New Accel Injectors, same problem different hole.

[tccrab]

ECM was bad.
Plugged in a replacement ECM kindly loaned to me from a fellow Forum member and she idles like a kitten and roars like the beast that she is.

I'm guessing that the bad fuel injectors in some way dragged down the injector drivers and caused some electronic component to fail.

Whatever.

Problem has been solved.
Now to find a new ECM.
Anybody got leads on new ECM's?
Not sure I want to go with a rebuilt unit, but will have to see if any are available.

I wouldn't be concerned about a rebuilt unit. My 1990 ZR-1 ECM was replaced under warranty with a rebuilt unit in late 1994 and it is still working.

I would ask a local dealer where they send instrument clusters and radios for warranty repair and see if that place can rebuild your ECM. Here in southern California I would talk to AER (Auto Electric Radio), 1841 West Commonwealth, Fullerton, CA, 92633, 714-871-7357, 800-321-6970.

Tom:

Appreciate the input.
New ones are no longer available, however GM does offer a rebuilt unit w/exchange.
GM part #: 16196394, $149 list price from local dealer.
www.GMPartsDirect.com has 'em for $77, no response when I emailed and asked for an estimated delivery date as it's not a stocked item.
www.ZipCorvette.com, $95.95, but you've got to send yours in for rebuild, wonder how long that would take?
There's an eBay auction for a NOS '90 ECM, but I think $389 is just a little steep...

My local dealer gave me a 10% discount and should have it tomorrow. It was worth the few extra dollars for the peace of mind.

86.00 without the pound of flesh shipping charges. They're pretty good to deal with as well.
