    07 Saleen HD - having problems day after I bought it - HELP

    Last Thursday I bought an 07 HD with 43,xxx miles on it. Truck is really pristine and has obviously has been taken care of. The test drive with the truck and the night that I bought it the truck ran excellent and smooth. We were out of town, 4 hours away. The next morning we drove home. My wife drove the HD truck home and I drove the other vehicle. About an hour from home we stopped and put gas in vehicle and unknowingly I put about 15 gallons of 87 octane in the truck. She drove the truck on home. Later that evening Friday I get in the truck to ride around and the truck runs awful, it sputtered around when I hit the pedal and really got on the gas, but as long as I drove normally the truck done fine. I immediately think about putting 87 grade fuel in and go pick up some Lucas Oil Octane booster and drive some more, no change. Yesterday it had 1/4 tank of fuel left so I went and topped off with 93 octane and still no change with how it runs. It does spit white smoke if you get on the pedal hard and last night the check engine light would come on and go off when I would get on the pedal, once normal driving resumes the check engine light goes off. It's like it's starving for fuel, there is no pinging whatsoever like a vehicle does with low grade fuel. Been trying to research all I could and thought it might be water in the fuel so I added Heet water remover and still nothing changes. I'm starting to get a little worried about this truck so wondering if you guys can help.

    Flashing check engine means misfiring is happening, since it only does it with heavy throttle I would look for a vacuum leak. If it was specific to a cylinder you would have a check engine light on solid with a stored code, so it's likely going to throw a p0300 or 'random misfire' eventually.

    Its absurd, I guess my issue is that they are not 100% sure that it will solve my problem. They have ruled out the coil packs as not being the culprit. But being that plugs are a "wear and tear" item they are not covered by my aftermarket warranty and I'm on the hook to fork over the money to pay for them. They are charging 3 hours labor plus whatever the cost of the spark plugs is. Has anyone on here ever put plugs in these trucks themselves? I have put plugs in many cars I've had in the past; but these look pretty cumbersome to get to.

    If you're not comfortable with changing them yourself, for some reassurance I'd do some searching on youtube for videos on it as a little confidence booster.

    I'm sure if you've done it on other vehicles you'll be fine with this one too.

    It's all about the right tools and you may need some extra swivel sockets and different length extensions here and there so just be prepared.
    Take your time and know that you're not a mechanic by trade and it doesn't have to be done in half an hour. Take all day if you want and enjoy a few beers in between! Spend time with your new truck, it'll be worth it!

    You can do it man!

    Another update, dealer changed out all sparkplugs from Autolites to Motorcraft, problem still persists. Changed out coil packs and problem still persists. They are now going to change out the injectors but do not know what size injectors they are on these saleen motors. Can anyone tell me what size injectors a stock SC HD truck uses. I spoke to the mechanic this morning and he is thinking they might be 39lb injectors and I'm thinking that might be a bit high.

    The dealer should know what comes on the stock trucks. 39 lb injectors sounds right for the Saleen package based off of info from other forums.

    ***
    I got a 2007 Ford F150 Harley Davidson with the Saleen Supercharger, 39 lb injectors, Saleen PCM calibration, and Saleen high flow intake and filter and an Air to Water Intercooler!!!! This is a gorgeous truck with 450 hp and 500 lb-ft of torque!!!!! There is an extremely limited quantity of these trucks and I have one!! In Tampa, Florida. If interested, email me at Claing@mail.usf.edu or call me, Charles Laing with Gator Ford at 813-624-5186.

    It just keeps getting better. Warranty company is saying they won't approve the injectors because they think the supercharger was an aftermarket add on. Is there some way I can prove to them saleen option is factory? I do not have the window sticker
