I recently bought a 1992 toyota land cruiser. It was a pretty clean one owner however do to the years and how old it is of course it had a few tweaks. One of which was that it was getting terrible gas milage and it was running rough. I went to 3 other automotive repair shops, of the three one was the toyota dealership/service. They told me straight up, "nothing worng" well I knew different and once I got it to simmons they to knew different. My 92 land cruiser is running show room perfect. Thanks dean and thanks to all your wonderful staff 👍👍👍
