I just got done putting a "new" engine in my 2001 ZX3. When I first started it up it revved a little but found idle and stayed there but when I tap the gas it would rev much higher than it should have then eventually go back down. the last time I started it, it up it revved up to around 3k rpm. After like 30 seconds it went back to normal idle but when I gave it a little gas it revved up to 4k and stayed there til I shut it off after like 10 seconds. I've done some searching about the problem and I read something about the power steering pressure switch being a possibility. The reason I suspect that is because when installing the pump I accidentally grabbed the switch and broke the connector off. The 2 prongs were still there so I just hoped I could still plug it in and be fine. But I dont know if it would make it rev that high. I know other problems could be the IAC and MAF. But my question is would that broken connector make the switch send the ECU wacky signals and make the engine rev like that? If not then what would.
