So I'm trying to help turbo meow(frank) out with his car.
The original 2.2t crapped out and we found a low millage 2.2t motor
with 32k that had been in storage for a long time but. The motor it self will start and stumble to idle. once it stops boughing out it will race to redline.
The Iacv and tps have no change if you try adjust it, I have no idea.

Did you swap over the sensors from the "crapped" out motor?

They may be in better condition then the one in storage. You may want to try swapping the coolant temp sensor.

I have no clue all I did was source the motor. He did the swap but I'm thinking he didn't. Were going to swap the intake manifold an all the sensors from the old motor to the new one, hopefully that will fix it.

If the throttle butterfly is closed(idling), then it shouldn't get enough air to go redline. Are you sure there aren't air leaks somewhere.

I was only able to look at it breifly but the throttle body was closed and then it would just rev and wouldn't stop unless we pulled the key. Im going to try to get down to it and swap the intake an make sure it has new intake gaskets. its the only thing I can think of.

i am the one that helped turbo meow (Frank) with the EJ22T swap. well the motor was from an auto and is going into a manual. i am not to familiar with the Subaru are the sensors different from auto to manual? or are they the same? we did not use new gaskets as the parts store did not have it in stock. so i checked the old gaskets and they were still good they did not any cracks and was not torn. as far as i know there are no disconnected vac lines and everything was connected properly but like i said before i am new to Subarus so any help would be greatly appreciated thanks you. and thanks Brian for posting this thread and for all the help

No mechanical/sensor differences between 4EAT and 5MT... just a few things you need to do trick the ECU to think it's a manual now. Well documented here: http://www.surrealmirage.com/subaru/swa ... rical.html

well we are using the original 5MT ECU just that the motor came out of a 4EAT.

also the car will not idle at all the car will just die. when Brian says that the car will rev to redline it will only do that when you give the car some gas to keep it idling

What happens if you unplug the connector from the IAC valve and try and start the car?

not to sure as the car is not with me at the moment but i will be going over there next weekend most likely so i will try that and see what happens. im sure that it will not change anything as i believe the IAC motor is bad. we do have the IAC from the old motor as well as intake mani. so i will first try to replace the IAC motor and if that does not work then i will install the old intake mani. if that fails as well we have the cam sensors and other mis sensors that i will change over. and if that does not work then i will start looking over the wiring harness for cut/ bad wiring. i will update when i have done this. anyone have any other suggestions before i start this next week?

also i forgot to mention that when you press the gas pedal it has a very big delay. when you press the pedal it takes about 2 seconds before the motor responds, then it will climb to redline. could it be a combo of the TPS and IAC not working? also does it matter if the throttle cables are reversed/backwards? and there is not a cel light on when we first started it up and noticed the problem there was a cel but that was because there was an injector unplugged as the clip that holds the connector on had broke off.

i have been searching on here to see if anyone has had similar problems and i cant seem to find anyone having this problem.

What do you mean the throttle cables are switched? You're using the cruise control throttle cam for your throttle pedal? If so that may be why your experiencing the delay.

The throttle cam is smaller, and you have to take up the slack in the cable.

What codes were stored? Just that injector?

well what i mean by the throttle cables may be switched, is the way the cables are hooked up to the throttle body. like the throttle could be switched with the cruse control cable when connected to the TB its self. i dunno ill try that as well and see if it changes anything.

as far as i know its just that injector code. when i get back over there i will try and pull the codes. but i will not be able to clear the codes to see which ones come up new if there are any new codes as the motor will not idle.

so when i am able to get over there i will first pull the codes. then i will put the old intake manifold on with the sensors from the old motor and try and see if the car will run. if it does not run still i will go about removing the other sensors off the block and heads and try to see if it will run. if not then i will look over the wiring harness for any cut/ disconnected wires. other than that i am not sure what else to do.

yeah i dont really know what is wrong with my tleg but i am going to just take it to a shop hope they will help me out but thanks anything else you might think of let me know
