jshelby861 Posted December 3, 2011 Share Posted December 3, 2011 my Transit started misfiring really bad 2 weeks ago,it was so bad that it would choke down when it misfired almost causing a wreck twice! the engine light came on, it started running better, then did started acting up again the next day, I took it to the Dealer on monday November 21st,and , they replaced the coil and spark plug on the first cylinder, after keeping it for almost 3 days, I picked it up on wednesday before Thanksgiving, I did not get out of town 10 miles before it started misfiring again!!, called the Dealer, they said bring it back in the Friday after Thanksgiving, it has been in the shop ever since that day!, they have replaced multiple parts and even have had Ford's "help desk" working on the problem, this is crazy! anyone else had a strange problem like this?

mrtn Posted December 3, 2011 Share Posted December 3, 2011 Stuttering or misfire? Did it puff gasoline smell out of the exhaust? Misfire can be caused by anything from ECU to plugs and between them. Stuttering may also happen because of bad injectors, clogged fuel filter, bad MAF or TPS. Bad hardware inside the engine block is the least likely. I would replace the gasoline first but you can't really pull anything from Connect's tank with a hose. I once drove by a customs' patrol near Russian border and stopped to ask for directions. So they told me to park it and checked for the use of agricultural diesel. They couldn't get a drop out of the tank with their fancy pump device, so they let me go. I think it's a bad ground somewhere. Quote Link to comment Share on other sites More sharing options...

I was thinking it was the fuel also, (gas) and have tried 3 different tanks of fuel.it is has done both smuttering and missfire, strange part is, that it will clear up after a few minutes, and the code keeps coming up as p035 when they pull it, and even at the dealer they got it to missfire twice, they have replaced 1 coil and 1 spark plug, also they cleaned the carbon, as of yesterday they have replaced the ecm computer and some other parts, (they did not say yet) they never got back with me yesterday about how it ran on the test drive the tech took it on, I agree on the bad ground,that or something inside the engine could be bad also, thank God for the power train warranty! they trans has slipped a few times, but until they get the running problem fixed, there is no way to tell they say Quote Link to comment Share on other sites More sharing options...
