My truck has been idling rough, and the fuel injectors are actually starting to get noisy. I just recently replaced the original fuel filter after about what, 20 years? I could barely blow through it. Anyways, the fuel injectors are about $120/ea for a decent OEM equivalant, so I did a search on ebay, and low and behold a new Holley TB for my truck for $199 buy it now + $20 shipping. This same TB is $420+ from Summit Racing. It is a direct bolt on for my truck with new injectors included and I think the throttle body even has an adjustable fuel pressure regulator. They claim 25% HP and torque, but as far as I am concerned as long as I don't lose anything, I will be very happy.
