ok i read http://www.240sx.org/faq/artic...h.htm that and i understand everything but how to get the engen check light to blink the error coad.. do i need to take the ECU out and turn the nob? or should the check engen light blink the error coad when i start my car? here is the probilm : i was washing my engen compartment last night.. with some degreaser (no water sprayed on anything) i must of hit something because now my engen check light is on but when i start the car it just stays solid.. never blinks.. (sorry im new to the ECU diag) also a ALWAYS used midgrade gas or premium but due to a sudden lack of funds i was forced to fill up on regular.. i dont think that would make the engen check light come on but eh i dunno.. what do u all think? but mostly how do i get the error coad out of the ECU?
