1995.5 Honda Passport.. It just started here lately. When i first put it in drive and accelerate it studders a bit then runs fine. I checked the spark plug wires and the continuety-(spelling sry) and they are all good, spark plugs were replaced at the same time. Could it be a sensor... clogged injector... what???? Any Idea's? And if it is a sensor is there anyway to check sensors or just replace them. Also is there a diagnostic system where you can plug a computer in and check it on this year??
