2 Errors, running rough, no power on 4.7l 2006 Dodge Ram
I just bought this truck. I took a gamble when I bought it. It was sold as-is,runs and drives, no further information. '06 4x4 quad cab long bed for $4800, I took my chances... Anyway, the engine (4.7L V8) sounds smooth, no knocking or tapping, maybe a slight miss, but really it sounds good. I put it in Drive, and can barely move on a flat surface. Speeds top out at about 5mph. The truck has no ***** at all. And I hear a very loud hissing sound when I try to accelerate, but I cannot visually see a vacuum leak anywhere. I get 2 Errors P0068(MAS and TPS sensor) and P0113(Intake Air Temperature Sensor). My scanner won't read the codes, it can't connect for some reason, I read these by the "triple key turn" technique. The truck was sitting for a few months before I bought it. It literally has only been in my driveway for 3 hours so I did not look it over completely yet. I just want to know if these 2 errors would cause the truck to run like this?
Also, In neutral, I can't rev the engine. It bounces between like 1500-2500RPM if I hold the gas all the way down. Is that maybe a safety feature or something? Other than this one, the newest truck I've ever owned was a '97 so I don't know the electronics on these newer ones yet.
