t rex xar was running fine, now wont run for ****. stockish tune hey guys, my car has a freshly built stock internal 346 with a t-rex cam and full bolt-ons. I had the pcm mildly tuned from g_force, basically it was to let the car be able to idle and make sure it wouldn't blow up during break-in. anyways, the car was running fine for about 3 weeks, or 500 miles or so. one day I went to start it up, i t started fine, I let it idle up to operating temp, then off I went.. about a mile down the road the car dies. I start it up, and it won't idle for **** unless I pedal it a bit, and the car is dumping fuel (or at least it smells like it..).
I tried replacing all of the plugs, and I just bought two brand new bosch o2 sensors, and the car still runs like ***.
I get the car tuned tomorrow, I'm just trying to figure out what the big deal is, and what I can do to fix it, as I'd much rather drive the car to the shop (15 miles away) than pay to have it towed...
any info or suggestions are greatly appreciated, thanks! oh, and excuse the run-ons and grammar mistakes, I'm posting from my cellphone heh.

Tow it for the tune or risk damage to your engine that will cost far more than the tow ever could (wash down cylinder walls,etc).
It will NOT run correctly on a near stock tune. Period.

We know its not going to run perfect on a stock tune. But it should still drive. I drove my MS4'd GTO around for almost 2 weeks before it got tuned, and there were no ill effects.
