The first thing to do is post the model and year of the car. Also post the trouble codes - both current and history. There is information on this site regarding reading the trouble codes for various models.

yeah i know how to do the codes but i suck and didnt remember to post them


i finally got all the engine ones off, took an icm, isc motor and for some reason, the 02 sensor was unplugged haha

but my other codes are I039 (loss of road sensing suspension data)

an I052 which is i think keep alive memory loss
