aoamy cars idle rpm is making problems..it drops from 800 to 600 whenever i turn a/c on and at the same time turn the steering wheel ..this behavior is both on cng and petrol..throttle body cleaned,tappets adjusted,kit serviced but of no use one mechanic increased the rpm manually but when i put the car in gear it drops down again on a/c.. the car is vti prosmatec 2002..
Checkout VSS/Vehicle speed sensor.Secondly if its faulty should also drop RPM on cold start
when the car is cold then its rpm is fine stars from 1100 and comes to 800 slowly...and one thing to mention on petrol some times its rpm drops not all the times and does not drop very badly as it does on cng..
some one mentioned enercon G10, bela road is good.
my personal experience with rehman cng, peshawar road(near chohar chawk) was good.
On steering turn rpm does fall sometimes.....check the pulse wire and auto choke for AC. (Not sure does Auto Choke exists in this model).
also might be coz of faulty advancer?? mine was giving this problem after car wash
the same thing happened with me.. i tried almost all the possible solution but none worked.. my mechanic installed a manual idle that got the problem fixed.. now almost more then a year every thing is fine...
thanks for ur reply friends..today i m going to my mechanic..he will open cng kit plus all the electronics with wiring...if needed i will change my advancer too..lets hope for the best =)
