1994 Toyota Supra ProblemsCheck Engine Light Due to Restricted EGR System
The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
Our technicians tell us that it is important to change the coolant with factory coolant and replace the thermostat every 60,000 miles. This will help to protect the head gasket, otherwise the head gasket can deteriorate and be stressed to the point of failure.

its a 1994 supra 3.0L 6 Cylinder Turbo it happens after i drive for a while then when i stop with the clutch in it rattles and the throw out bearing is only two years old so i don't think that's the problem!!! any help would be appreciated thanks
I had my old supra motor replaced with a less used engine from Japan. Ever since the replacement the engine seems like it need to be tuned up or something. It does not idle correctly and the car sometimes seems like it is shivering while it is in park. What can I do about this problem?
Would like to know what the cost would be to replace my transmission.
