Multi cylinder failure and a funky smell from the tailpipe.

Car: Acura, TL, 2000, 3.2 - Back to Fix-It - Acura TL Repair Manuals

Q.check engine light is on says multi cylinder failure and a funky smell from the tailpipe.

I already checked/done: changed plugs

Answer Usually this is caused by a bad coil. Try unplugging the coils one at a time and see if one causes the engine to slow down less than the other's. Then move that coil to another position and retry. These will say multiple miss fire even if only one is actually missing. Start here and let me know what happens then we can go from there to narrow it down.
