I'm posting this for my girlfriends car she just got...
There are several problems I was wondering what they might be
1. when the car sits a while and starts it smokes light colored smoke that smells like unburned fuel.
2. the car has a bad surge that goes at idle and goes away once the engine warms up.
3. when sitting still, WOT gives the car an awful miss and won't rev up, smoke pours from exhause like when it starts.

No hurry, thanks alot guys.
There is also no smell of antifreeze in the exhaust.

Number 1 sounds like it needs new plugs
Number 2 is likely the IAC
Number 3 sounds like it needs new plugs and clean the MAF

where is the IAC on a 95', I looked all over the engine for something that would look like it. I'll clean the MAF maybe tonight, probably new plugs when it warms up outside, and the snow goes away a little bit more, thanks

behind the throttle body about 3 inches down its kind of hard to see it looks like a round cylinder with 2 wires going to it.

The MAF is clean it looks almost new, and there is no cylinder behind or on the side there is one on that picture. there is a small cylinder on the other side with 2 vaccum lines to it. there is also a square thing behind the throttle body.

thanks

In Dr. FrankenCougie's pic, it is the cylinder just to the left of the TB/plenum. It's attached and laying on the paper.

Just a friendly word of caution. The IAC is held on by 2 bolts, when putting them back on, make sure you don't loose one in the intake. I dropped one and thought it went under the intake. Wrong. It went in the intake. A few days later I found it when the engine ate it. Got a PI engine out of it tho lol.

Off the top of my head i cant remember if that would do anything, but you could give it a try. Most likely its clogged up with carbon and crap and not working correctly. Also you said the MAF looked clean almost new. Did you try to clean it off anyways just for giggles?? I would do that to because you cant always see the dirt and crap. If you do that you gotta reset your eec

I reset it once, I'll do it again, I'll clean both sensors probably this weekend (when the car is home) and hope for the best.

thanks everyone.

Ok, this morning the car would not start without giving it a little throttle. I tried unplugging the MAF and then the TPS, there was no change in how it ran. When the car is driving down the road it has a surge or a buck to it, It seemed to be worse at certain throttle amounts. which is why I tried unplugging the TPS, this made no change. I unplugged the MAF, that only made it worse. I pulled one of the plugs, it had a little oil burned deposits but nothing too bad. It acts funny while driving which makes me want to rule out the IAC.

Its tough to get to and that sucks, but it has to be there. I am about 100% positive that there was never one that left the factory without it. LOL

Don't know why that edit didn't work...
You want to replace number 7. Its on the back drivers side beside the intake elbow.
