rough idle, running rich, smoke help
working on my buddys 89 lx it idles like it has a miss but you can smell fuel really strong and it smokes whitish blue. we've tested each plug and wire. we pulled codes 41 and 91 (hego lean both sides) if you unplug the maf sensor the cars idle doesn't change, recently replaced the tfi and full tune up

Unplugging the MAF should just about kill the car, so I'd start there. The smoke is probably not related, and is more than likely a mechanical issue with valve seals or rings.

theres no way fuel would drip from the exhaust. the system is way too hot. that fuel would be vaporized before it hit the mufflers, unless you're literally dumping more fuel into the exhaust than you are burning.

That sounds like a head gasket . the reason it smells like gasoline is because of the vapors that are not being ignited due to the antifreeze dousing the cylinder.

When I turn my key over the fuel pump kicks on like usual but when I get the car started the fuel pump is loud as hell I ran outta gas the other day and I jus got more gas in it and that's when the smoke started I thought it was just dirt in one of my injectors but then it start either not starting or starting hard and idling rough
