Have your mechanic check the Idle Air Control (IAC) motor and the Throttle Posistion Sensor (TPS). The IAC motor is also referred to as the Idle Speed Control (ISC) motor. That motor is resposible for keeping your idling at a constant RPM when your car is at a stop. Your TPS is responsible for letting your car's computer (ECU) know how far the throttle plate is open. Your ECU uses this information to tell your fuel pressure regulator and injectors how much fuel to put in your engine. If you find that either your TPS or IAC is malfunctioning, replace them. Along those lines, also check your Base Idle Setting Screw (BISS). It's located at the top of your throttlebody.

Worn out clutch plates can also cause the problem, that you are experiencing . Kindlu get the same checked

code p0303 refers to cyl 3 misfire detected ===causes engine mechanical fault--wiring--ignition/fuel system--injector--ECT/MAF sensor--ECM
code p0316 refers to misfire detected during start up --first 1000 revs===causes --engine mechanical fault--wiring--ignition/furl system--injector
the common fault cause is ignition/ fuel system and injectors so I would be checking fuel pressure and injector systems for clean and wiring connections are good especially on no 3 injector.

2005 voyager runs great when cold but as soon as it heats up it won't go over 3 thousands revs.

You have a cracked head, are they are cast, when cast metal is cold it shrinks, now I am meaning really cold outside like almost freezing, and when it gets hot the crack opens, don't know if they are cast or aluminum though, but that is one of many tthings it could be. I wish I could be alittle more specific for ya

check the vacuum lines on the engine.sometimes these will crack or develop a small hole or break and it will **** too much air in the engine causing it to act that way.

Subaru impreza 2l turbo, 1994, starts fine and

your spelling is horrid.   I think your boost control valve or pop-it valve is defective.  Also try a basic tune up with plugs and filters.

sounds like coil pack, when your coils break down due to age the spark then jumps from the side of the coil to the alloy head, i would recomend taking the coils out and getting them tested to be 100%.
