throttle pos sensor
 

okay, so I put in a new throttle positioning sensor today (what a pain in the ass that was) thinking that would solve all my problems...but it was really on the contrary now when the car did fire it had a high followed by a bouncing idle ... now it wont fire any ideas on what could be causing this issue?

also forgot to mention that I put in a new harmonic balancer yesterday just in case that could cause any of this

Did you adjust the tps when you installed it? If not that may be your problem, also possibly vacuum leak based off the bouncing throttle. Maybe a stuck IACV.

Start with adjusting the TPS per TSRM.

What was the problem you were trying to solve to begin with??

well the car wasn't holding idle then also when I step on it in any gear higher than first after 3000 rpm it causes my engine to cut out kinda like its being limited... camshaft pos sensor maybe?
