(RESOLVED) Part or full throttle causes rpm to bounce @1500 RPM

[manikbastrd]

So I was driving down the street to the gas station and I did a quick brake boost, and all of the sudden I lost power. I can start and Idle the car just fine and I can get one initial rev out of the motor when I start it, but other than that I just get the engine revving up to about 1500-200 then dropping then back up then down again. I checked my codes in link and I get 0014 which is Throttle position circuit malfunction...Link says that I am still getting .51-5.0 volts from the Throttle Position Sensor, and that reads as 0%-100%.

I don't know where to start or what to do. I disconnected my TPS and got the same symptoms, but the trouble code only comes up sometimes. So, I am really not sure if this is related or not. I also know that I have a slightly leaky throttlebody, and have a new one on the way already.

Any advice is greatly appreciated!
Thanks in advance

So, I adjusted my TPS to .63V at closed position, and switched to my FIC 750CC injectors, and heard my ISC(I think) clicking at some point in there...Now it runs fine...Any ideas?

You say you have link? Post a log. It will be way easier to see what's going on.

Wait? Brake boost with a 5 speed trans and awd vehicle?

Still no idea what caused this problem but no issues since

I had the same thing happen to me once going to work. Whether or not it actually was what caused it or not, but my catch can was full and after i drained it out, it ran fine again. Maybe it vapor locked /ubbthreads/images/graemlins/dunno.gif Ill never know 100% for sure what it was, but it got me back on the road

I have the same issue that just started with me. I turn her on boom start perfect, right after like maybe 3 seconds. There it goes, it goes down to 500rpm from 1500 an stays at 500. Like some hotrod at idle. I tried to adjust Biss screw. But didn't work an it just tries to stay on.... I'm still new at trouble shooting. /ubbthreads/images/graemlins/dunno.gif
