Hi Everybody,
I live in Byron Bay and own a VL Station Wagon, made in May 87, a normal fuel-injected 6 cylinder. Overtaking some trucks doing about 130kph back in early March, I suddenly lost power, all my warning lights came on, and I coasted to the side of the freeway. Such were the symptoms that I presumed I had broken my timing belt. After stripping the motor to find the timing belt was fine, I later sourced the car's onboard computer, and replaced the crank angle sensor. The old girl started first go, and ran beautifully, until it reached normal operating temperature - and then started popping and backfiring as though a fuel feed was the problem. I have since had it at various mechanics, and had a new coil fitted, but the problem persists. I have now replaced the fuel pump down near the tank, the fuel filter, and cleaned all contacts on things such as the air flow meter, but still no joy. I am at my wits and wallet's end. The car has a straight rust free body and I am loath to give up on her, but where can I turn next? Any suggestions? Thank You! regards, Sarge.

Gosh that's a sad storey there buddy :( poor ol' girl. Could be a number of things, like you said you've replaced a lot. Only things I could suggest is flush the cooling system,, torque converter is stuffed or your gear box?? Would be so nice to have a straight answer and not have to stuff around working on her and dishing out unessesary cash :( I hope you can get her fixed, best of luck.

Hey Sarge was the parts you replaced second hand or new?
Don't give up champ?

Does the temp go up high when it starts back fireing
