Kevin Bacon 5 Posted April 7, 2010 Lumpy misfiring when warming up usually indicates weak fuelling. Check / replace the blue temp sensor and go from there. Also clean out the idle valve in case it's sticking open. Quote Share this post Link to post Share on other sites

Toad 0 Posted April 7, 2010 Blue temp sensor is in the thermostat housing on the front right hand side of the engine, idle valve is the round thing plumbed in near the throttle body. Quote Share this post Link to post Share on other sites
