When driving my 96 contour 2.6 automatic the engine hesitates.The engine feels like not all cylnders are firing.When i punch the gas it is fine but when driving between 30-50mph the power goes up and down.All of the spark plugs have been replaced.Could it be a clogged cat,computer,or injector.It idels rough and has stalled at lights.Any idea's before I shoot it!

Two items come to mind.
1. Have you ever replaced the fuel filter? It could be clogged.
2. How about a tranny fluid flush? Those torque converters can really cause problems.

also have u checked/replaced spark plug wires??? or maybe the catalytic converter is plugged

Power goes up and down uncontrollably? Like when the IAC takes a gigantic sheet?

Have you checked the TB to see how dirty it is? I had the same problem with my old car and cleaned it up with some gas and a brush and then it worked fine.

It's a 96...how's the condition of the wiring insulation on the engine harnesses?

AHHHH take it back to Ford! They put the wrong motor in !

Basic tune-up if the "check engine" light isn't beam'n

I think the wire harness was changed with the ford recall.I put the injector gas cleaner still nothing.I had a tune up in march but had the same problem before march.

I made a mistake its a 6 cyl 2.5 automatic

What is the IAC and how easy is it to change
