Why does my Silverado go slower past half Trottle?
The truck starts, idles, and revs normally and when accellarating slowly everything works just fine, but once you get past half throttle it falls on its face and acts like it has a clogged fuel filter or bad fuel pump. It actually goes slower than below half throttle. The bogging gets consistently worse the more throttle you give it.
What causes a car to stall out in fourth gear?
Typical failures include fluid leakage, a vibration at highway speed, and a failure of the clutch to lock up. The clutch only locks up above about 45 mph and in fourth, and maybe third gear, and only after the engine is warmed up.
What happens if you have a bad throttle position sensor?
A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time. You may experience slow acceleration, acceleration surge at both high and low speeds, hesitation or delay in acceleration, and other related symptoms.
How does acceleration affect the gear transmission system?
The issues with acceleration can lead to gear transmission problems as the ECM doesn’t get the correct information about the acceleration. This leads to incorrect shift points which can cause both early or delayed shifts.

What causes a fuel tank to clog in an old car?
Both the government and the insurance industry have extensively tested sugar contamination of fuel tanks and all it does is clog the fuel system. Styrofoam also will clog fuel systems. Many older cars have a drain plug at the bottom of the fuel tank.
What causes poor fuel delivery on an old car?
Before looking at the fuel pump, make sure there is gasoline in the tank.Another reason for poor fuel delivery on older vehicles is a pinhole leak in the fuel line. A good place to start would be to check the neoprene hose connector between the tank outlet and the fuel line.
What should I do if my fuel filter is bad?
Change the fuel filter. Change the plugs, plug wires, disributor and rotor button. Do a system analisis to see if one or more of the half dozen or so sensors is bad. Put some injector cleaner in the fuel tank. Check for vacum leaks. Check the valve clearance.
