Misfire is usually caused by faulty spark plug wires or spark plugs or both. I don't see the throttle body causing misfire.
Hesitation can be caused by several things: 1. A faulty throttle position sensor might cause hesitation. 2. A faulty MAP or MAF sensor might also cause hesitation. 3. A problem with the engine control module might cause hesitation.
A faulty ect (engine coolant temperature) sensor can do that.
A bad TPS might cause the engine to not fire up during cranking. But not crank? Nope.
You don't have a carb on that vehicle, it is throttle body fuel injected.
What would cause the engine not to restart when hot Chevy Trailblazer 2007?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
can a chevy truck with a 350 engine with a tbi cause detonation and pre- ignition?
Plugged fuel, air filter, or catalytic converter can cause that.
The throttle body on an engine houses the throttle, which controls the amount of fuel that enters the engine. It controls the engine's ability to maintain an idle, prevents stalling, and aids in acceleration. If the throttle body is dirty, it can cause problems with the engine running properly. During a standard service, sludge and carbon buildup out of the throttle body and off the throttle blade. The vehicle's computer is then hooked up to a special machine for an idle relearn procedure.
It can cause a rough idle. And it will also cause the engine to die when coming to a stop at times.
throttle body
The motor chokes at full throttle because either the exhaust valves are bad and cause the motor to loose compression at full throttle or the carb has an air leak.
