Hello friends, the CEL (check engine light) bulb inside my dash is blown (as well as the SRS bulb also blown). I know for sure they are blown (blew them myself long time ago... long story also). My question is:
will having a blown CEL bulb cause any operating problem? (besides not knowing if ECM is throwing any codes)... could I be running in limp mode? could that be the reason the imrc valve is not working? might it be causing the the engine to run less efficiently? All help is appreciated.
PD.: well, I'm already somewhat limp; imrc not moving when reving over 4K

 

a blown bulb will not cause any ill effects to the performance of the car. you just might not know if something was wrong with the car though. If you dont want to replace the bulb and was wondering if something is actually wrong with the car, you can always plug in a code reader and check for codes.

My seatbelt reminder light is out in my dash. And my brake bulb light never worked from the beginning. Just means that i'll have to remember to put my seatbelt on myself and go out to check my lights once in a while.

 

thanks anzboi... that gives me some piece of mind... will replace the bulb as soon as I install the circuit to trick ECM into thinking I have an oxygen sensor (secondary) and a cat converter (already have it)
