Bennington Auto Repair

2017 Silverado that was misfiring and having hard starting. We are doing an injector replacement and will be doing a walnut shell blast procedure on the intake valves. We will share that process next week. Don’t think the dealer is the only one who can perform this level of repair. We’ve got you covered!  

This is a really cool week for us here. Normally, we’d be headed to Kansas City for the Super Bowl of training for the automotive industry. VISION HiTech Training & Expo is going on, but in virtual format this year due to Covid. We will be loading up virtually on the latest topics for the next week! This is our commitment to our clients, that we are going to be competent and properly trained to service any vehicle needs and not only technical training, but business management and leadership training we are attending. Education and continual development is part of our company's vision. This ensures we will be around for a long time to take care of our great clients!  

One of the things that sets us apart from the crowd is our utilization of “Factory Diagnostic Equipment”. This is the same tooling the dealer utilizes. We have dealer level software for more than 10 manufacturers and dealer level software makes a world of difference in many cases. We invest a lot into having the best equipment and highest level of training to best serve you and your vehicle! We just acquired the latest Ford/Lincoln software to service select 2019, 2020 and all 2021 and beyond vehicles. We are your place to go for all of your vehicle needs!    

Pretty cool fix! So remember last week. We were working on this 2017 Silverado that had rough starting and misfires. It had two issues, the first was 3 failed fuel injectors which we showed you that process last week. The second issue was there is excess carbon buildup on the inlet valves. The inlet valves or intake valves are how clean air is supposed to enter the engine when it’s running. This engine and many other newer vehicles utilize a system known as Gasoline Direct Injection or GDI for short. This means the fuel injector sprays fuel directly into the cylinder. This is to help with fuel economy, emissions and power. With older engines, they utilized a system known as Port Fuel Injection where the fuel injector sprays ahead of the intake valve. With Port Fuel systems, the gasoline at the back of the intake valves naturally cleans them and it would be very rare to have carbon buildup on them. (See picture below). With 90% of GDI engines, there is no fuel at the back of the ... read more

How new of vehicles do we work on?? This is a 2019 Ford Ranger with roughly 10 computers reporting multiple communication issues with other computers. These are some of the most complex and difficult tasks to troubleshoot. We got this!! We have the skills, specialized equipment, and training. So the fun part... about to get nerdy again When dealing with computers not talking, I print out network maps and try to find a commonality. This vehicle is very complex and has at least 4 separate communication networks. Unfortunately, we had modules on all networks reporting issues, this is where it gets fun and you roll the dice. So I decided to start with why the blind spot detection radar units(side object detection modules)were both not online. I pulled the left tail lamp which houses the radar unit(see picture). I checked the communication network activity and signal with a labscope and it was present and looked great. I checked the voltage signal that turns the radar unit on and bingo, no ... read more
