professorbob Intake Join Date: Nov 2007 Location: Lavonia Posts: 49	Engine Stopping update Thanks for the Link, I will check out the HAC High Altitude Control values. After extensive reading at this site www.autoship101.com I learned there is a relation with the brake light switch and the engine control. I have a panel light that indicates there is a problem with the brake lights. Just wondering if you know which fuse controls the brake light circuit so I can remove it. Am thinking that the ECU may be affecting the fuel cutoff because it thinks that the brakes are being applied. I plan on purchasing a replacement Throttle position sensor as well because of the fact that it is out of spec. I am hoping this will also improve the starting on first try rather than the present 4- tries. Thanks for you help. Robert
