    91 seville cuts off

    My 91 seville cuts off usually shortly after i take off. drives fine after that. It does idle kinda rough now. but after leaving the ball park's parking lot, it cut off like 3 times , mostly when i slowed down. But again once i drive for a while on the street this doesnt happen. I will probable go to oreillys and get car checked for codes, meanwhile any suggestion on what this might be.

    Ok, I checked codes and got no ECM codes but a lot of code history codes. So I clear codes and now get no ECM codes , current code b21 and history codes r 25, 26 and61.

    Did you have history ECM codes? History codes are important with intermittent problems.
