yesterday i spent about 6 hours just doing some routine stuff plus rust repair and what not. anyway i put my stock AFM and air box and all that back in to get some mileage back with the new gas prices, but before i did, i took a rag to my throttle body. lots of gunk so i pulled it off and was amazed at how much absolute crap was built up on the back side of the TB and especially in the upper intake. i could run my finger inside the intake and coem out with a half inch of black gunk on it. surprised an engine can even run with all that in there. i really recomend everybody pull their tbs and clean the heck out of them and as far as you can reach into your intake.
