Engine bogs on WOT launch This problem first started about 2-3 weeks ago where "flooring it" off the line results in a noticable bog until about 2000-2500 rpms where the car accelerates as it normally would. Usually when I would go WOT when launching from a stop my car would spin the tires until about ~25mph. Now, with this bog, the tires don't even chirp from a stop. This bog only occurs from a stop if I go WOT, if I ease the pedal down or go ~1/2 throttle the bog doesnt occur. The car is perfectly drivable under all other circumstances and idles normally. I am very puzzled as to why this is happening. I've used the search button and found that others with the same symptoms were due to a vacuum leak on one of the PCV lines/ malfunctioning valve, or bad plugs and/or wires. I have checked all of the wires, but not the plugs seeing as they are new NGK-tr55's. I also looked over the PCV valve and associated vacuum lines and they all look intact. Any advice on how to better check for vacuum leaks, or suggestions would be greatly appreciated.

There you go.
Did you just recently start using sticky tires (eg.. Et streets?)

The 3rd brake light will affect the cruise.
