Hey all,
I've searched and I haven't been able to come up with an answer to what may be causing the CEL on my 1994. The CEL comes on once in awhile. I haven't noticed any change in driveability or gas mileage. The light will go off after turning off the car and will stay off until another "trip condition" occurs maybe 10 or 100 miles later. The code is stored in memory though and will blink a 25 when I jumper the diagnostic port. I have recently replaced the 02 sensor and no change. I was hoping that someone had some insight as to what may be causing the CEL. Thanks in advance for any help. |

it could be that one of your injectors is sticking closed or for some reason there is to much air going through your system could be a cracked exhaust manifold sucking in air then when the car warms up it closes the manifold expands causing the crack to close up which could cause the o2 to read lean for a little bit
