missing in drive

[bangers]

hi. have a vt v6 that only misses while driving. while in idle there is no miss but when you start to drive it misses. mechaninc 'thinks' it's an injector but that should miss in idle too!? maybe afm? or o2 sensor? should i reset the ecu? if so how do i do it?

thanks for any info!!!

If it's missing under load - I'd be sus on the leads or plugs first. Or even a coil before I looked at the injectors.

If the injector is clogged put a tube of injector cleaner though it.

A bad lead is the most likely culprit, but could also be the other things mentioned above.

plugs and leads just replaced. coils swapped around. just found the air filter clogged. cleaning that now. see how that goes but just in case may it be the o2 sensor or afm?

well cleaning the filter didn't help. it misses more and more under load. will have to try injector cleaner tomorrow.
