Ford mustang acting like its not getting fuel

who puts a 4 cyl in a mustang??? 4 cyl cant push that kind of weight,i have a briggs and stratton motor that might work better

Start with a timing check, at higher miles the timing chain plastic guides wear and cause multiple misfire and driveability concerns...of course check the obvious, spark plugs, plug wires,c.o.p,fuel pressure..all basics. .ck engine light on?

it sounds like you did not place it on the shaft correctly try putting it on again

Start by checking for vacuum leaks, compression then a scan for fault codes. One of those should turn up a problem

Are you moving a wiring harness under the dash or on the firewall when you move the clutch pedal ?

One ting comes to mind with your description. The throttle position sensor. They are NOT waterproof and if it got wet, it is shot.

Carol Ann,
Your catalytic converter is plugged up [restricted] This is causing the exhaust to get red hot and causing the reduction in power. You need to replace this part [$$$} The catalytic converter failed because you have been driving the car for months with the fuel mixture excessively rich.
You need to find and fix the cause of the rich mixture or your replacement catalytic converter will also fail in a few more months.

fuel filter is plugged, replace it and that should FIXYA.

Mine had the same problem it was the fuel pump.

It almost sounds like an electronic problem (i.e. ECU). I don't think it would be a fuse because you wouldn't have anything at all. Sometimes when the instrument cluster starts to act up, you'll get a lot of problems with the engine running. In this situation, I would get the car checked out from a Ford dealer before things get worse.
