Intrepid V6-201 3.3L Flex Fuel (1994)
clogged air cleaner or poor ignition output.
Cold fouling is normal after short operating periods. The spark plugs do not reach a high enough operating temperature during short operating
periods. Replace carbon fouled plugs with new spark plugs.
Electrode Gap Bridging
ELECTRODE GAP BRIDGING
Electrode Gap Bridging
Loose deposits in the combustion chamber can cause electrode gap bridging. The deposits accumulate on the spark plugs during continuous
stop-and-go driving. When the engine is suddenly subjected to a high torque load, the deposits partially liquefy and bridge the gap between the
electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned and reused.
Heavy Colored Deposits
DESCRIPTION:
Colored coatings heavily deposited on the portion of the plug projecting into the chamber and on the side facing the intake valve.
