i have a 1990 acura integra gs with a b16a vtec. my engine light comes on after i have been driving for a bit and it kind of dies real quick but not all the way while its driving, it does this when the light comes on and every once in a while when im driving when the engine light is on. i read the code from the computer and it is 6 long and 8 short. i looked and i cant find what a engine code 68 is. i dont think it is a 67 and i just put a new cat in it anyway. if you can, please help me out. my registration is expired and i need to go pass emissions.

 

You can't find code 68 because it doesn't exist for G2s or G3s. I'm thinking you have two separate codes, 6 and 8.
