No fault codes
My mpfi EA has problems like idling at 1500rpm after driving for a while, wont run after starting without using the accelerator, and the car jerks a lot when i let my foot off the accelerator. The worst thing is one day it runs sweet, the next i get all those problems. I have replaced just about every sensor there is and even the ECU with no luck. My problem but, is that my car wont bring up any fault codes from the ecu, not even a pass code. Has anyone had a similar problem that they've fixed?
