1994 Toyota Supra ProblemsUpdated Expansion Valve to Correct Leaks and Poor Performance
The AC Expansion Valve may develop a very slow leak or allow too much refrigerant flow which reduces cooling. Our technicians tell us that Toyota makes an updated expansion valve to resolve these problems if and when they occur.
At higher mileages (125,000+) the Engine Coolant Temperature Sensor may intermittently stop working, especially when the vehicle is fully warmed up. This can cause the engine to stall unexpectedly.
The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.
1994 Toyota Supra Questionshow to fix a 1994 supra manual transmission rattle? Any help will be great!!!!!! (1 answer)
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.
