Mustang sat for several months under canopy. Cranked for spring driving and car ran very rough. After driving it seemed to get better but never as good as before storage. I have replaced plugs and fuel filter(was clean and not stopped up). Coil pack looks good, no carbon tracks or obvious damage. Injector cleaner and fuel treatment added. All to no avail. No CEL
Car cuts out badly at start and partial throttle for first 5 or 10 miles then gets much better. Any thoughts would be appreciated.

Ok.....new coil pack, wires, plugs, crank position sensor, cam position sensor, cleaned MAF. One or more of these corrected my problem...runs good now...pulled trigger on dynomax cat back duals and that should be fun.

Have you siphoned out the old gas that's been sitting and added fresh gas?

Thanks for reply...She is running fine now but if it starts acting up again I will certainly do as you suggest. When I parked it the tank was full up with a touch of gas treatment in it to prevent those sort of problems but it may not have been enough.
thanks again

Does anyone have any ideas on WHY I keep breaking crank position sensors on my 1991 2.3 Mustang? Its pretty straight forward and I got a new harmonic balancer to go along with it, and the tabs on the sensor keep breaking and I have no idea why. Its from the balancer. Ive literally went through 7 sensors now and im at a loss on what im doing wrong. It only goes on one way with the bolt holes and bracket, as well as the balancer. Please help!
