1995 Buick Skylark problems. Check oil light on

1995 BUICK SKYLARK

Ok I posted before but not real answers, here is what happened every once in awhile when taking off from a stop the car would sputter or it seemed too then it would be fine. It didnt do this all the time just once and a while. I went to work and started it and now it does it all the time. I replaced Coils, Ignition Module, spark plugs. Still does it. I do notice the check oil light is on now tho. It had a recent oil change also.

so any ideas?

You need to be concern with the oil pressure the light is coming On. Could mean bad oil pump/bearings/clogged-up pick up screen-sludged crankcase.

Install an oil pressure gauge and confirm the oil pressure.

As for the sputter-could be an oxygen sensor, throttle positioning sensor, MAF/MAP sensor or fuel pressure problem.

Could a bad oil pressure switch be causing it? I have heard it could cause this?

No check engine light or codes are on, so I dont think my O2 is bad.

You need to do an oil pressure check with a gauge to confirm normal pressure, if it checks out-replace the OSU. Who knows could be a wiring problem too. Investigate thoroughly before you draw conclusions.
