I have been driving my truck around for over a year with the engine cutting out at 2000 rpm. No one could fix it. Even more wouldn’t even look at it. They would say “It’s just not something were interested in”. My plan was to just drive the wheels off it but emissions test came up and wheels were still on. So I took the truck in to see Ken at Greenlight. Long story short Ken fixed the problem of cutting out along with putting out three other codes. After two days work he suggested I try and get a waiver for my emissions because it was just going to be to expensive to keep going on it. It was the truck that didn’t want to be fixed. Every time he would fix a code another one would pop up. I left the shop with the truck running great. It still needs a sensor but that sensor has no bearing on performance. THANKS KEN & GREENLIGHT. - John M. (5 star review on GarageFly)
