The map sensor is the one by the coil pack isnt it.? Hevent checked that yet. Was wondering about the fuel pressure. Have no way of checking it. Have a friend who might have the gauge. I released the fuel pressure at the relief valve, and there was still some pressure but I had a rag around it when I released it so it wouldnt get me in the face. Sounds like an exhaust leak down under the egr valve, But didnt see any thing that looked like soot anywhere around that area. May be a cracked manifold, has a cover so couldnt see that.Kind of hard to get at .Will keep posted on what I find Thanks for all the help SAC

Have another question. If it was a sensor shouldnt I be getting a code from the check engine? Or service engine. Just a thought. I'm not getting either. When I gun the engine from under the hood by hand it gets a little puff of smoke from whereever the exhaust leak is . Only does it if I gun it really quick at the point of almost dieing.. Just cant seem to get a handle on it. Am getting ready to sell it for my son so hate to dump too much money in it but wont be able to sell it unless I can fix the dead spot. Oh well thanks SAC

I'm no help on exhaust leaks or cracked manifolds (sorry). My bad sensors always exhibited themselves with the check engine light and a code. I highly recommend throttle bottle cleaning. In fact, on Hondas it's considered regular maintenance, but not on Chevys, but it should be. What's your odometer? Good luck.

Odometer is 178000. Engine was rebuilt at about 125, but didnt change any sensors. This is the first time it has acted up since the rebuild. Was almost 6 years ago now. Was thinking headgasket but its not overheating. And it seems to run out at speed just fine. Will keep plugging thanks SAC

I know its been awhile but we finally found the problem. I was down to my last straw. I wsa taking the car to the mechanic and it died in the street half way there. Let it cool off, got it going by holding the accelerator to the floor and got it back home. Found in the manual tps sensor. Unplugged it and it would run fine. Allright I'm thinking this has to be it. Put a new one on and guess what? NOT!. Last and final straw. Talked to friend mechanic he brought his scanner over and plugged it in couldnt find anything at first, then noticed temp with running was only 53degrees. Trans was 120 degrees. Hmmmmmmm. he said change temp sensor. HHHAAALLALUYAHHHHHH> I'm on the road again. Just thought you would like to know. Thanks for all the help. SAC

I have a problem with my 95 with the fans also. The passenger side doesnt seem to be working even tho I replaced both. The ac fan on the drivers side works. Where is the sending unit and the fan switch?

I have a 94' Lumina Euro with apprx. 287,000 miles on original motor. The only work I have ever done to the engine is a new alternator. It has come down with a cold though I think. It is surging alot during idol and and stop lights but as soon as I am on the gas it runs great. I have changed about everything I can think of. Is there anything that I might be missing that you guys know about. Any help would be greatly appreciated. Bought it brand new in 94 and aint ready to say goodbye to her yet. Thanks in advance.

My son and I replaced his not too long ago and the easiest way I find is to take a crescent wrench on the tensioner pulley and And hold it tight while you take the belt off. Dont lose your grip or you WILL have busted knuckles.LOL. Make sure you see how it comes off as you will be putting it back on the same way. There should be a diagram on the belt guard that shows you how it goes. Good luck. SAC P.S. There is a square slot on the front of the pulley for the wrench
