SOURCE: 1988 ford mustang gt bogs down when pushing pedal down

Hard to say if it is related to exhaust or ignition timing if you take the car for a long drive and take a look at your exhaust manifold and if it is glowing cherry it could be related to your exhaust or timing a freind of mine had the same thing happen and the cataliytic was plugged and the timing was out. the cat was probly plugged due to the timing being out.I would also check the timing.It could also be an injector problem,fuel filter,or some other area of the fuel system these problems are hard to diagnose without actual hand on so just check those areas and let me know of any other symptoms hope this helps?

SOURCE: 2003 Expedition jerking/cutting out.

Had same problem: cutting out at low rpm, jerking, a huge clunk or shudder at higher speed (like transmission was going out), and rough idle. All these symptoms were intermittent.

CHECK THE FUEL FILTER!! Changed the fuel filter and thing runs fine!!

PS mine 2003 expedition has 105k

Truck shifts out of gear at 50 to 60 miles an hour jumps in and out of overdrive at those speeds

check the tps ( throttle position sensor ). a bad tps causes transmission shift issues, bucking, jerking, idle surging, engine cutoff, hesitation on take off, surge while cruising down highway. am not saying this does the trick, but it is a good starting point. good-day !
