OBDC. Check engine light came on. Oxygen sensor and another sensor replaced. Check engine light came on again later that same day. Not interested in pouring more money into that sinkhole because I view the OBDC as more of an endless cash generator for mechanics than a useful tool for true diagnostics and repair. Car runs fine - just need to ignore the check engine light. I am thinking about sticking a small piece of black electrical tape over the "warning" light!! |

Fuel smell under the hood and inside when the car is stopped at the red light. Could smell it around the car after shutting engine off. 3 visits to the dealer (Richmond Hill Hyundai) said no problem, washed the engine, problem persists Fuel smell narrowed down to between ports 2 and 3. Pulled the intake - the groove for the intake gasket on port 3 is warped, gasket doesn't seal, thus a minor fuel leak. Replaced gasket, problem still persists. Pulled the intake again, applied Permatex gas-resistant high-temp silicone around the gasket. Fuel smell is almost gone, at acceptable level now - cannot smell it inside or outside. Ideally need to replace the intake - an $800 part. |
