Engine Performance problem
1995 Chevy Blazer 6 cyl Four Wheel Drive Automatic 197000 miles
While my truck is cold it runs like a dream but as soon as it gets to normal running temp it begins to hesitate like it wants to stall, and if I don't quickly rev the engine it will. I have to pull over and rev the engine a few times and it eventually clears, you smell a burn off and then it acts fine. It happens the same time everyday and on a bad day it can happen up to 5 times. Any ideas on why this happens?
Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. Could be caused by one of the following below: Oxygen sensor.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.
