I have an 88 tc and it just began to idle irraticly when idiling it will go from 1000 to 200 and kick back up and comtinue to do this. and sputter when driving and it has been getting worse. I changed the plugs, wirs, cap, rotor no luck. It seems to not be as bad when it is cold but when it warms up it gets worse. Also the turbo wont go over 8-9 psi---why. No strange sounds coming from turbo or fuel pump.

Have you pulled the codes? See the FAQs for info on that. Also check all hoses for vacuum leaks. Keep us posted
