Hello,I have a 94 Q44 with 134,000 miles.My problem is that my check engine light stays on and has been for about a year now. A checked the codes a month ago and it gave me 34 (KS). My registration is coming up and a smog check certificate is required and the shop tells me the car won't pass if the check eng light is on.I checked the codes again yesterday and got 55 (system ok) eventhough the chk eng light is on solid (not blinking).Isn't it supposed to blink for ECU to get a code? because mine staty on without blinking. Could it be something else (simple, egr cleaning, spark plug or something like that) instead of a KS or injector issue?
How can I make sure what the problem is if the ECU gives me 55 system ok however the chk eng light is still on withoug blinking?
Any help would greatly be appreciated.
