I took my car to emissions and failed at 5 hydrocarbons when the limit was 1.5 and i put in a stock ecu, injectors, and maf. The car was at 3.14. I have a turbo back exhaust with a cat but not sure if thats the problem. I was also wondering if anyone has ever heard of putting alcohol in the fuel tank and it worked to pass emissions. Any help would be good, Thanks!
