Hello. I have a 1992 accord 4 cly MT trans,
I have been getting a cel after driving for about 20 mins, but When I tried to pull the codes nothing is saved and the check engine light does not even blink to show i have the jumper in. it just light up solid . ? Odd.
Any one else run into this and figure it out ?

I do have a little bit of jerking while driving , going to do a tune up soon. but if it's a misfire it should save it I would think

 

before turning off the car, safely pull off and retrieve the code... again, without turning off the car

 

Ok. i'll give it a try when i get home . Thank you
