Hello Everyone. I just joined today, although I use this forum a lot to try and figure things out on my truck. Since I am a 23 year old girl, mechanics like to steal my money. I am trying to learn everything I can, so please, try and dumb things down for me.
I LOVE my truck. In the last 8 months though, I've had to put over $8,000 into maintenance. I really don't have a way to get out from under her, so I just have to keep fixing things as I go.
Shes a 2008 F-250 Super Duty- 6.4L Powerstroke. Crew Cab- Long bed. 130,XXX miles. I believe she is completely deleted with a straight pipe. It came with a little tuner where you can change the settings.
I had an oil leak on the back of my motor and on my mechanic said it was the turbo gaskets. So they replaced them. And there was a leak in the Hot side of my inter cooler? Because it had a hole in it. Then a month later, the oil was was leaking down the back again. So I took it to a different mechanic, because they were going to charge me $800 to replace some bolts. So I took it somewhere else, because my truck started to not have any boost anymore, and they fixed the leak for me. They said my exhaust could plug up, but it would fix itself. Truck ran fine for a few days. Then the boost would max out at 40, but my truck would still have no guts, like it used to. So I took it back, and he plugged in his computer. Said everything looked perfectly fine, all of my numbers were normal. He reset my fuel mileage? Lol sorry, I'm trying my best to remember the conversation. And we test drove it, and it ran perfect. Took it home. A week later, same issues again. And it kinda makes a chugging noise when it gets to 20 PSI. So I let off the gas because it feels like the truck is trying way too hard to get going, and it scares me. Almost as if there's way too much pressure with no where to go out. I will attach a video where you can see the turbo charge fast, but my speed is NOT increasing as it should. I am super stressed out. I asked him, and he hasn't been returning my calls or text. Then he finally responded and said " Probably need to clean your turbos or replace. Can't do much more." But I feel like we should be able to do more than that. Places I've looked said to spray some turbo cleaner into the air intake. There's a youtube video of a guy saying he just replaces the back pressure sensor with the little pipe, and it fixed his. I would rather fix something small that could solve my issues, than spending thousands of dollars I don't have. It's my daily driver, so its hard. I can try to answer any questions, or post photos or videos that can show you what you need to know. I don't know A LOT about trucks. I'm learning as I go.
All of the codes I have are here. My mechanic said not to worry about any of them, but I am worrying anyway. I plan to order the brakeswitch to try and see if thats whats wrong with that code, and the speed sensor for the back axle.
P0703- Torque converter/brakeswitch B circuit malfunction
P0500- Speed Sensor
P2263- Turbocharger performance
P0196- Engine oil temp sensor range
