Hope someone can help with this issue...the yellow engine warning light on my 1993 civic EG 1.5l VEI comes on intermittently. When it does comes on, all I do is pull over, switch the engine off and back on again. Most of the time it stays off but occasionally the light will come back on after a few minutes drive so again I repeat the process of turning off the car again and back on and then it stays off for as long as I drive it. The car drives fine, good fuel consumption, and idles steady at 850 rpm....The problem seems to have arisen after I replaced the distributor with a 2nd hand one about 8 months ago....this distributor had a worn oil seal and it leaked quite a bit off oil in the engine bay. I replaced the seal on the dizzy thinking this would be the end of the intermittent light issue but to no avail...its less frequent, but it still comes on occasionally......from the research I've done, its pointing to a faulty Oxygen sensor...the one on my car is the 5 wire type and is quite pricy and needs a special removal tool....the thing that's puzzling me is that if fumble around the wiring of the oxygen sensor, the engine light stays off for a longer period of days leading me to think it was just a bad electrical connection and I'd fixed it, only for the dreaded engine light to reappear....has anyone come across a similar problem or have any idea how I can confirm it really is a faulty oxygen sensor...any help much appreciated.
