Do you smell a lot of fuel? That sounds like my car when one of my 800cc secondaries stuck open. It drove a little and then died, all the while popping and running rough. If you can't think of anything else you could get all 4 injectors cleaned.

 

I had a similar prolbem when one of my ground wires was not connected properly. Its kinda hard to determine what would cause that kinda prolbem.

 

well it ran like a raped ape till i hit 15miles.. i know that cat had something to do with it bc i could smell i could smell it.. but i dont know why its running so rich
