Sometimes after I start the the car and drive slow for a bit I have hardly no power and no codes. If I shut it off for for like 10 seconds and turn it back on its fine. Did a bunch of reading, cleaned MAF, disconnected battery. The problem is random but seems if I drive slow after start up then try to go, feels like it's in limp mode.

 

try cleaning the throttle body and doing the throttle body relearn. And maybe reset the ECU and drive it hard afterwards.

 

Thanks I will try that when it warms up a bit, snow storm here.
