Hey guys,
I've been putting up with a problem that I think I might finally try to fix. I had my engine rebuilt last summer and the car has been running great. Occasionally, however, I'll hit the gas and the car hesitates or rolls slow for about a second, and then it starts picking up speed. I think it might be the throttle position sensor but I'm not sure. I replaced the unit but I still have the problem. I think I get this more when it's hot and/or when the AC is on high. Has anyone else had this problem? I appreciate your advice.

yeah, i have this problem right now, ive had it for it a while..but its only on occasion, havent figured out a pattern yet..just random. I read on a website where they give you a step by step to fix it, but it looks like a lot of work. I dont know for sure. I think you "reflash", to use a mustang term, your ecu. I dont know if i can do this though because i have a JWT ECU. Any imput from the 240 guru's?

I would appreciate a link to those instructions if you could find them. I'm not sure it would do me any good but I'd like to check it out.

Thanks,
Matt
