I went to the mall today and on the way my vehicle drove fine. When I left to go home, the car started but when I hit the gas it hardly moved and my check engine light came on. This continued as I moved the car to an open area of the parking lot. I turned off the engine and restarted it. When I pressed the accelerator, the engine made no sound and the tachometer did not move. I turned the car off then on again, and the car drove home fine, except it hesitated once when I hit the gas, almost like it paused then down shifted. The check engine light is still on.

Take it to Autozone and get them to scan the computer for code/s this is your starting point finding out what's causing the CEL to come on.

Just tried it again. After first starting, it doesn't rev and the A/C doesn't pump any cool air. After a minute, starts to rev like normal again and the A/C works.

. The check engine light is still on.

There's a problem within the engine management system you need to get the computer scanned.

Makes sense. I had that (or some part of that) replaced about a month ago. It was done by an independent mechanic but this time I will take it to the dealer to see if it was done right.

Took the car to Autozone today. The readout was:

Throttle actuator control motor relay circuit. Probable cause-

-Open or short circuit condition
-Poor electrical connection
-Failed TAC motor relay

Shortly after leaving the store, the check engine light went off. Is this because it was read by the code reader or should it stay on until the problem is fixed? I made several stops out in town and the problem from yesterday never repeated itself.

If they erased the code and came back on-there's still a problem within that circuit-could be the TAC motor rely itself, wiring and computer
