so about two months ago i was on my way to work in the morning and the ses light went on, i ran the scanner through and p1121 came up, a few weeks later my throttle body gave out so i bought a remanufactured one and put it in myself. the ses light went away but a few days later it was back on. i ran the scanner again and code p0507 came up, something about the idle control, but the idle is fine its at around 750. ive tried the throttle body re learn and the ecu reset. it makes the light go off for about a few hours but then it comes right back. i was probably thinking it was a vacuum leak but it shows no symptoms, the car drives good. and im running out of ideas. and taking it to the mechanic is the last thing i want to do

 

p0507 is for a high idle i believe (my idle is set at 850 rpm so I get this code every once in a while) and 750 rpm seems high. i'd double and triple check that you don't have a vacuum leak somewhere. did you remove the intake manifold when you swapped throttle bodies? also check to make sure the intake is secure and that the MAF is completely inserted.

 

naw just the air intake, ive checked for vacuum leaks and all other stuff,but there seems to be none, and the car doesnt show any symptoms. today i actually installed an aftermarket intake but still no luck, i scanned it after i finished installing it but its the same code. i have somewhat knowledge when it comes to working on cars, cause im going to school for that and taking it to the mechanic seems like a waste of time and money.

 

so i drove it from san diego to long beach, i reset the check engine light and it never turned on. it only turns on when the car is in park for more than a few minutes. could it be an issue with the computer? it turned on this morning when i was warming the engine up
