Any way, my problem is a misfire issue. I have replaced the coil pack, 3 injectors, cam sensor, crank sensor. My friends scan tool said the MAF sensor was not reading any air flow. I swaped that out also, then I got a code for air temp to high, and MAF code. I am so frustrated with this truck I don't know what to do. I took it to 2 garages, they both said I have good compression. Although the one garage said it may be a valve issue. Some have sugested it may be a bad body ground. As far as I can tell its grounded. The miss fire is always in the 4 or 6 cylinder. New coil pack also and the garage tested it and said it was working fine. Also the garages both said there was no vacume leak.

Whats next? Do I bite the bullet and take it to a dealership?

 

Readers are going to want more info... year, engine size, mileage etc... Garages aren't going to be too forthcoming with info when it comes to telling you what's wrong with your vehicle so YOU can fix it. They need to make money because they like to eat too. RonD is a guru on this site. Best listen to him if he chimes in. If he tells you a chicken can plow a field, you best hook it up and get at it.

 

lol, I hope he has a chicken that can fix my truck. Good point. My truck is a 2002, with about 119k miles and the engine is a 3.0 with a vin code of U. I am new to this site so any info is appreciated. Also this weekend I hooked up a new MAF sensor. When I did I got errors for a bad MAF sensor, and air temp sensor to high.

Thanks guys!
