In the last couple weeks I questioned my wife on her gas mileage (got a deer in the headlights look) and asked her to start logging her mileage between fill-ups. I haven't had a chance to fill up again, but on this last tank, she has right at 200 miles and less than an 1/8 of a tank left. Once I fill up, I'll know where it is, but it looks as though this tank might come in at about 13.3 mpg. So she is out of town this weekend so I figure it is the perfect time to tear into her car a bit and change plugs. The current plugs have about 40k on them (non-tuned) and we replaced by the dealer when we were troubleshooting (what was found to be the cracked piston resulting in a new short block) and are the 534's.When I pulled out the plugs first thing I found was front drivers side coil clip was broken. It seats and stays in place, but the plastic retainer piece is gone (note I have yet to document a true misfire while diagnosing this issue, so I'm very hesitant to say this is causing any issues). Guessing the dealer must have broke it at some point because up until this point, other than oil changes, no one else (including me) has been working on this part of the engine.Coils looked good. No oil on any of the coils. Plugs came out good. Looked pretty decent to me, but some of you guys are a little better at reading a DI plug. All had gaps of about .031 (one I could squeeze .032), so I didn't have massive gaps that I was reluctantly hoping for so I could say with confidence that I found the root of my problem.Anyway, here are a few pictures of the plugs laid out according to how they were installed. Top of picture is passenger side, right side is near firewall (sorry, don't know cylinder numbering on this engine). What are your thoughts on the condition of the plugs? Anyone think I found a cause of the random stumble and/or recent loss in fuel mileage?Firewall sideFront sideAlso, while I was in there I pulled the intake tube off near the TB and used the dipstick to see how much oil was in the IC. This is with the car flat on all fours. Guessing I need to do a little IC cleaning.
