After driving my 91 SC for about 20 min the check engine light comes on. Car runs the same and after 10 min and a couple of hard pulls the light goes out.
It might come on again but not always. Any thoughts?
I had the code checked today and I have 172 EGO non switchin Lean exhaust right side - bank 1 and 225 No knock signal during self test.
I'm not too concerned about the 225 but I have problems with finding where the EGO is located on the car. Any pictures will help.
