Stumbling start...
I have an 03 250 and 1 out of every 4 starts stumbles pretty bad to start. --When it starts these times it just acts like it doesnt want to fire off, once i let go of the key the truck sputters and shakes a little bit and then fires off fine, runs fine, no smoke, no codes.
--I have also noticed that if i let it sit up and get cold (12 hours or more) that it will turn over for about 7-10 seconds before it fires off. When it takes this long to start it never stumbles, it just starts up and runs like a top. (Side note when i say it gets cold i just mean cools off, its been around 100 here for a month or so, but i have the same problem when it was 20 degrees outside).
Does anybody think the EBP sensor could affect this, i have actually gotten 2 EGR low flow codes in the past month and my egr valve is clean. I read that the EBP caused some issues with the 03s and would give a falso no flow code, however all of the symptoms caused by the EBP that i have read about are running problems. I have no running problems, only starting problems.
