Need help with my 92 Stealth RT Twin Turbo
Hey guys, I am new to this so please bare with me. I recently bought a 1992 Dodge Stealth RT Twin Turbo and for some reason it won't let me go above 4500 rpm in any gear. I have read around about it might being a bad throttle position sensor. The car also sits at 1000 rpm at idle and goes as low as 500 rpm and sounds rough (almost like its about to stall). I don't know if this has anything to do with it but it does have an hks electronic valve controller and a boost controller, I just turned them off in case it was an internal problem and I didn't want to put the engine under any kind of extra stress. If anyone can help me, please let me know. If you need more info just let me know.
