    That is what I was thinking, right now it is running fine after ecm removal and re installation. Possibly a bad connection on a pin? Not sure.... I will wait and see. I cleaned all the grounds and checked continuity to ground from the harness and the bolt it goes to. Checked the simple stuff...

    Carbon clean? Intake removal and carbon build up is removed... pretty common issue if the EGR leaks like mine did. And it idled fine before hand. I checked everything for leaks and found none. It idles fine when the ecm is reset. But slowly the IAC opens and bumps up the idle after each key...

    So I did a carbon clean to the old 3fe and now every time I cycle the key the idle goes up slowly 100rpm per cycle and stops at 1200rpm. Removed cleaned and tested IAC according to the fsm. Iac works fine. No intake leaks. If I plug the inlet to the iac it idles perfectly. If I reset the ecm it...

    6mpg from a 3fe!!! What gives!!!!

    Nah mine runs warm on the hiway, gets to half and stays there. Don't think it is a cooling issue. I found my FPR not hooked up. I re connected it but I think it blew the FPD being unhooked for god knows how long.

    Not to sure what you mean. If you mean the cooling fan for the radiator yes it it.

    Hmmm okay. I will have a look at them next. I found my FPR was not connected at all. Along with a s*** load of wiring mistakes. Slowly making my way through it. Egr delete is done I used the same link to do it. Thanks :)

    6mpg from a 3fe!!! What gives!!!!

    The thermostat is new and fan clutch is working great. i was thinking the cats are plugged but i am going to replace the FPD and the FPR first and re check my mileage. i reset the ecm already too! thanks !

    Odd issue with my 91 3fe!! HELP!!!

    I am well aware my truck is 24 haha. My other rig is 34 years old, I just wanted to make sure if there is a way to check the FPR and FPD to verify operation. I am well aware parts wear out and need to be replaced. not my first or last 20+ year old Toyota. I will see availability of the FPR and...
