I have a 99 F350 Super Crew with the V10, and about a week ago, I went down to the local convence store for some monchies and left my pickup running. When I came back out, a friend of mine had just pulled in so I stopped to chat with him for a second before getting in my truck. While we were talking, I started to smell gas fumes pretty bad, and figure well I am at a gas station so I suppose there might be fumes. So I didnt think anymore about it, got in my pickup and drove home. Well the next day, I jumped in the pickup to go check out a friends camper trailor and I noticed hat while I was at a light, it was idling pretty rough, so when I got home I popped the hood and started looking around and could smell gas. Well anyways. It is leaking fuel out of the exhaust manifold. so I thought I had a bad plug, so I changed it and nothing changed. Called ford and they told me to try and change out all my sparkplugs for MOTORCRAFT pugs because they seem to have trouble with just about every other brand out there. So I went and bought a full set and paid my local repair shop $230 to replace them. And it Still made no diffrence!!
I am thinking it is a sensor somwhere that has just quit, because I had used the pickup earlier that first day to run around and never any issues. Heck, I have NEVER had any problems with this truck since I bought it in 07. It has lkess than 130k on it. It finally gave me a check engine light the other day, and the guy said it reported Multible engine misfires. DUH! The thing runs so bad now that going down the hyway at 55-65 mph, it feels like your driving on a dirt road it runs that rough and it spits out that good old cloud of whitish smoke (not water, checked).

So, what would make it start missing on so many cyclinders all of a sudden like that? I am going to go out this weekend and test the coils one by one with the spark tester (or is there an eaiser way?) Maybe I had a few bad coils and just never noticed till anotherone went bad. I dont know but I live on Disability and have been out of work for over 3 years and barly have enough maney to live every month. I cant afford a million dollar bill from Ford. I am Mechanicly inclined. Sold autoparts for over 10 years, was a chrysler Mechanic in the early 90's. But now with my back and the lack of tools, I am very limited. So if ANYONE has any ideas, PLEASE Throw them my way! I rented a fuel preassure tester kit but you have to have some return line shut off valve to install in the fuel return line in order to test the fuel preasure...
Well anyways.. ANY Ideas or help would be GREATLY Appriciated!
Oh and where is the dang fuel preasure regulator hide on that thing? wanted to check the vacuum line?
Thanx Again!
