ok so I finally found where to plug this scanner in to scan my ecu and following codes showed up 5 in all.
P1131:lack of Ho251 switches lean bank 1 sensor1
P1132:lack of Ho251 switches Rich bank 1 sensor 1
P0305:cylinder 4 misfire detected
P0305:cylinder 5 misfire detected
P0411 secondary air injection system incorrect flow detected

ok what does all this hog wash mean? I reset eveything and got the engine light to go off.

The passenger-side front O2 sensor is most likely due for replacement. When was it last replaced?

P0305:cylinder 4 misfire detected
P0305:cylinder 5 misfire detected

Inspect the ignition system. Check the condition of the wires, the coils and the plugs. It basically makes sense to simply replace the plugs with fresh factory parts. You can inspect the ignition wires for cracks, contamination or damage (e.g. oil softening, heat damage etc).

P0411 secondary air injection system incorrect flow detected

Is the SAI system still intact on the car? Air pump...checkvalves, vacuum lines etc?

It's worthwhile before doing any work to see what, if any codes, return. This will help weed out the "real" from the "false."

ok I just recently bought this car off ebay. the owner kept all his records on repairs and said. he did plugs and wires back in late oct. as far as any sensors he didnt mention any. royal blue fluids changed in late jan this year. it does have 1 chamber flows master mufflers on it I noticed. he stated the reason the check engine light was on in first place was he had a sct tunner on it when he bought it with that was run on car and it was like that when he bought. dont know if it was set back to factory spec's before he got it or not he stated he removed it and didnt mess with it cause he wanted it stock.

he also stated the plugs and wire are motorcraft. I know for shure the plugs are.

Okay. Well, wait and see what, if any codes come back. If he had plug or wire issues back then, fixed the problem (do the wires look new?) but didn't erase the codes, they'd still show up now. By erasing the codes you're starting from a clean diagnostic plate, so to speak. It may take 50-100 miles of driving for the system to do all of its internal tests and to judge whether things like the O2 sensors are operating properly or not.

Is the car showing any driveability problems right now? Misfires? Lousy mileage?

the wire's look new and. car seems to run strong. gas mileage seems ok.
