9980ASFAThis TBI car isn't running good and I looked everywhere on the net and can't find this broadcast code anywhere. So I'm wondering if this really isn't the right PROM for the car. the car is actually a 91 camaro with a TBI motor.

 

Do you know ECM part number, 1228746??? It would be easier to work from ECM part number.

sorry the ecm label is unreadable. I've seen websites with a bunch of broadcast numbers however this one I can't seem to find anywhere. Maybe it a ecm out of another car type.

 

That PROM is for a 16136965 ECM from a '91 Caprice LO3, TBI. At key-on, engine-off does the SES do the blink? If so then I'd quess that a different ECM was swapped in.

Yes the check engine light blinks when the key is turned on. I will try a ANTS in the ecm and see what it does that seems to be a common prom for a later TBI camaro.

 

I didn't explain the SES blink very well. Does the SES do a single blink off then come on solid? That is OK and what it should do.

If it is continuously blinking then it is the wrong PROM in the ECM.

RBob.

 

Yes it just keeps blinking which is why I assumed the problem was ecm related. I got the correct ECM now just need to hit a bone yard and find a prom for it.

 

Maybe, finding a replacement ECM with a matching EPROM, from a similar car, will be simpler. A used ECM can be had for about $40 from JY.
