[Supras] Problems...

[Steve Michael]

87?  If it's not an intake leak (inspect the intake line from filter to Throttle body),
then it's probably the wiring around your CPS. 87s are notorious for having the wiring go bad, 
and the replacement harnesses are getting pretty scarce.

Start by clearing & running some diag. codes from your ECU. While you're at it, it pays to do a fuel injector flush, 
clean gas, and an inspection of your ignition system (wires & plugs). 

As with anything, tackle the cheaper stuff first before replacing a perfectly good (albeit small) turbo.

----------------------------------------------------------
I took my 87 supra out the other day. Went about 8 miles and parked it at the store. I came out, started her up and started to leave. As soon as pulled out into the street and gave it some gas she just putted rapidly until I got over 3000 rpms. Shifted into 2nd and she did the same thing. She runs fine when its in high rpms. Then she putts when I boost anything over 5 lbs. I know the turbo was going out but would that effect the car at low rpms? She also has a rough idle. During idle it will miss here and there. Its not a steady miss though.

Any idea what it may be?
