Hello I've got a chevy silverado 1500 4x4 with a 5.7 litre and while driving at 55-60 mph1500-2000 rpm the truck bucks as though it has water in the fuel but that is not it it has 194,000 miles on it the check engine light has been on since 186,000 miles I think it's the o2 sensors or throttle positioning sensor but not sure I just know it is getting really annoying thanks for your time

Been reading you guys for years. FIRST POST!!
Bought new in 2000, Z71 5.3 w/3.73 rear. Presently has 27,000 miles. When new gas mileage around town was 15-16 mpg. It has steadily decreased as time went by to 13-14 and 11-12. Last check was 11.5 mpg. Same driver & area covered. serviced every 3000 and air filters changed when needed along with injector cleaner. Chevy dealer can find no problems & no codes.
ANYONE have any ideas why????

Well, I admit you guys are right. I bought one of those Poweraid throttle body spacers, despite what many have claimed here, and installed it on my 05 Silverado 5.3 CrewCab. I know...there's one born every minute.
No noticable difference in power or gas mileage. Truck seemed to run rough after the computer adjusted to it. The most annoying whistling sound would cause me to turn up my music way too loud. I took it off and threw it in the closet. I did keep the K&N FIPK, as I have not noticed buildup of "gunk" in the throttle body after 7000 miles--clean as a whistle.
Next for me--headers. What is recommended? Long or short? I have the Z71 package...if that makes a difference with clearance on long tubes. Thanks for the good info.

3500 ram dually diesel power problems,want to know what can cause this. Taken to shop diagnosed as nothing in particular. Could be fuel pump, could be sensor ??? No specific(s) given. Can bad fuel cause this? Station near by had flooded. They had drained the water out after several complaints. Several days went by before I had to fuel up their, once I did the problems started. Surging, loss of power, just an erratic behavior.

Shorties are great at high rpms. Long tube are better at developing low end torque. Your choice. The shorties are plug and play. Long tube requires professional installation unless you're pretty handy with a mig welder.

My in-law is a truck driver and he knows when he gets bad diesel fuel because the truck starts running like crap. I would try to avoid that particular station for a while and see if your problems clear up.

I have the truck you are looking at(2005). I just got 19.3 MPG on my last fill--90% highway. Never have gotten below 17 when driving around town with a heavy foot. I haven't towed anything yet. Only mods are a cat-back flowmaster and K&N Intake. I have 7000 miles and have had no problems. This truck is awesome!

I have an '03 ext. cab 4x4 with 22k miles, 4.8L. I can't seem to top 15.5mpg even all highway. I've been averaging 13-14mpg with a mix. I did much better with my 5.3L Tahoe, but for some reason this truck drinks the fuel.
As for reliability...it hasn't left me stranded. But I've had lots of brake problems which I'm hoping has now been fixed since I went with non-OEM pads/rotors. These ones make a little more noise, but the truck stops better and if the rotors last more than 10k miles I'll be further ahead.
Overall the truck is decent, but I'd be hard pressed to buy a new one right now. The Ford/Dodge trucks are better IMHO (they are much newer designs) and Chevy has a complete redesign coming in about 6-7 months. I'd surely hold out or buy something else. That's where I am right now. I'd like to buy a new truck now, but I'm going to wait and see how the new GM trucks shake out next summer before making a decision. I own two Dodge HD's right now that we use for hauling horse trailers. If I had to buy a new 1/2 ton today, I'd buy the Dodge. I recently drove Ford Supercrew and Dodge Quad back-to-back and both were far better than my truck. The Dodge was a better setup for me (bigger bed but still has normal doors) and the Hemi with 20's and all-wheel-drive was nice.

Is the muffler on the 8.1L the same as the muffler on the duromax?
