This may have been asked/answered before, but, i couldnt find it anywhere on here. What are the major differences between a 1997 2.2 intake, and a 1996 2.5 intake? Can the 2.5 intake be used on the 2.2, or, arent they interchangeable? I put a 2.2 in a 1995 legacy sedan, and, it runs like crap, and shows a MAF (p0100), and evap (p0441) code. The reason i ask about swapping the 2.5 intake to the 2.2 is because, the car has the charcoal canister in front of the engine, behind the radiator, but, the new engine (2.2) doesnt have any way to connect to the canister, but, the old engine (2.5), does. The car wont maintain an idle, and constantly runs from around 550 to 2000 rpms, even after it is warm, so, im wondering if it is due to not having the canister connected, or, if the MAF alone would cause it.

the intakes will not interchange.

they are different.

with enough money and time you could probably do it,

but there is a better solution.

 

you need a 95 - 97 intake off of an ej22 engine,

they have the canister in the front,

maybe with EGR????

is your car auto or manual trans??

The only solutions i can see, none seem feasible. Either take the intake off the 2.2 and retrofit the vacuum lines from the 2.5, but, the last time i tried that, on another legacy,the car would barely run, find an intake from a 95 or 96 2.2, with the canister connections, which will be too expensive, or, figure out how to connect the canister properly to the current intake, which, i have no clue how to do. This is the first time i have ever had this issue when swapping a 2.2 into a 95-99 legacy, and, i have done at least 40 of those swaps. The car is an auto trans, and, so was the car the engine was pulled from. According to the attached pic though, one side of the valve is supposed to go directly to the tank, so, could i just run that line to the canister under the hood?

So the 97 has the charcoal canister in the back by the tank and the 95 has the charcoal cansiter under the hood if I understand you correctly.

 

It sounds like you need a 95 2.2 intake to match the car. I think 96+ all had rear charcoal canisters.

97 is when the canister was moved to the rear. I have 2 96 cars, one sedan, one wagon, both 2.2, and the canister is under the hood.

I beleive 96 outbacks all had rear charcoal canisters. I've seen two of them with charcoal canisters In the back. Could be the difference of the 2.5

One thing that really puzzles me though, there are no lines, other than the one going to the solenoid and map sensor on the strut tower, so, how does the solenoid under the intake connect directly to the rear canister, as the pic i posted seems to show?

The 2.5 intake i have, has the canister connections for a front canister, its the 2.2 i put in it that has the rear canister connections.

Throttle body should be the same. More likely that you are missing a connection on a sensor or one of your vac hoses is left open. usually look around with a flashlight under the passenger side. Make sure MAF, coolant temp sensor, IACV and everything is together and tight. Check your vac hoses to the intake, IACV, o2 sensors etc.

 

Charcoal canister tubes can be looped back on themselves or plugged. At this age, the canister doesn't really do anything anymore.

 

I've swapped dozens of motors and more often than not either have a bad idle or check engine light or something to tell me I missed something in putting it all back together. Double check, triple check, take a break and check again before throwing any parts at the problem.
