1998 Savanna 5.7 l. with 125,000 miles. About 3 months ago I had to have #5 wire replaced for mice, shortly there after the van started wanting to stall after starting while pulling out or backing out of a parking spot. Also once the vehicle has run for about 5 minutes it would stall coming to a stop sign or light. At times when pulling out in traffic or from a intersection it will act like it wants to stall but then lunges forward once the throttle is pressed. It appears to run fine going down the road but seems to happen only when pressure is not on the throttle. At about 100,000 miles the crank sensor was replaced while on vacation and stranded. Recently the card before the air intake was replace as a first attempt to resolve this.

Don't really want keep throwing parts and $$$ at it hoping to get lucky, any idea'*???
