I know it's hot out but something is seriously wrong with the acceleration in my 05 2.0 Duratec. Just for fun I timed my accel time tonight and it took me 16 seconds to go from 0-60 at a stop light with a slight decline and pedal pressed all the way down. 9 seconds to go from 0-30. This was with the AC turned off. I am at a loss as the were to start troubleshooting this issue and hopefully someone can point me in the right direction.
I put the Stealth CAI on last week and thought I noticed a slight improvement at first but nothing to write home to mom about. I recently changed the plugs, but it had this accel issue prior to that. Cleaned off the MAF sensor when I put on the CAI as well. Also, my last tank of gas only got me about 23 MPG... Also, when the air is on and I punch it, my AC temporarily blows warm air until I ease off the gas.
Ideas that are rolling around in my head that might be up are: Alternator going bad, coils/boots are going bad, fuel pump going bad, vacuum line leaking/plugged, exhaust leak/restriction, throttle issue, PCV going out... really am befuddled though... I really don't want to take it to a shop to find out it is something that was right in front of me... Any assistance will be greatly appreciated.
