check engine light help!!
check engine light help!! I have had this check engine light for the longest, I cant seem to get rid of it...it would come on for a few days and turn off on its own, its been on for over a month now and I has not come off I plugged in the troubleshooting scanner and it throws PO442 code: it says (EVAP)Evaporative Emission System small leak/no flow condition
probable causes listed:
1. defective or loose fuel cap (checked)
2. EVAP canister or hose cracked-not connected (checked)
3. purge or vent solenoid defective (checked)
4. vacuum leak at engine (checked)
I dont know what else to check, anyone ran into this type of problem before, please let me know....unless this can be tuned out, I dont know what to do.....

Yea I tried the smoke machine also at local performance shop but didn't see any leaks they told me at a shop they could find it but it was going to cost me 85 dollars an hour for testing until they find the problem, I ain't got that kind of cas lying around, I would rather spend money on an upgrade or something
I literally just got my car back from the shop for this exact problem. Mine ended up being the canister, however, the canister wasn't in the same spot that everyone says it is. Mine was on top of my gas tank, so short of dropping the gas tank or cutting the top of your trunk off there's no other way to get to it. Anyway it ended up costing me 600 bucks to get it fixed. Hope this helps.
Have you checked every hose and fitting that involves the EVAP and fuel systems? As you've noticed '442 is a hard one to find. On my '98 Mustang I lucked out and noticed that the gasket that seals the fuel filler tube to the tank was rotted out. Like I said, check every hose, fitting and whatnot involved in the EVAP and fuel systems...
