I know most of you will know what I am about to write but, this may be helpful for some newbies and not so mechanically inclined people like me:
Check engine light came on my JK Rubicon on Sunday as I was leaving for McLean for the recovery. I stopped, checked my manual which said it would likely only be a major issue if the light was blinking (it was not). Got out and with my limited knowledge popped the hood checked the oil (clean and full), checked the air filter (dusty but generally clean). I shook out a lot of the dust and replaced. Checked the radiator fluid ( little watery but probably not a reason for the check engine light). Checked all the spark plug connections (snug). Finally remembered that a loose gas cap could potentially cause such a light. My gas cap is a locking one so I just went over and spun it and made sure it was on tight. Got back in the Jeep, turned it back on, and the light came back on. Decided to garage it and drive my truck rather than take the chance of doing some harm to my baby.
Took it into to the Jeep dealership (Okotoks) this morning hoping they would just hook it up to a portable code reader and we could go from there. Have done this before at other dealerships and they are happy to do it for free. After all it is good PR and they usually get the work order for it after that. This dealearship wanted to charge me $144 to do a 'necessary full diagnostic'. Yes, that's right $144!!! I walked out (disgusted).
Went down the road to where I get the oil changed on all of my vehicles. He pulled out a portable code reader and read the code to be a vacuum seal or something like that. He suggested I check the gas cap for built up pressure. This time I actually removed the gas cap and put it back on. Light is gone!!! Thank you helpful, reasonable business owner!!!
Moral of the story: I need to learn more about my Jeep and simple mechanical things like this (thank you all for your adivce yesterday on the recovery regarding the issue), never ever go to the Jeep dealership in Okotoks again!!! Next time the check engine light comes on actually remove the gas cap and replace (obviously very simple), continue to bring all of my vehicles to the same oil change place in Okotoks (Can't remember the name but, it is the one across the street from Fountain tire). Yes, he charges a little more but, he uses higher quality parts (oil filter) and he just saved me at least $144. Building a relationship with a reputable mechanic/service person (or any good person): priceless!!!
Maybe this will help someone.
Thanks,
Jeff
