my truck makes a hissing sound when i'm accelerating and looses power going up incline. I tuned it up and had he muffuler system checked out.I even double checked the timing. It sounds like normal except for when driving. It also burns more fuel than before. The only thing I didn't do was checked the compression.
please give me your opinion, i've had this truck for about six years and never had this much problem with it.
have the same problem?
