I'm hoping someone has some easy test scenarios for me before I take it to the dealer. I have a 2001 GTX-DI that was running fine but has started to act up but only when accelerating. Starts and runs fine when idling with no error codes or beeping. As soon as I punch it the light comes on and it beeps and shows MAINT on the info center. It also goes into limp home mode. It continues to idle just fine and sounds good. Any thoughts of easy things I can try before I pay the price? I have a Clymer manual so I know there are several things related to several sensors. I just wanted to see if anyone on here could narrow it down for me a little more based on the exact description of my problem. Throttle position sensor seems like a likely culprit.
Thanks in advance for your help.
