I will add all the new things I've done to the car in hopes to improve something. Replaced portions of the vacuum hoses, new throttle body gaskets, new magnaflow OEM replacement catalytic converter w/ new gaskets, and I've cleaned the IACV and EGR with carb cleaner before. Everyone, thanks so far for the attempts. Still hoping for a shot out of the dark that's a cure-all Hail Mary.

I did some digging. Maybe a throttle position sensor?

Highly doubtful.

It's not setting any CELs? The fact that you replaced vacuum hoses and gaskets makes me even more suspicious of a leak. Doesn't hurt to double check your work.

I put on new stainless steel hose clamps that I tightened with a socket wrench. I would not be able to comprehend it if one was loose but I'll try to spary some carb cleaner around them.

I am actually starting to think it could be the TPS. In the past I've was using cruise control and it would just go from let say 40 to 60 and just not stop. BUT would a bad TPS cause surging of the engine like jerking when releasing the gas pedal, accelerating, and going from either decel/accel to maintaining constant speed.

If the TPS was sending out flaky voltage signals, then yeah, that would do the trick. I would unplug it and spray the connector and the TPS to clean it out and reseat the connector. It could also be a wire in the process of breaking too. Better to check minor stuff first than drop a couple hundred on a new throttle body. The aftermarket Blox TPS sucks.

Also, it wouldn't hurt to find a friend with a scanner and see what the actual TPS voltage is doing... 0.49V is 0% throttle, it should steadily increase as you open her all the way up.

I'll check all that out but back to my other question, would a bad TPS be safe to take out on a 1.5 hour one-way/3 hour round-trip drive, if it is in fact the TPS?

The problem seems intermittent, that's why I suggested loosed wiring. At this point, I don't think it's erratic enough to just fail out of the blue.

It could be. I have AAA.I hope that can carry my car back home if it needs it. I'll look it over after I get some rest. I am heading to sleep but how would I set up to test the TPS with volt meter since I actually have one lying around? Just let me know if you know. Thanks for the suggestions. I need me some sleep if I am going to be driving. Also thanks in advance if anyone decides to drop any other suggestions later in the night. I'll stop by in the morning to see what people may have said and give an update. :sleeping:
