Ok guys, Im still working on my full tune up. HEHE, well, I recently replaced my spark plugs and wires, and took the intake plenum off, and cleaned it out, replaced the gasket, and sprayed some throttle body cleaner down it. WEEELLLLLLL... for some reason after I did this [I disconnected the negative battery cable, kause i was dealing with the ignition] my check engine lights never came back on [ive had a code or 2 for like 2 months.] ... u have to know that the code was for the "evap purge system somthing-or-other" aka, vaccume system. and it started after I put my cone filter on. Now, it overheated a lil more than a month ago, and it got a new pcm and new head gaskets. when this happened, the dealership told me it needed a major tune up, and I told them id take care of it. So im still taking care of it... ok, well no error codes anymore, but those codes were reguarding the vaccume system !?! .... jus wondering if i should worry?
ok, on a different subject. My gas mileage isn't up to par. umm, short history, ive recently changed the oil, spark plugs and wires, and ran a full bottle of injector cleaner. after all this, even though the code is gone, i still get only around 300 miles to a tank [reset trip meter at each fill]. 2 things that might be culprits... I put the air box back in when it went to the dealer [didnt want them saying anyting to warranty company bout intake] and havent replaced it with my cone yet, mainly kause im waiting to move my pcm and evap can so i can put the cone down there where its cooler. OH, the air filter is probably pretty shitty, screws are stripped, havnt touched it since i got the car [currently 19k ago]
the other thing might be the fuel filter... ergg, Im not gonna attack that right away, but i guess ill have to do it next oil change.
ahhhhhhh this was a long post. thanx for reading through it, and thanx for help/opinions.
