Hi all, I have a '97 80 series with a 1FZ-FE engine. It has been modified to run duel fuel. (LPG-Petrol) It starts and runs fine except for a misfire that appears at around 2000 to 2400 RPM. It usually happens when its just cruising and not really under much load. If I accelerate hard, it revs out fine with the misfire gone.
I'm feeling that it could be either the spark plug leads, the spark plugs themselves or the injectors. Any advice on any tests I can perform to try and diagnose this misfire, so I'm not just throwing cash at all new parts, would be greatly appreciated.
Cheers
