Porting and polishing throttle body

[xtremeon20z]

I got my tb p&p now when I start it up it revs up all the way then wines down and when I get to a stop sign or red light it shoots to 2000 rpms. I was told it will go away after a week and because my computer will learn the new tb. Is there anyway I can reset it now or do I have to wait?

Pull the ECM fuse for 10 minutes or so, and that will clear the adaptive memory.

[xtremeon20z]

Where's the ECM fuse located haha

[Topspin]

Under hood fuse box. For my 05 it's fuse #27 - not sure for your 04 but there's a diagram inside the fuse box cover.

[xtremeon20z]

Oh ok on the 04 it's 2 PCM fuses PCM 1 which is 13 PCM 2 which is 29

[xtremeon20z]

I pulled both fuses and let it sit about 15 minutes same thing it still revs high on crank and it settles back down to 500 rpms , do u think in a week that my computer will learn this and correct itself like on my friends truck?

I would unplug the wire connection to the TB and re-install it carefully and make sure it's pushed on completely and the snaplock is secure. It's kind of touchy and if not on right will act up. Did you get a constant check engine light also?

[xtremeon20z]

Nope no engine lights at all just high surge at start and unsteady rpms when driving

My experience has been that the adaptive memory learns fairly rapidly. If after a couple hours of driving your problem doesn't resolve itself, I don't think it will without help. You'll probably have to schedule some tuning somewhere. Your ECM is limited in the range of self corrections it can make.

Thanks to everyone especially mr Ken. I got in my truck today started it up no fast rev drove like I stole it no surging. Everything back to normal.

Hey XT, you're certainly Welcome - now go out and get that 13 second time slip!
