ok.. I have a pro charged 98 vette. It's a full bolt on car with a blower, and a boosts a pump.. I just picked up the car back in November, and it has been driving perfectly. The one issue has been the oil pressure sensor. It has never worked. I have replaced it 2 times already, and on the 2nd time I noticed that one of the wires was pulled out of the connector. Today I replaced it again, and spliced in a new connector. I take the intake manifold off each time I have replaced it. Along with that I did a throttle body bypass. I put everything back together and fired it up like every other time, only this time the gauge actually works!! I noticed however the car was idling very ruff, and after a couple mins of idling the engine bay started to smoke a little and my eyes started to hurt. I had it in my garage with the door open. I noticed my wideband and at idle was reading 10.0, were it usually reads in the 14-15 range at idle. I double checked all connections, vacuum lines, pretty much everything I touched. I tried backing the car out of the garage but when I put it in reverse, the car stalls out.

A couple weeks ago I got 2 front tires put on the car and afterwards the car was idleing ruff, and I got a mass air code. I deleted the code and it has been fine ever since. Could my mass air have completely gone tonight and it just happened at the perfect time? When I pulled the car in earlier tonight it drove perfectly fine..

Was thinking tomorrow I am gonna pull the intake off for the 4th time and replace the gaskets.

Any other suggestions would be great. I know it's a little vague, just hoping my situation might have happened to someone already.

What...Tear the car apart & it don't run right afterwards.....never

I consider removing the intake manifold far from tearing the car apart.

My guess is a vacuum leak where the manifold meets the head. Squished a gasket or something.

Think I resolved it.. Another low volt mass air code popped up today. I took the maf out and cleaned it and the car has been running well so far. We shall see..

Was going to say pull the maf and clean it. Is the air filter you are using pre oiled? May be a huge contributor or could just be a build up over the years.
