I was going to take my 2013 dodge van into the dealer to have my spark plugs change on a 3.6L engine , but after watching your video I did it myself and save myself a lot of money. Keep making those great video. Great job guys.

i have the cheap scanner. If I clear a code and then take it into get tested for smog will it show the tech that I just cleared a code? If so will that keep me from passing? This is CA

When you clear the codes, all the monitors are reset. It takes two to three days worth of driving to get all the monitors ready. If you have more than one monitor Not Ready, you will fail. In most states at least. Probably CA too since they are so strict on emissions. In most cases you will pass with only one monitor being Not Ready. If you take your car for emission right after you clear the codes. You will surely fail.

I have bought Launch CR4001 code reader before. It is well worth buying because of the high quality. It works on my Ford perfectly. In fact, the design is considerate – the cable attached to the device and the other end of the cable plugged into the OBD port on my vehicle. The instruction described on the user manual is clearly, which are really easy to understand. I can easily check if the engine emissions reach the standard.
I don’t have to always go to automotive services cause this tool can help me solve some small problems. What satisfied me a lot is the metal dome designed keys which are sensitive and easy to operate with great feelings. Maybe you can have a try.
