Hello all,
I live in the Kansas City area and would appreciate a recommendation for a local Buick GN tuner/shop. I acquired an 87 GN a few months ago from an old friend who is in poor health. I know very little about the car but have been trying to learn more online. It gets poor mileage, has a very slight miss and seems to be running very rich. On a recent trip, the cc reading on the Scanmaster was a steady 254 at 65mph. I replaced the O2 sensor, and it now resets and climbs like it should, but in very large steps. It didn't seem to help much with the overall engine operation. I have no idea what tweaks my friend made to the ECU, etc. I know the engine is built with performance heads and a bigger turbo but other than that, I have no specs. My buddy has dementia and other health issues, so I can't really get any help from him. So, if anyone can refer meto a shop in the area that has some experience with Buick Grand Nationals, I'd certainly take it to them for diagnosis and repair. Thanks!
