Contact OLT when you call or email them. Hes is the one who did mine. They needles come with a lifetime guarantee. Very good people and a quick turn around.

What color is your interior trim? There are several places.

I would check the common things first, maybe the Mass air flow sensor, plugs, wires, fuel filter, and I am leaning towards a ECU. Very common on these cars to cause weird problems as you are describing. A used one is around $50 or so.

There are several problems to be aware of.

1) Lower control arm bushings, check for play, replace with Daizan bushings from TM Engineering or replace with Supra 94-98. Bolt on.

2) Lower ball joints, see if boots are busted

3) Power steering leaking under tank or main hose, will cause alternator to go out

4) Cracks on the radiator overflow tank

5) Cabin vents crack from temperature change, hot and cold

6) Blacked out LCD on your climate control, can change for aftermarket one on Ebay for 125

7) Needles and back lighting goes out. Contact Lextech.com or Lexls.com for a DIY

8) Door hinge sag

9) Craks on upper door panel where you arm normally rest while driving

10) Window regualtors break, can be fixed easily

Im sure they are more but these are the most common ones. Make sure you do the maintenance, timing belt, plugs, water pump, etc.
