Why do my spark plugs keep turning black?
Why do my spark plugs keep turning black?
Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
Where is the timing light on a Monte Carlo?
Connect the timing light’s power cables to the battery. Clip the timing light’s sensor wire to the #1 cylinder spark plug wire (driver’s side, front spark plug). An easy place to connect this is up by the distributor. Just make sure you have the correct wire. With all wires clear of the fan blade and belts, start the engine.
What kind of engine does a Monte Carlo have?
The only engine available for the 4th Generation Monte Carlo SS was the L69 HO 305ci V8. There was no option to get a 350 or any other engine from the factory. The 8th digit of the VIN number, which indicates engine type (L69, HO 305ci V8), must be a ‘G’ for 1984 through 1988 SSs, and ‘7’ for 1983 SSs.
What kind of knock sensor does a Monte Carlo use?
The knock sensor is tuned for each block type’s specific harmonic range, so using a 305 knock sensor on a 350 block will not work as designed. Some engines, such as the big block chevy (BBC), and the newer Vortec SBCs require a little more work to retain the emissions equipment.
