ok so last night i unplugged the front o2 sensor from the wiring harness and the acceleration gets better, and the exhaust wasnt as loud, after i plugged it back in the bogging came back. my gas mileage isnt suffering to much i would guess im getting around 20mpgs just from what i can gather because my gas gauge doesnt work. it goes up and down everytime i out gas in it. but thats a different problem. so heres what its doing. i accelerate theres not alot of power coming off the line, as in if i punch it it doesnt spin the tires almost at all. if im going down the road and i need to pass i hit the gas and it takes a second to get up and go then boggs down for a second. then snappes out of it and gets up and goes like its a perfect car. if im driving normal and its bogging pretty bad i floor it and it boggs then it accelerates better after it goes up a gear.
