Private shops charge like $50 just to diagnose and tell you what is wrong with your car. If you are good at figuring out what causes check engine lights and how to fix them, I'd buy the scan tool and start charging people.

 

Most ofmy friends are smart enough to know they can just go to Napa if they only need a code checked...

But with the features this scan tool has, I'm sure I'd get something good out of the deal(s) no matter what.I have a lot of friends who deal with project/hobby cars fairly often and something like this could take a lot of the guesswork out of it for em. Never underestimate the value of someone owing you a favor!!! (I hear the 'Love' theme from the Godfather playing softly in my head...)

well autozone i believe is an american only company...being in canada....not gunna happen. we have a lordco auto parts if it makes any sense...i might just pay to get it checked, cause i know in september i could get it done at my schoolut i dont want to wait

 

well i took the neative cable off and hooked it back up. light was off nd has no come backon yet soo i assume it was triggered an now is fine

 

It will come back on eventually if the problem persists, such as a bad oxygen sensor. You will probably have to wait for it to come back on before the code can be read. Most of the consumer-oriented auto parts stores here (Advance, Autozone, O'reileys, Pep Boys, etc.) have a "free check engine light help" sign in the window, which means they will scan your car and guess at which part you should buy from them.

 

yeah it came back on. the engine developed a slight tick, so i made sure i had the oil topped up...it was near add line but still safe. tick is still there. umm mabe a lifter? or valve adjustment? i migh take it to get it checked ot next week
