Hi, congrats and welcome.

 

Do post in the Tech section, but since you're here already...

Check the TPS sensor - it's located on the throttle body. The sensor can fail, be out of adjustment or have bad wiring. Of course, the best/first option would be to get that code read. You can google "reading codes mustang" and find one that has to do with fox body cars. You will basically jumper a couple wires in the harness near the brake booster, then when you turn the key on (don't start), your check engine light will blink in a pattern giving you the code for what is wrong. Back to google and look it up.

 

ended up being 1 of the o2 wires were spliced.....patched it up and no more check engine light...I can floor my pony now.....gotta say has some cojones!!!lol thanks anyways guys for the welcoming
