My pt has been slowly getting worse gas mileage. It was at 21 when I first got the intake. Then moved to 20, then 19 when I changed my plugs and wires. Now it jumps between 19 and 20 off and on, and depending on how hard I acclerate. Last time I check it, it was at 15, thats after I used a bottle of high grade fuel injector cleaner. The Pt runs better and smoother then ealier but I have recorded that one bad MPG rating so far. Its into its second week without and I will see what I get this time around.
N/A with intake, custom stock box, double plat plugs & 8.5mm wires and some what spirited driver, 27000 miles.
