when im driving threw town reving at 1500 driving and i will threw a cel once i get outta town speed up to 60 turn on the motor then restart the cel will be gone has this happen to anyone else and if so what did you do to fix it the car is a 1990 hatch with a 1989 integra ls swap thank you.

 

If what you're saying is that... when you're driving your CEL will come on, than you shut the car off. When you restart the car the CEL will be off. This is a trait of your car. check the code figure out what causes it to come on.... :

 

why doesnt anyone ever check their codes ..

 

im having a similar problem.

ill be drivin and when im slowin down the cel will come on...some times it will take a while some times right away but only when slowin down. if im ont he highway coastin it will pop up ill turn the key off then on and drive for a while and it wont come back on till im coastin again.

i tried jumpin it to get the code but it didnt flash.......i can start the car and let it run in place rev it up do whatever for a while and it wont come on....only when slowin down.

i have a obd1 jdm d15b runnin off a p28 if that could be part of the problem pullin the code...

 

i have tryed to jump it and nothin comes up just one short blink every 5 seconds or so

 

well that would be a code 1. o2 sensor code

 

thank you for all the help
