well for one thing, when that little blue light on its pretty cold and i really wouldnt recomend revving the engine to much while its on cuz your gunna blow a head gasket cuz the gasket is cold and wont handle the pressure. anyway im glad mine doesnt fluctuate but i have an auto so whatever. my light pulley is kinda whinin tho maybe its my power steering belt. sry dont mean to thread jack lol

 

thats weird.. mine started to pull to the left too.. only 4200 miles on it. You geet what you pay for i guess.

 

my front left tires always seem to lose air faster. i dont know if that would have anything to do with that problem ^

 

my car has a slight pull to the left, but the roads here suck and I have 23k on it

 

My idle goes up and down also. I noticed it started when the dealer did my A/C upgrade on my 05. For the most part it only does it when the A/C is on but still seems to do it other times also. I asked the dealer and of course they said normal. If it was a problem the check engine light would of come on. Ya right.
