Answer sounds like a fuel leak more than likely the fuel pressure regulator or the fuel injectors. I had a similar problem with my 1991 Silverado with a 350 TBI . After buying a coolant temperature sensor "The one on the intake manifold which acts as a choke" , I had no further problems . May also be a map sensor . I had similar problem on a 1989 Chevrolet Blazer with a 305 TBI. http://www.autozone.com/N,15900113//shopping/partTypeResultSet.htm
Throttle position sensor is located on the side of the throttle body-in line with the throttle shaft. To locate the throttle body, you can have someone repeatedly push the accellerator pedal (with the engine not running) while you look for the moving throttle shaft. Drew
It's a turbine mounted in the exhaust manifold to give more power and smoother running to the engine.
because of the exhaust
AnswerLook under the throttle body. It's tucked in an ridiculously tight spot. You have the exhaust running right next to which is probably why this sensor seems to have such a high failure rate.
Opening a hole us harder running through it means the work was already done
Put a used one on from a running one
no
The throttle position sensor determines the amount of throttle used when the engine is running at various speeds. If the sensor is faulty, it can be replaced by ordering a new part.
Engine is running lean.
white exhaust and rough running usually indicate possible blown head gasket.
Passenger side of engine next to throttle body. It is the senor with the vacuum line running to it.
probably failed throttle bypass solenoid or possibly throttle position sensor
