Recently purchased a 1997 ford escort zx2 and the car keeps stalling recently got it inspected everything passed with flying colors through the computer Car runs well; however when slowing down or coming to a stop locally (not on highway) car begins to stall and then shuts off. I changed spark plugs, filter new what else can I look for. Hope I did not wind up with a lemon. Please help driving me crazy as I use it for work everyday.
