Ok fixed one problem and found 3 more, anyway whenever the car is warmed up and at an idle if I mash the gas (full throttle) it dies, or atleast drops 500-600 rpms and most of the time dies.

Now when its cold and I mash the peddle it may drop 100 rpms and then revs up, or acts perfectly normal.

If its cold or warmed up and I give it half throttle or anything other than full throttle it revs up just fine.

Any ideas on what could be causing this or how to fix this problem keep in mind I live about 5500ft elevation, not sure if that really matters or not because it never did this up here before.

The only thing I changed on the car that may have done something would be that i adjusted the tps so it read 40vlts on the pfc, (it made it idle correctly)

To me it seams like its getting to much air or to much gas or something like that

ok after doing some searching from what I can find my TPS should read about .45v to .5v however this TPS was reading .30 to begin with, and I couldn't adjust it any further at all, so I had to take and drill out the adjustment piece on the TPS. when I did that I got it to read at .40v wich fixed one problem but now made this one.

So now I'm wondering if this is a faulty TPS, does anyone else have an rb25 with a pfc that could read theirs and see what the tps signal is reading at thx a lot.
