Anyone ever have the problem with your check engine light going off and on periodicly about every other month. its been happening to me and im trying to get some cash to get it on an OBD to see whats up.
More then likly your o2 sensor is going....take note at when it happens first thing in the morning cold days etc etc...also check your plugs see if they look ok or its running rich. this will cause the light to flash on and off. one of the few self clearing errors our cars have
yeah i think it was the o2 sensor, my brother had the car before me and right before he stopped driving it he had commented about the check engine light going off and on. then the 240 sat for about 2 years and when i was working on it the check engine light was on. but after driving it down to the gas station the check engine light turned off, so i think it was the o2 sensor picking up nasty gas. it hasent turned back on since i put gas in it
