"Service Engine Soon"
My 2005 Bonneville's "Service Engine Soon" light came on a couple of weeks ago. The non-dealer garage "hooked to analizer, checked codes, replaced gas cap, cleared codes, reset" for $64.98 ($19.98 for cap; rest for half-hour labor). Light stayed out for 12 days and now is back on. Any ideas? Go back to garage and . . . ?

Go to a place like autozone and have the code read. Then post it here. Did they tell you what the code was? That's a lot of money to put a new gas cap on. It take all of about 5 mins to read a code, if that. And 30 seconds to put a cap on.

No, the mechanic didn't mention code number. I'll try to get down to Autozone for code. He said he also did a "smoke test" (but it wasn't listed on receipt).

This sounds like a GXP problem that has been mentioned in another area of the forum.
Here's one thread on the problem with some solutions https://www.gmforum.com/t280907/ |

I called the garage and they say to bring it in and they will clear and reset the code this afternoon. I too question the need for a new gas cap, but if not the cap, wouldn't the problem be something worse and still recur until the underlying problem is fixed?

After calling the garage, they said to bring the car in this afternoon. The mechanic (different than the one that worked on it the first time) made note of the code (442), cleared the "Service Engine Soon" light and checked the gas cap that had been replaced, without doing anything further. He said to call again if the light comes on again for a more in-depth study.

442 EVAP system small leak detected
Check the vacuum lines, if it's cracked you have a leak. |
My mom's car had this same code. The vacuum line between the Fuel Pressure Regulator and the Throttle Body had been cracked/open. Inspect all the vac lines under your hood.
