I need some help again. I finally have everything together and plugged in on the engine, tried to start it up and the engine immediately jumps revs to 3000 and then keeps climbing fast at first then slowly after that. I know that I covered all of the vacuum barbs on the IM when I did the emissions delete. I looked at the IAC on the back of the IM and what I think is the adjustment screw is buried in the IAC. I don't know what to do now, any help is appreciated. Thanks!

 

Adjust the tension on your throttle cable and check tps voltage... There isn't anything that would cause an engine to almost hit the limiter unless somehow it was being or thought it was being revved.

 

+1

 

I'll check the voltage next, I tried to start it up a few weeks back with the same results. At that time I didn't have the coolant system completed (I was too excited and only ran it for about ten seconds). I adjusted the cable tension already so I'll hit up the TPS.

 

Check base timing, and fuel pressure.

 

Start it with the tps and throttle cable disconnected.

 

Even if the throttle cable is disconnected you may want to look inside and look to see if there is any noticeable openings. Reason being is even with the cable disconnected, there is a small adjusting screw located at the bottom area of the throttle body that also controls how far open it is. The cable is just for throttle response. But like they said also check the tps and voltage.

 

TPS wont make it rev by itself. ECU can add all the fuel it wants, but its only able to combust it because you're drawing in way too much air from somewhere.

 

I'll try some of these diagnostics on Wednesday, won't have free time till then.

 

I unhooked the throttle cable and the TPS. The engine wouldn't maintain any idle, it sputtered once or twice jumping to 1K then died. There is a video on youtube on adjusting the TPS I'm going to check it's voltage then get back here. Thanks for the suggestions.
