Switch to regular 87 octane for high altitude driving Posted by Notnoel [Email] (#23) [Profile/Gallery] (more from Notnoel) on Sun, 13 Jul 2008 07:19:16 In Reply to: classic 900T in Colorado- perfomance at 5000ft???, drupchen, Sat, 12 Jul 2008 11:14:48 Members do not see ads below this line. - Help Keep This Site Online - Signup |
You are running rich at high altitude. Less O2 with a similar mixture equals engine running rich. Clean your plugs, they are probably carbon fouling. With regular gas, the ECU will have less trouble leaning out the engine to the appropriate mixture (will be closer to being within tolerances).
