I need some help

[Jimbo88]

Well my explorer seems to be having some problems with the gas milage. I have read around somewhat and think i might try using sea foam and see what that does for my truck. Right now i have been losing Mpg. I have recently add a flowmaster cat back, KKM air filter, and have had an oil change. I have cleaned the air sensor too. Any other thoughts on what it could be?? I used to be able to get about 16-17mpg easy but know its more like 14mpg. I just thought this was a bit odd. Any help or explantion would be great.Thanks

02 sensor I just replaced mine and it seems a lil better but nothing great. :thumbdwn:

when did you last do a full tune up... that usually helps gas milage greatly... I mean plugs wires oil filters tranny and general cleaning plus a normal once ofver for other broken parts

I just had the oil changed about 2 weeks ago. I have owned the vechile for about a year now. Thanks for the ideas. .
