Five problems related to ignition have been reported for the 2002 Chevrolet Silverado. The most recently reported issues are listed below.
Vehicle shut down while driving at any speed, in particular when the air conditioner was on. Dealer has replaced three times the cap and rotor.
Moisture dripping from an air conditioner hose corroded the distributor cap to the point that the engine would run very roughly and with no power. Dealer replaced the cap, spark plug wires and covered the a/c hose at 22800 miles but the same symptoms started again at 43880 miles.
Condensation dripping on my distributor, caused the ignition to fail (distributor cap) was fixed by applying plastic hose to ac line that was dripping on the dist. Cap. (fixed by dealer) but: the hose now routes the water to a spark plug!!!.
Distributor cap was replaced on four occasions. Moisture from the air conditioner hose caused it to misfire.
Vehicle repeatedly stalled while driving,and would not restart for several minutes.
