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?

Id check the idle speed controller.
Its near the throttle body, and basically the thing controls the cars idle, as well as blipping the throttle when down shifting gears in the auto (Kinda like heel toeing a manual).

This thing can get a little grease and oil in it, (especially if you are running K&N Filters).

Mine starts to stick every 5000K's, so I am always ripping it off, and cleaning it out.

I am fairly certain that this is your problem !

Check out this page. I know the pics are from an EF, but the same Idle speed controller is used on the EA, its just mounted upside down (I think from memory)

Hope this helps

Thanks Xyphoid, i will try that.

I'd still like to know why my ecu wont bring up codes though.
