hello, my 03 windstar has a jerking or stutter at hwy speeds. Sometimes it will stall while doing 60-70 mph, It will not start in neutral, have to do a complete stop in order to reststart motor. This is dangerous stalling on hwy's with no shoulder to stop on. I have changed a blocked fuel filter and though it runs better, hwy stalling still occurs. When jerking happens, if i let off gas quickly, sometimes prevents the stalling. This has me worried for my safety. Any ideas would be much appreciated. p,s, codes 171,174 are on, but think tsb 13-6-1 would fix that. thx.
