Hello again. I have the reduced power and check engine light like before. I have replaced the EGR valve, TPS sensors on engine and gas peddle, and a mechanic ran two new power leads to the TPS on the engine. The mechanic now thinks it might be the throttle body, if so where can I get one for a decent price? Looked on line and they say not for my vehicle. I could use a hand and thanks.

Try cleaning throttle plate on both sides and iac hole with choke cleaner first but it may need a new throttle body and or gas peddle assy It may also be apcm problem so a pro should really look at this.

That usually means there is a problem with the throttle by wire system and its in limp fail safe mode. You need to have the computer scanned for codes and let me know the exact code numbers you have not code descriptions.

The manual if like a year or two to yours should be sufficient the 3.0 and 3.2 will have minor differences.

Here is a link to an article that features written instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. Most scanners are inexpensive to purchase, you can purchase one from Amazon.com. Once you have the codes please get back to us so that we can further assist you. Thank you for visiting 2CarPros.

Thanks guys. I have the codes P1125, P1295, P1299, P1515, P1340, P1326, P1310. I think some are for the transmission for the reduced power and I had to drive it home. From this site and others I am reading it is either the TPS or the one on the gas peddle. I replaced the TPS about 3 years ago but that could still be the problem. Any help is welcome and thank you

Hey Bill,

Please clear the codes and take it for another short drive as soon as the light comes on run the codes. This will bring up one or two codes that will help us find the problem. With a list that long some codes are false and we don't want to start going down the wrong road to fix it.
