High Throttle Power Loss

[RidgeRunner]

Black Mountain in N.C., is only 8 deg. And that is a hard pull on any car! Ask Aaron, he lives in the mountains. (or real close) If you want acceleration on a 40 deg slope, you need more than a V6. (Rockets come to mind) I agree with Ben. Check fuel pressure.

Cog wheels and a top fuel engine come to my mind...

Black mountain is where my car has been overheating lately between my apartment and my parents house.

Okay, I haven't moved the car now in about a week, for the sole purpose of seeing how it reacts at idle throttle. I just came in from testing it out, and I noticed that it will not rev over 3000 rpm's, it just drops down to around 2700 and then travells back up again. Yet if the car is mobile, it has no trouble getting up over 3000 rpms. There's almost like a sputtering noise coming from it as well.

There is a park/neutral rev limiter.

Okay, so the next day I have off of work will be Monday, so I'll run out to an auto shop and grab a replacement PCV Valve and an Oxygen Sensor. Anyone else know what else I should get while I have the chance? I want o make sure I cover all possibilities while I have the free time. As always, any suggestions will be greatly appreciated.

Have you checked the TPS and the fuel pressure?

Hmmm... I'm pretty sure I checked the TPS a while back when I did my plug and wire change, but I don't believe I've done the fuel pressure. I'll give it a shot before I fork out any cash though, thanks.
