Help Please!!!

Hey guys whats up? let me start out by saying im not new but i cant pinpoint my problem. it is a v6 3.1 mfi in a 92 camaro. ive check my plugs, wires, cap, rotor, oil pressure, and intake. my problem is that when i turn the car on it will run, but it will bog down and wont respond to the throttle. when i drive sometimes it will respond and others it almost seems like it wants to die if i give it gas and when i let off gas or drop it in neutral it runs normal. any ideas of what this problem could be? any input would be great. thanks guys

Re: Help Please!!!

Make sure your MAF/MAP sensor is plugged in...whichever one you have, I'm not familiar with the v6.

You'll need an Ohm meter to check your TPS

Re: Help Please!!!

Sounds to me like it's time to check your fuel pressure, with the gauge taped to the windshield, so you can see what it's doing WHILE IT'S SCREWING UP. That is, just looking at the pressure while it's sitting there idling, may not be enough.

OK, we got that part.

So what's the fuel pressure WHILE IT'S SCREWING UP?
