I'm not sure the year and model, but I know it's a Cherokee, in the '90's with under 100K on it, but he's telling me that it runs really rough and stalls out when it's cold, but after running it for about 45 minute, it smooths out and runs like a dream?!

Any ideas from you guys? He's about to replace the ECM, I told him to wait, didn't think it could be that, due to it running better when it warms up.

I offered Him $500.00 to take it off his hand, he may be getting frustrated enough to fold..... LOL

Thanks,
