When I rev my motor up to 2000 RPMs (or higher) and just hold it there, after a few seconds the RPMs just drop off. I can't figure out what it is and I've had the car in the shop for 3 weeks now and they don't have a clue either... I really need help on this one.

I thought it might be the timing belt, but it's on right and I've checked and double checked it.

Thought it might be the knock sensor, but it doesn't seem to be...

Does anyone have any ideas? The shop said it's probably going into failsafe mode...

HELP!!!!

 

bad fuel? fuel pump? fuel filter (doubtful)?

 

fuel is brand new. I drained the tank and filled it with 92 oct.

Fuel filter is brand new AEM

Fuel pump worked before I did the swap.... How much does a new one run?

 

crap if i know.

lights dim or anything else crazy when you rev her?

does she take off alright between 0-7k

 

Lights don't dim at all.
I can't even drive it. When I let off of the clutch, there is no power at all. It doesn't even try to rev when the clutch is out.... I don't know what to do.. I'm so pissed and tired right now.

 

Are you sure your sensors are hooked up correctly? MAP sensor and TPS not mismatched, etc?

 

Well, I'm not throwing any codes and the shop that's working on it tested both of those and they came out fine...

 

Does the car turn over fine, but just die a few mins later? Or only when you give it gas?

 

You won't necessarilly throw a code if the TPS and MAP sensor are switched. People have done this and come to me asking why their idle is weird, and I've gone thru the entire rundown: vac leak, air in coolant, bad IACV, etc. Then they come back to me and say,"hey, turns out my MAP snsor and TPS were switched", which is why I wouldn't rule it out.

 

cool, I'll try swapping those and see what happens. Any other ideas?
