salam,guys i am facing this problem that after i switch off my car engine it gives me 3 and 4 jerks
is it mehru ?
sorry i forgot to mention my car model it is 87 oval 2 door charade with petrol engine
If this happen's only on PETROL Mode, then it's the Problem Of "IDLE SOLENOID", normally mechanic called it "SLOW SWITCH".used slow switch may be around 300 - 500 Rs.
Bye
Very advanced timing due to cng can led to detonation and jerks as you are explaining.
