I called him because I was looking for a mobile mechanic. I didn’t feel comfortable driving my car anyway they came. For a P3 497 I was hoping he would come with a different scanner. I erased my last review because I went. I kind of went out of hand, but he said he could take care of it. I did research and I can’t think exactly what they were called but what it is it says it’s an efficiency thing and when it goes bad, it doesn’t regulate the gas right and it can cause other damage to your car so anyway there’s four of them long story short they came the next day when they said they were as I said he came with just a basic cheap code reader not when that gets into details and they did it really quick I didn’t get to see any of the parts new or old. I hope the light stays off like I said cause I’d like them to do other work. I called him earlier because I had an issue and he hasn’t called me back. I’d like for him to call me back before I do drive my car For now it’s a three I hope to come back and leave it at five overall they were very nice guys and Do seemed to know that what they were doing. They did it pretty fast and seem like they have deal with these kind of cars before however, I’ve done my research myself and if I had the tools, I probably would’ve done it myself I got a long route ahead of me anyway that’s my review and yes, I did get a receipt, but I did not get anything saying about the warranty so when you see this I’d like for my warranty I’d like you to give me my warranty cause for $800. You could’ve told me a little bit more about my car. That’s what those expensive machines before that’s what I paid you for. I did my research. Please call me back.
