my 1988 mustang gt convertible usually runs great but sometimes it idles up and down and will even die. the problem stops when i accelerate but will continue at cruising speed. sometimes it does not happen for days, then when it happens it can last for a few seconds up to a day. i have replaced the cap, rotor, plugs, wires, fuel filter and egr valve. it feels like a vacuum issue, but i do not think a vacuum issue would come and go like this. i am lost! please help 3 Answers

My son has an 04 mustang 3.8 v6. Having a engine problems and can't seem to figure out what is going on. It starting running really bad a day or so after filling gas tank. We suspected bad gas and treated as such. A couple of weeks have gone by and it is getting worse. It starts up OK and runs OK for 10-15 mins. Then it starts skipping and cutting back. It will shut off a few minutes later. It may restart one time, but will not stay running. If we wait a few hours it will restart and run OK for 10-15 mins.
