Re: starts with ruff idol then dies NEED HELP
I know redundant things to ask have you checked your spark plugs? Just trying to help here. See if they are fouled? Also another thing did you make sure the spark plug wires were hooked up even just one off would do this also. Not challenging you if you hooked it up right or not just some symptoms i can think of.

Re: starts with ruff idol then dies NEED HELP
I was going to say a leak down test, check ignition timing, TPS voltage, IACV is operating correctly, unplug MAF to see if it runs better, and also seafoam through the plenum vacuum line to find a leak.

Would I also be incorrect to wonder about the ESC and ECT because those two make lots of funky problems when the go bad.

Re: starts with ruff idol then dies NEED HELP
After re-reading the original post, it sounds like a fuel problem. I'd double check a leak down and filter, it has to be one of those. I can't see it being anything else if he is sure everything we mentioned is spot on. I'm guessing the leak down will show something.
