So I took my car down a toll road yesterday that's speed limit is 75and of course I do the normal 5 over cruising along at 80 I got to switch lanes and the fiero starts to act like it's going to fish tail so I let off the throttle and ease back after I almost crapped myself.
Not sure what I did I have got my garage cleaned out yet but I plane to stick it in for a while (Have some other things to do. But now anytime I get above 65-70 it gets really squirly and scary it also does it now I've notice when I mash on the gas.
What should I look at and what are some goo upgrades? I was looking at the zero lash sway bar link because I always though the steering was a little to loose. Give me some ideas please withought digging to deep in my pockets lol.
If you have replaced suspension parts get it aligned. If you haven't replaced parts check out out everything, replaced what is loose and then have it aligned. I have a 1986 GT 5 speed and had issues after replacing suspension parts. The rear is more critical than the front. Just changing rear rode height (I've got coil overs) change the camber and toe in. It would pull one way whe accelerating and another when decelerating. Getting an alignment straitened it out.
Most of the time the problem is either with tire pressures or the rear tie rods being worn out. Even a hint of looseness in the steering axis of the rear wheels will give squirrely handling especially when changing the load (accel/decal) on the tires.
Jack up the rear of the car and grab your tires at the 3 and 9 o'clock positions and wiggle hard... any play is not good and is a sign of a worn tie rod (most likely), or a worn bearing (but only if play is also felt when wiggling the tire at the 12 and 6 o'clock positions) or worn control arm bushings (least likely).
