Throttle Problem

[Cash]

I went to drive my 240 yesterday, but something odd started happening. Unless I have the gas pedal to the floor, it's as if I'm not pushing it at all. So basically I can either go 90-100% throttle, or nothing at all.

When in neutral I can hold the gas pedal down about 10% and the RPMs will slowly rise to about 2500, and then drop back down to 1000, then back up to 2500..

It just started doing this yesterday. Last weekend I drove the car from Flowery Branch, to Atlanta, then to Athens, then back to Atlanta with no problems.

I have a SR20DET tuned on a Power FC. I'm wondering if it's a problem with the Z32 MAF. Anybody have any ideas?

Monitor the voltage of the tps. That's what i would do second, after checking for stored codes. Hold the throttle at the problem area (%) then see if the voltage drops off or fluctuates. Also make sure the voltage is correct for closed throttle. This would at least help eliminate the tps as your problem. GL ;)

For the mafs problem search...., could also try unplugging, checking wiring, and looking for leaks after mafs all that good stuff. See (normally) the maf is at the front, so anything after it can be a problem for it\you.
We can help u eliminate possible problems but.... it's just so many!

Thanks for the suggestions! I'm new to the PowerFC, but I found out last night that I can check the MAF and TPS voltage from the commander, so that's what I'll do next time I get a chance to work on the car.
