Excursion 7.3 stuttering?!? Any ideas?
I have a 01 Ford Excursion with a 7.3 in it. When we purchased the truck, I was told that it had a performance chip in it, it has over 260,000 miles on it. I love my truck and refuse to get rid of it, but my husband is beginning to get frustrated with it and is on the verge of telling me that it has to go...
It has been idling rough, barely noticeable, but its my truck, and I notice it, and a couple of weeks ago, I was driving to daughters school and it shut down, I pulled it over, stopped it and then restarted it with no problems, it did it again about an hour later, but has not done it since that day. I changed out the CPS yesterday, and am getting ready to change the oil in it as soon as it cools off from driving it this morning...
The ICP is bad and needs to be replaced, there was oil in it when I unplugged it to trouble shoot... THe Check engine light is on, and when it is hooked up, it throws codes glow plugs 2, 4, 6, and 8... I was told that it is more than likely the glow plug relay, rather than 4 glow plugs going bad at once?
It does the stuttering when I am barely in the gas, and only for a few seconds... if I goose it, it stops stuttering and drives like it should... I am stumped... Would a bad ICP cause the stuttering, even tho I have the ICP unplugged right now?
Thanks in advance for you alls help... I aint afraid to crawl up under my truck and get dirty, I just need an idea as to where to go from here...
