We have a 1999 Isuzu Rodeo 4 cylinder 2.2 SUV with about 96K miles on
it. The car has always ran fine but recently it began to idle rough. The
check engine light has been coming and and going off for several months
now, Other than the rough idle, it runs fine. We have changed the spark
plugs and spark plug wires within the last few weeks but it still idles
rough. Any ideas would be appreciated.
