Rough Start and dies, then runs fine.

Me again, this time I cranked over my 2.9 and let it warm up. i just tapped the gas and the throttle jammed at 3,000rpm. I tapped the gas to try to un-stick it from 3 grand, but it was still stuck. i shut it off, tried again, same thing. I waited and tried the 3rd time and it did it but then dropped to the point where it just about died and then idled. Now, I have Check Engine and on initial start, it dies (takes two tries to get it to run) and then everything seems okay. what the hell is wrong with my clunker now?!

1st have it scanned or perform the old fuse box jumper blink test your self and see what it puts out.
Check for vacuum leaks, Try cleaning the IAC, check the throttle linkage out for kinks, binds and lubrication. Check out the TPS as well. Some times they get real gritty and stick ( needs to be replaced if its like that. cant be cleaned out).
Check all the connections you can see for corrosion and oil soaking.
