roush stage 2. More problems.
 

looking for some insight before i bring it to ford and pay 130$ per hour. the car is missing, stalling, and the guages quite working after running for a minute or two. any help would be appreciated. i put a video on youtube so people could see what its doing. computer is chipped and i have aftermarket keys (not original ford keys), mac prochamber H-pipe and mufflers, Roush cold air intake are the only upgrades.

^^^ That's messed up. I'd be freaking out. I'd take a look at that chip you installed. Put the stock ECU program back and see what happens.

I am freaking out. Chip was in when I bought it. Can't go back to stock. But its not a cpu flash. Its an actual chip stuck on the back of the cpu. About half an inch thick and blue in color.

The chip will just pull out. We had issues in the 2000's with super chips and weird issues like this. We often repaired the problems with pulling the chip out, cleaning the connections, and reinstalling. Is your car modded enough to require the chip ie cams or forced induction?

Sorry just re read and see you aren't modded. Pull the chip out and try it.

I'm not sure if it has cams. I bought it like that. Bought it as a wreck. That's why I have aftermarket keys. I had no keys and no info when I bought it unfortunatly. I will try to remove the chip and clean the connections tomorrow.

X's 2, pull the chip, and see what she does. Got to start somewhere simple!
Even if it is cammed, it should still hold some sort of an idle, and will only idle rough like it had real large cams in it.
My GT ran for a week with stage II cams and no chip, or programmer, and it it idle "ok" at best..... slightly rough, nothing like what you're showing though.

If it's not the chip, what about vacuum lines, or the PVC lines? If any of those are not connected, or properly connected, it will idle rough, or barelly idle at all, and even stall out.
