first tacoma build questions

What's up taco world! I just bought a 06 trd sport double cab with 80k miles for $16000.... I shopped for a while and for the condition and price compared to all the others I looked at I thought it was a good deal if any one wants to comment or speculate on my purchase I'd appreciate it. I've started to do a few small mods to it and I'm loving how its turning out. I've just got a few questions about abnormal shifting which is very inconsistant and some allignment/ballance issues which inturn makes me wonder about my mpg. My truck never changes gears at the same rpm and doesn't seem to want to go into overdrive by itself.... Need help on that one.... And I just got a set of 20" x d series wheels with mastercraft tires all freshly ballanced and rotated and I still get a wobble at about 50mph and I think all that is making me get bad mpg. I also jus had a check engine light pop up so I put the computer on it and it gave me codes for air fuel sensors so I cleaned everything from the intake to the throttle body and reset the ecu. The light was off for about a day or so now its back on. Any ideas guys?

 

Wow, Tacomas sell for a premium price where you're at sounds like, but $16K is too high for not only an '06, but it sounds like an '06 with some issues, the mileage sounds about normal, not trying to rain on your parade bro'... Hopefully the shifting issue is going to be a not-so-expensive fix...

Welcome to TW also....

 

thanx for the input man.. Yea i hope it wont be a big or expensive problem either. Im going to get the trans flushed today and see where that leaves me.
