while i was driving, the g went to limp mode, and i stopped for bit and turn the car back on it drives normal again, but i need to step on the gas a little to make it start, when i get home i was sitting in the car for bit, and the car start revving by it self and it went to limp mode again, scanned code saids p1122, p1126

replaced my throttle body recently and clean MAF sensor did a idle relearn, any clue why this is happening?

That code is specifically for the throttle motor RELAY located in the IPDM. Swap it with the AC relay and see if the problem goes away.

 

I have a theory when on limp mode reset all codes once reset reprogram car once reprogrammed car reprogram key then try driving the car for a few miles to see if it drives better. If it doesn't check to see if check engine light comes on or anti theft alarm is engaged. Car anti theft light on or check engine light on then your car definitely on limp mode still. Unless u find out what's causing the check engine light or anti theft light alarm to stay on them your car won't drive normal try reprogramming key as well. If your anti theft light or limp mode is on that's gunna make u buy all kinds of car parts because it throws codes out there even if it's just a bent wire just dnt believe mechanics when they try to convince u I need a new transmission lol and dnt buy new batteries for it test ur battery first lol

 

He's not having a NATS anti-theft problem, he already pulled DTC's so he knows why the CEL is on.
