Every now and then my car puts out code 44. the check engine light stays on for a few minutes and then goes off. the car runs perfect. So I am thinking it may be the ECM. 89 Iroc 5speed. Does anyone have a brand new one for sale??

 

I keep a spare. They are still available from part stores (reman's) and on fleabay.

 

I have the one I pulled to put in my EBL P4 ECM.
it is from a '88 5.7 Auto car with the stock chip.
PM me if your interested in it.

BTW Same ECM and connections, the calibrations are on the PROM. Would work just fine as long as the PROMs are swapped.

 

Thank you. I Purchased a reman cardone 77-6571
