The black car I've been working on is developing a weird problem. When I rev it up to 2500RPM it starts bouncing between 2500 to 2200. It's kind of like when you hit the speed limiter in 4th or 5th gear. But it still revs higher. It doesn't have any trouble getting past 2500, but I'm just wondering why it's doing it. Could it be bad gapping on the spark plugs? btw, it's an 89 single cam.

 

sounds electrical. check your grounds and make sure you have good connections everywhere

 

check the MAF as well, i know they start bouncing around 2500....yours could be on its way out idk just a thought

 

Are the single cam and dual cam mafs the same? If they are, then I can swap it out with the one in the white car and see if that's it.

 

Google it, homeslice.
I don't have a 240, so I can't help.
I do hope you solve the problem though.
Damn, I wanna go drive the truck a bit.

 

I dont think so, s13 dohc mafs are cheap though

 

A DOHC maf would do him no good, cars sohc.

I don't think its your maf David, Ill see if I have a spare to check though.

 

Thanks Mike. And yeah, the problem is on the Single cam 240.

 

oh lol my bad i guess i wasnt payin attention...

 

on the back of the intake modifold i think its called the intake throttle anyways take dat out and clean it dats wat was wrong wit my 240
