Will do when I get back home after work. Light wasn't on last time I started it but might as well do it. Thanks for all the help. I think it fixed it finally after almost 2 years. We will see.

So came home and got started. I had to run a bypass from my CS130 alt to the starter first but that didn't take long.
Next I set min. air based on instructions from another site (basically jumper AB...

Yep, that is what is happening.


After trying all the test, car idled real low. So I did adjust throttle stop. The last shop I had diagnos it removed the cap and adjusted it.( A side note, the...

I'll do the test again but I did find several companies that rebuild and test ECMs.

I'll do the test one more time. If that doesn't work then I'll go buy a ECM locally for $50.

Yeah, I've done all those test multiple times. Ohms are good across AB and CD. Voltage is also good. My next step is usually reseting the IAC. Jumper AB to reset.
No codes present during reset. IAC...

Since I have tested everything I can and my TBI is still running rich and my idle doesn't increase at startup, I'm left with thinking something is shorted in the ECM. Any recommendations to a repair...

Mine only moves when I throttle it. It doesn't move after start up. That is sort of the problem. The car is running to rich and won't idle up at startup. I'm running out of things to test.

Thanks Eagle. Some differences in my wiring diagram and the one you posted. The wiring diag. for my motor says that A&D are one coil and B&C are the other coil. So, Lt BLu-Blk goes to D and Lt...

Six, are you talking about reversing wires across the coils?
That makes sense and it seems that all wiring diagrams for my year and the years around mine are all different. Some have the wires...

Wow....haven't had time to touch my car in forever.....the ECM is a 1227747. I don't remember the BCC. I need to finish my car and get it running correctly. Any help I can get will be appreciated....

Tried the above wiring suggestion but it didn't work. Well, I should say it worked backwards. The pintle opened in diagnostic mode (A & B jumpered). I'm going to reverse the colors and see if that...

Thanks, I'll give it a shot tonight.

Here is the wiring diagram:

The IAC connector is square 4 pin. I remember pulling the block stamping numbers at it is a 350 TBI for a...

My 57 Chevy with a 89' 350 TBI is having an idle issue. I believe I tracted it down to the IAC but need to confirm as it is a new IAC valve. The car doesn't increase idle at startup or the normal...

Lets see if I can get this to workhttp://www.trifive.com/forums/picture.php?albumid=2053&pictureid=17438
I'm still working on it and since I did it all myself I'm having to go back and tweak stuff....

New guy trying to figure out a TBI idle issue. My ride is a 1957 Chevy 210 Sedan with a new 1989 350 TBI and a bunch of other goodies.
