Got damn this car, just got my altenator replaced a week ago now another service light comes on....Yesterday I'm driving and the check engine light comes on and message says check emmisson, anybody know what this means?
On my 96, the air filter box has a sensor located on it, check to make sure it's pluged in.
When I change my air filter I sometimes forget to plug that back in, it results in the check emmissons message.
car is sucking gas like crazy, I think I'm getting like 12mpg, I am still trying to get the codes but can't locate the buttons people are telling me to look for, I am going to take a pic of my dash and post it!
you can also clear the codes from that need you must. let the codes finish. when prompt PCM? push the high fan. (High fan=yes, low fan=no. it will read the code again and shortly after prompt PCM clear codes? high fan and it will clear.
