ok so i asked the other day about my bad bogging when i shift and what not, i check the air filter and cleaned it so that was fine, the maf and tps looked and sounded fine, so my last guess is its under the car as in the exhaust, getting my gears installed sat they have a dyno there and i coudl get 2 runs and a a/f check for $35. coudl that be able to show where my prob is and poss fix it?
