I have a 95 camaro stock with a 3.4, when i get the car to 45+ mph the engine surges and the rpms jump from 1500-2000 constantly, ive replaced the tp sensor and im still having the issue, anyone have any suggestions on what else to do?

 

moved your thread to the 4th gen v6 section. welcome to the forum, please read the rules and enjoy.

 

does the actual engine surge or just the gauge???

 

I had some surging in a car before, but that was happening at the drive-in theater. Your situation sounds different. heh heh...
Might be a fuel supply problem, check your fuel pressure at different engine speeds if you can. Some possibilities are the fuel pressure regulator, fuel pump, fuel filter, or your EGR system could even be acting up. Are you getting a check engine light?

 

when my 3.4 was surging it was the alt and battery
