I have a 2001 3.8 L mustang, it sat for about a year tried to start fuel pump out, ran great previously. Replaced fuel pump motor only, cleaned tank changed fuel filter and it ran great for about 60 miles. All of a sudden running rough misfires, knocks rough idle. Replaced all plugs, coil pack, EGR and 2 injectors (3-4)which showed misfire on diagnostic. First start idles great feels smooth after 15 minutes same conditions occur, sooner when driving. What should I test the fuel pressure again? 2 Answers

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

OK i'm stumped. I have a 2001 ford explorer(please keep comments about fords to yourself ). I've had 4 episodes where i was driving along with no issues and the even though i am excellerating the car stops running and the stalls out. Once i pull it to the side of the road and try to start it it back fires and qcts like it it out of gas but if you wait 30 plus minutes it will start and run for a bit longer then repeats itself a couple more times but then it will runs for days until it does it again. The check engine light is not on but the check gas cap is on. we replaced the gas cap and it is still on. The first time this happened I had it towed and the mechanic tightened the serpentine belt and fixed the manifold gasket. Does anyone have any ideas???? 14 Answers
