Took my daughter's car to Quality for engine light a couple of weeks ago. Previously, another auto shop had replaced the gas cap in hopes that that was the issue for the evap system engine code from the diagnostics. That shop said that most of the time, a poor sealing gas cap is the problem for that system code, but to find out for sure a smoke test of the evap system would be required. Well, we hoped that the problem was solved so we passed on the additional cost for the smoke test with that shop. Soon after, the engine light came on again. So that's how I ended up taking the car Quality for the engine light a couple of weeks ago, so they could run the smoke test. Daniel ran the test (the same diagnostic code for evap system) and to my surprise, they called me in the shop area and showed me the smoke spilling out of the gas cap connection, which obviously was not fixed by the previous shop the first time. So we're happy with a new gas cap, but then a short time later the engine light comes on again - how aggravating! So, I took it back to Quality this morning and Joe remembered the car and me from the recent, last visit. Diagnostics showed an issue with the evap system again, but this time using a higher pressure system test on the evap system, they isolated the additional problem canister and completed the repair.
Thinking this through, once they found the poor gas cap seal previously with the smoke test, (which I came in asking for at the suggestion of the other auto shop) replaced the gas cap and the engine light went off after test drive, it would not have been prudent at that time to try a different costly diagnostic (in this case, the higher pressure test.) I learned that the smoke test is a low pressure test, which perhaps would not reveal the problem with the evap system canister issue - at least that's how understand it (might be wrong.)
Fair pricing for part and labor. Excellent service and personal attention to me - kept me in the loop on the issues regarding ordering the part (GMC problem with part number, not Quality's.) Miguel test drove the vehicle to ensure that the engine light was now no longer activated and I was good to go! I've used Quality for years for all of my vehicles and after using many automotive shops in the Spring area since 1990, Quality is the one I trust most. Mike and his team are good, honest people - just what one needs in an auto shop. read more
