I have a 98 Formula.The promblem I am having is.
When you have the car in park and rev it to
2500rpm's and hold it there.The whole car shakes.
Now before 2500 the car is fine and after 2500
the car is fine.I am lost? <img src="gr_sad.gif" border="0">

Really only several things would be rpm/throttle position sensitive, i would check with some sort of monitor for flaky Maf readings or TPS glitches. Start there, you dont have aftermarket crank pulley do you?
