http://autorepair.about.com/library/firing_orders/bl-fo-9941.htm -- check this out if unsure your plug wires were put back on in correct order. Also have you checked the cat converter?


2 things. 1.) Check the fuel pressure (may have a weak pump or clogged filter). 2.) If the fuel pressure is good then check the ICM and/or pick-up in the distributor.
