Some days it won't use any gas some days it will use gas like it's a V8, did full tune up haven't done the fuel filter yet, that's my next check. Any possible solutions, oh yeah it also idles rough sometimes but others it doesn't, but driving it it uns smooth. HELP!
Yes, a leaky exhaust can cause this condition. If the hole in the exhaust is near the oxygen sensor, the exhaust could be pulling in air (with oxygen) which tells the O2 sensor that the fuel mixture is too lean and will increase fuel to the engine. This can cause rough engine (too rich) and will decrease gas mileage.

Sounds like you could possibly have a bad injector dumping fuel would cause it to do this there are a couple of different things that could cause this best thing to do is put it on diagnostic machine because i could list things for days and it will cost you a lot of money to guess fix this problem. should not cost very much to have diagnostic done and most shops if they do the work will not charge for the diagnostic

Haven't had any codes read, not sure what I should do.
I do know my exhaust has a hole or something in it but haven't had time to get it checked would something with the exhaust cause it?

Have you read the error codes to see what the ECM indicates? Could be an oxygen sensor or, many other things... Charlie
