started out with bad fuel pump so replaced fuel pump, fuel filter. got vehicle back 2 days later car started to try and stall again took it back they said it would not do it for them gave it back to us. Ran it for 2 more days and it started again to try to stall when coming to a stop. Took it back immediately. they had it for a week still no solution told us it would not stall for them and they again could not make it stall. nothing showed in there test. by the way no check engine light ever came on so nothing on computer to reference I would imagine. It still trys to stall intermittently so we use it sparingly as they can't find the problem anyway. Any Ideas???
