-change the oil if the cpi was infact leaking; gas in oil = damage to bearings in the engine. -while swaping the cpi, it would be a good time to do a tuneup, if not already done, since u have the upper plenum off. -check the O2 sensors. if they are bad, they can cause the ECM to flood the engine and it will miss like crazy. -as for the check engine light, use a scanner to pull the codes and let us know what they are. im sure im missing something so someone will correct me, lol. hope i have been of some help.

Re: 95 blazer missing and rpm tack jumping
One little correction on ZL1"s advice, the o2 sensor doesn't have enough effect on the pcm to "flood" the engine, at worst it could force the pcm to reduce the fuel trim to lean it out, but would not cause the plugs to foul.

Re: Re: 95 blazer missing and rpm tack jumping
Did you check to see if you have the correct fuel pressure at the check valve. Also I would pull the error codes first. It also sounds like it could be your EGR valve giving you the trouble. Check your codes first. No sence in replacing parts if there still OK........

Since your SES light is set, have you pulled the codes? This would help us give you better advice...Advance or autozone can pull the codes for you..
