Take a look a your throttle body, it's probably dirty and I'd check the crank position sensor too.

ok well I tryed to have the crank sensor changed but the nut holding on the ballencer wont release and their afraid it will strip or break the crank so that problem is a new one the throtle body has been cleaned it didnt help but the origonal problem still exist so I am thinking about changing my fuel pump at $550.00 + install and my ECM computer at $260.00 plus $88.00 for programing Other than thies I dont know what to do except sell it or trade it in Jim
