Supercharged 2 Posted September 3, 2008 The adjustment is on the metering head but I really wouldn't touch this unless you know what your doing... It's more likely something else is wrong or you have a sensor down, you need to get it on a diagnostic machine Quote Share this post Link to post Share on other sites
