What causes the engine to miss fire on #2 cylinder?


If you shoot me your year I might have the info you need. And - depending on your year - the 94ish years had TWO coil packs for the 4 cylinder - 8 plug wires basically. When any of the leads of either of those coil packs goes out - youre going to experience a miss condition. If it's the v6 - you've got a cam sensor that can cause that type of action - and have you checked your throttle positioning sensor? If that goes out - the ecu will get mixed signals and can act like that as well. If you can tell me the year I'll see if I got the info you need. All the best.

1992 Buick regal running with miss


I would do a compression test to see if all cylinders are good, and no internal mechanical damage has occurred.
If compression is good, check for possible intake manifold leak that especially affects the right bank- the bank with 1, 3, and 5 cylinders.
No way I can think of that spark would be different on the right bank, so it could be wrong air/fuel mixture for that side, or possible loss of compression that is causing the misfires.

Is the check engine light on.. If so lets get the codes and go from there. Autozone provide this as a free sevrice. and they also rent the tool . It could be many things mass air flow sensor ,, Throttle body..Good luck!!!

Engine light on, bad fuel milage


You didn't mention if you replaced the mass air flow sensor, if the tech got that code, it needs replacing, if you haven't alresdy done so.
