What the heck is wrong with my car if the check enginelight comes on. I have taken it to where i bought it and they fixed it once and now it is on again any suggestions for a fix.

 

Find out what code it is showing and fix the problem. The SES light will continue to come on until the proble is fixed. To reset just disconnect the battery for 5 minutes.

 

The same problem may be back, or you may have new ones, get the thing scanned & find out. Do what the light says.

 

I have the same problem, it comes on wheni start the car, and then goes off 10-15 mintues later, although i know why it is on of course, No Cats , but if there is something else wrong with my engine i wont know lol, so i guess i gotta get a set of cats now

 

I don't know whay year car you have, but if it a 95or older (OBDI), it does not care whether you have cats or not. Get the car scanned & see what the complaint is.

 

yeah, go to Autozone and have it scanned. If the light is flashing (96 and newer, OBDIII) then its a misfire, but if its staying on i think its something with emissions..

 

Its a 1994 RS, so yeah i think ill be making a trip to autozone today lol

 

i went to checker and they only have obd2 scanners i guess and it wont pick up a coad. what do i need.
i have a 93 z28 this shop said that my computer is shot becouse it wont give out a coad or something. so i need a obd1 scanner with a obd2 wire is that what i got.

i think the one they used on my car was a unaversal one
