I replaced the maf coil packs and plugs haven't checked anything else I'll do a compression and leak test on it.There is a misfire sticky floating around you can check. It gives a lot of possibilities. I'll list a simple few things to check.
Compression and leak down, dirty or bad maf sensor, idle control valve, vacuum leaks, bad plugs, bad coils.
Besides the plugs and coils have you checked anything?
OK will do thanks for the advice
