OBDI Scantool/ Emissions

So, my Galant deliverator still wont pass Clean Air Campaign emissions, i replaced air cleaner, sprayed the throttle body, new plugs, cleaned the PCV valve. NOx emissions still high, fixed the HC though. So i threw a few CELs that i assume are from a fouled O2 sensor or misfires. Can anyone let me borrow a scantool before i decide to dump a gallon of Ethanol in the gas tank to make it pass?

 

Are you trying to see what the CEL is for? If you just go to Auto-Zone and they will do it for free.

 

they said they wouldn't do OBDI, just OBDII. Maybe it was just the store, do most other ones do it?

 

bump, help keep an innocent subie from having to deliver pizzas by helping me fix this POS polluting Mitsu. I cant shell out 95 bucks for a diagnostic.
