It threw a few codes
P1514 Throttlebody performance
C1278 TCS Temporarily Inhibited by PCM
DTC P1515 Control Module Throttle Actuator Position Performance
DTC P1516 Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance
This has been doing this on/off for a while. It was actually fine for a few months. So I didnt bother messing with it.
It stalled on me a few times when driving at low speeds, also it feels like it surges/bogs a little on its own when idling/driving. that usually happens a few mins before it sets the codes and then the REP light comes on
Could this be a TAC module going bad? From what I've read, this reduced engine power crap seems to be a common problem.
Any ideas on what I should do?
I figured this weekend I'll-
Check ground wires- front ones had a lil corrosion. I cleaned those up.
Check connection at TAC module
check to see if throttle blade is sticking- Checked and it's not sticking
Any other ideas? All help is appreciated
