March 31, 2008Hey guys. I just attempted the TPS adjustment on my work truck, a '99 F-350 with a V-10. The truck immediately started idling at 3,000 RPM. But, the adjustment didn't really do much. The voltage was at .938 when I started, and I couldn't get it to go higher than .946
But, stupid me, I ran Sea Foam through the brake booster line right before I started messing with the TPS. I don't see that affecting anything, and I did make two short trips after the sea foam, and there was no noticeable change.
I can't see the sea foam causing the idle problem. Help!
