Just an update guys...its fixed!
I took off the spacer, but that didnt fix the issue. I then took off the throttle body, took off my TPS, and replaced it with the original from the original throttlebody. That also didnt work. I then had to drill out the bushing that was included with the new throttle bottle , this bushing was in the tps shaft and the tps sat on top of it. After drilling it out, this allowed the tps to go a little deeper into the shaft. I also had to change my battery as it had died on me.....and boom, I had a good feeling it was fixed the second i put it into gear, the car did not jump/jerk. and thats it. car worked. driven atleast 100 miles already, normal shifting, even after its nice and warmed up to optimum temperatures, runs great on the highway. all is good.
Culprit. : Original tps needed and needed to drill out bushing in tps shaft. Possible battery issues, replaced!
