acdii Report post Posted January 10, 2013 So far now that I have the car back with new plugs, I have seen an improvement in MPG. My fill last night was 38.9, granted I drove it very slow, but it still an improvement. What is making me think it may be resolving is this morning I drove it more like I usually drive, and didn't pay attention to how many revs I was doing, kept up with traffic to an extent, and got 41 on the dash. Keeping up hope that it may have just been a bad set of plugs all this time. 3 coach81, lmp180psu and jeff_h reacted to this Quote Share this post Link to post Share on other sites
