After about two hrs of stop and stop traffic thurs. my 97 brighton w/ 2.2 and 5mt, now has a higher idle the when I started the drive. It now idles @ 2k rpm until warmed up for a long time and the it idle about 1500 rpm. I had always felt it was a little slow returning to it's normal (about 800 rpm) idle when you clutched it in the past. Could this be a dirty IAC like the other post?

Man I reallywant to see more offical documentation on this. The numbers and math just don't make sense. as circ. = 2*radius*pi(3.14 for this) .25=2*r*3.14 r=0.04 a change of .04 inches in the distance from the hubs center to the road will cause binding? Next time I get a real acurate tape measure I'm going to find out how much those tire defelct with 150 lbs in the seats. I'm not trying to attach anyone. Just I think more has to be looked into these numbers.

I got new tires on my 97 brighton wagon. I know that the factory recommends 32 f/ 30 r, in the tires that came on it from the factory. I am also a little unhappy with my gas milage. on with the question.. The new tires state a max. pressure of 44 psi. What kind of pressure would work better. Keeping a precentage difference between front and back, or a 2 psi difference?
