1999 isuzu rodeo will not stop misfiring, changed alot on it and now i need help
i have a 1999 isuzu rodeo and i have changed all that i know to stop this misfire. it will
miss under a load and just driving highway speeds, it also backfires sometimes. i
have changed the timing belt tensioner pully all 4 o2 sensors egr valve and cleaned it,
replaced the injector o rings, fuel pressure regulator, all spark plugs and all coil packs,
fuel filter and fuel pump. we also just did a compression test on it and the psi was all
pretty similar, the lowest was 110 and highest was 150. i just need help on what to do
next because i cant handle it anymore. thanks
