okay, so as the title says, my car hesitates (when it was running 
) whenever i'm cruising, maintaining a set speed, with my foot barely on the gas, and my boost gauge reading a vacuum pressure between 15 and 20 inHg.
mind you, now, this happens in any gear, at any speed, whether it be 3rd gear at 30 mph at 2500 rpm or 5th gear at 70 mhp at 3000 rpm.
realize, after i change out my rusty spark plug wires and plugs, this and many other fuel system problems could go away, but i was just looking for ideas right now.
...that and i could use some mo' posts in the old post counter

my vote is for TPS, might just need adjustment.
if you find it's bad, I have a brand spankin new TPS from mazda that I'm not using or ever going to use (have haltech).
email me if you want it, they're $179 new from mazdatrix, I'll sell it for $100. I had ordered it from mazdatrix without even looking to check the price in a large order of other things, insane.

I hope you install S4 Arms so you can replace the ball joints

can you confirm that i can use S4 TII A-arms on a S5 TII car? i'm tempted to go buy a set off the local wreckers and see if it will bolt up. seth said the mounting point for the end links for the sway bars are different. But if tha ti the case mazdatrix endlinks should solve the problem, provided they are long enough.
Can you confirm my observations? and ideas?
