lunarhighway - so the problem is that you seem to get enough air while driving, but not at idle? how hot does it actually get in traffic? does the fan cycle on and off, or run constant as the temp continues to rise? are you certain the cars temps dont do the exact same thing w/o any grill block?

if the fan can run and cool ya off easy enough when stopped, i would think that everything is normal.

now i know lots of gm cars live by the airdam. for me, my 99 saturn sc1 sports a full grill block, and only gets what air bounces up off the airdam. temps didnt change at all when i blocked it, only difference was better mileage
