I wouldn't need a scanner. It would be the first thing I would check and I would replace the plug for the customer and charge only for the plug. That kind of honestly builds a reputation and loyalty in it's customers. Those days appear to be long gone in favor of a quick buck.

I was going to buy an old 400 big block Chevy truck. I met with the owner at a jiffy tune of some sort. The truck was running on six cylinders and the "tech" said the job would be expensive. I ended in buying the truck anyway. The first thing I did was pull the plug wires which two of them fell apart in my hands. Today's "mechanic" won't even do repairs the old fashioned way - good old fashioned "hands on" trouble shooting and tracing.

I bet the computer told the Toyota dealer that my air fuel sensor was faulty and rather than clean my MAF they just replaced both. That's what auto repair has come to.

I will try again. Sometimes circumstances prevent us from shopping around. You figure a dealer would be honest but honestly, they are some of the biggest thieves around.

It's not like I spent an enormous time to "look you up" your phone number and the internet told me in seconds. I know to stay away from your shop. You justify everything. The last thing I want is a shop to argue with me and laugh at me such as you did. Whatever happened to, "the customer is always right" It's you guys that consider yourselves irreplaceable, and they are doing the customer a favor. Believe me, you need us more than we need you and you just lost a potential customer as well as the many people that I know that may be in need of your services.
