Hello to all my new friends here on stangnet! This is my first post and log on with this forum so please bare with me! I have a beautiful 1994 Mustang GT 5.0 that has been made to look like the Steedas. Anyways! There has been a lot of mods to this car so far I will list the upgrades at the end of the post. My issue with this freaking car is it will intermittently run horribly including missing, running rough, bad gas mileage, backfires! It seems better in the cold weather and does not do it as much. But in the heat it happens almost all the time! I can go out to her start her up and she runs horrible and sometimes not. As well i can be cruising down the highway for miles when all of the sudden BAM she starts the same issue again. I am at my wits end as to what may be causing my issue and how to test for it and verify. I have tested the MAF, TPS, IAC all the way back to the computer itself everything is showing correct voltage range and grounds. The PCM does seem to get pretty hot though after it runs for a while. Here are most of the upgrades that has been done to my car so far.
