Possible Causes of Engine Hesitation or Stumble:
Dirty fuel injectors (cleaning the injectors often fixes this)
Dirty air filter (change filter)
Dirty / clogged fuel filter (change filter)
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)
Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:
Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

11/17/2012 CVOFirst, check the battery and starter cables for their tightness or free of corrosion and physical damaged.
A 3/4 charge battery is 12.50 volts
A discharge battery is 11.75 volts.
A battery under a cranking load and it is reading less than 7 volts,it will be a recycled ( junk ) battery.

11/15/2012 CVOTrouble Code: P0301
Cylinder 1 Misfire Detected
Possible Causes:
Air leak in the intake manifold, or in the EGR or PCV system
Base engine mechanical fault that affects only Cylinder 1
Fuel delivery component fault that affects only Cylinder 1 (i.e., a contaminated, dirty or sticking fuel injector)
Ignition system problem (coil, plug) that affects only Cylinder 1.
Note: ran out of gas, the fuel pump will pump the dirt accumulated in the fuel tank and it will clog the fuel injector. Replace the fuel filter and add a 16 oz of Chevron Fuel Cleaner to a full tank of gas to clean the fuel injector tip.

I changed my starter and now it won't startchristianmontes1990 - 1982 Buick Regal - Engine - 11/12/2012The old starter was going out and I replaced it and it won't start-
11/12/2012 CVOWon't crank ?
First, check the battery and starter cables for their tightness or free of corrosion and physical damaged.
See this Starting system simplified diagram. Have a help from an assistant to crank the engine, use a 12 volt light tester or a digital voltmeter, apply it to the starter control circuit.
If there is light or 12 volts and the starter isn't cranking, then the starter is the culprit. Have the starter to bench test for free at the local auto parts stores.
If there isn't no light or no volts, then the ignition switch is the culprit.
Check the starter relay and position the transmission shifter to neutral.
