Categories: Electrics, ECU, Warnings & Lights
Hi guys
Looking for some help. I have an astra 55 1.6.i lpg converted this about 2 yrs ago, lastyear when lpg was serviced the car began to misfire, but when you restartthe car it fixs itself.
In the morning when i drive the car and go over 40mpg the engine management light flashes and misfires. I just restart it and it works fine, some time i have to do that afew times...
I have changes the: egr valve, maf sensor, lamda 1 +2, crankshaft sensor, coolen temp sensor, cleaned the throttle body. Only things i change now are ecu or injectors, but would injectors reset themselves when car restarts?
Thanks

the usual things apply a fault code read is a good start, as you mention the fault has only occurred since the lpg service i would suggest it could be this thats at fault such as a faulty emulator.
Speak to your lpg specialist again, depending on what system you have fitted they should be able to connect to the computor and reset the parameters if needs be

Hi thanks for that

The code always reads cylinder 2 misfire. Once when i read it it said all 4 were misfiring. The guy who did the lpg has buggered of to australia, i spoke to someone who does lpg and they said as the problem comes on when on petrol and lpg it wd be an 1% chance of lpg error.
Would the injectors reset when i restart the car...?
