanx....but shouldnt PCV valve be linked down with the crank-case ???or...whats the pipe shown by yellow arrow.??
My car start missing on PETROL only.. When I gave accelator it behave like plug not working.. It gives very poor pick and as it cross 20kmhp speed.. car runs fine.. no missing problem.. Car plugs are new NGK brand.. As I opened the car bonnet and touch the electric wires.. Car stoped missing.. but when I drive it strats missing again.. Any suggestions?
@Horse_Rider i went to an efi cng expert yesterday and he told me that air filter box should be replaced as car is getting air and this is the cause of backfire. i replaced air filter box with a new one. car behaved normal, cng tuned and on my first test run, soon after 20-30 feet heard a blast and air filter was again broken by backfire he then unpluged each HT Cable from the ignition coil and told me that tappet adjustment is not proper as starting 1st two plugs from left (if you stand facing to the car) are getting the spark and firing but due to un-proper tappet adjustment they aren't burning the fuel and causing backfire. it was too late and machenics were closed so i couldn't move further but to drive home back on petrol. i am feeling that the cng guy was scrap and just putting blame on others. please anyone guide me i am in great trouble.
Dear @atifnaeemmalik dont say that mechanic scrap ... they are like doctors which first gave u medicine which is usually given but then if it doesnot works then they workout more ... so my suggestion is to go that mechanic again and ask him to do it right .... or go that one which u feel is the most experienced one that may have gone through such situations before
probably some electric contact issue, clean all the grips and you are good to go....
the PCV is the red one, thats for sure, and I don't remember the yellow one.
Check the injector plugs, one of these will be loose or disconnected, if fine on CNG. If missing is on CNG also then plugs problem. otherwise injector is disconnected.
Car runs fine on CNG and on PETROL it start missing on low speed only, but on high speed it behave normal..
@faizanalicheck the red circle in the pic attached and clean the contact in this fig...it happened to my santro once too but was solved mingling with this contact....
I have bought Air filter cover, and Steering rubber boots for Rs. 350/- pair, and Air filter cover for Rs. 450/- the rates are okay??.. some members have changed their air filter covers thats why I am asking. Secondly the paint code of Black colour santro is required if anybody knows. I want to paint the left fender of car with a matching colour. thanks.
@rizkhan yes you got it right about the function but the position is not usually there which you think like.
@iamadee are you talking about coil connectors?
yeah i guess so...
Car plug wires were week and changed to ORANGE color plug wires as it start giving back fire and air filter box use to open after back fire / Also one injectror not working properly.. It require cleaning .. BUT where to go for INJECTOR Cleaning in LAHORE? I have ask ABID Computrise tunning wala.. He is not offering such service..
There is a workshop in model town near gourmet bakery, I have heard they are offering injectors cleaning services, I don't exactly remember its name i guess it was magic motors....
