hi mates

lately my car started to not be as punchy from a start as she was before,

when i'm stopped at a redlight then on the green i hit the throttle hard , it kinda boggs,

it jumps ups to about 1500 rpm and then ,slower than usual , it accelerates

what my baby's proplem

Vaccume leak, Clogged up IACV or maybe knock sensor going bad.
Test both units and look for cracked hoses.. Ive had similar problems and got some improvements with these test. Replaced all vaccume hoses
Good Luck... Maybe someone has an answer for this. Elusive and mysterious source cause for bogging car with bad mpg.
