[QUOTE="CHRIS_D, post: 403208, member: 7720"] Help, I recently switched to the NGK CR8EIX Iridium (sp) plugs on my 2007 with 8500 miles and my mileage went from an average of 40 MPG to under 33 MPG. Yes, I have run a few tanks of gas, so I don't believe it's the gas. Anybody know why this may of caused such a big drop in mileage? I did go back in and double check each plug to make sure the color and gap was correct. I also check to make sure that I didn't some how disconnect a vacuum line. I couldn't find anything wrong. Also when I originally replaced the plugs I also sync the throttle bodies, which I have done before without any problems. However this time, I didn't replace the wire clips that hold the rubber caps on because it's such a PIA. If it's not plugs is it possible to get bad gas mileage if there is a small hole or leak in one of the throttle body rubber caps (where you connect the sync tool)? Has anyone come across this problem before? Thanks in advance!! [/QUOTE]
