mecody21 Posted January 25, 2023 Report Share Posted January 25, 2023 Hi, so my wife's 2017 2.0 ecoboost had the problem with the purge valve and I took care of that. But after awhile it started dying at idle occasionally, and occasionally while it misses while accelerating. I've cleared the codes trying to see when it throws the codes and have noticed it misses and throws the codes when I turn the a/c on. P0012, p0014, p0420 Quote Link to comment Share on other sites More sharing options...
Perblue Posted January 26, 2023 Report Share Posted January 26, 2023 Maybe from the increased load from the AC, otherwise they should only be a coincidence. Check your oil level, low can affect vvt also if you are losing oil into the exhaust it can throw a p0420 code, and coolant level, possible infamous head gasket issue. If it's good, then likely vvt solenoid or timing issue. Slim chance it's spark plugs also. Quote Link to comment Share on other sites More sharing options...

The first two codes are related to the Variable Valve Timing and typical of engines that haven't been maintained - infrequent oil changes. The third code indicates a poor CAT performance, which would be premature for a 2017 so could be oil burning that lead to that. Quote Link to comment Share on other sites More sharing options...
