while really getting on the accelerator hard, due to an idiot Mustang driver on the interstate, my check engine light came on. I stopped and checked the code , it was P0014. When I restarted the motor, it went away. Should I be concerned?
When I had the motor changed, I gave the mechanic Ravenol 5 w20 Jag spec oil to put in the motor, I later discovered my new motor says 0w20 . Will an oil change help? Should I be concerned with anything else. has anyone else had his code? If so, how did it turn out!

 

Did you get any other warnings ( Restricted Performance, etc ) with the check engine light? Did the car run any different when it came on?

Have you gone WOT with it after this happened?

I would run 0w20 as recommended

 

No issues with 5W-20 VS 0W-20, long as it was one of the Jag or Ford specifications. The cap on the older engines says 5W.

For the CEL, I'd just monitor the situation....and yes, try a couple more WOT runs.



Don't forget to assure that the warning triangle indicator goes out after a code reader hookup...that could run down your battery.
