Based on the image you posted, to me, it seems like only a small increase in air flow would occur cause it's rather thin. What does a limp mode do? You have to put it on at noon to 10 o'clock and then rotate clockwise to 3 o'clock, then screw her down. Look up your code definition. Its also kind of a marginal increase in flow so that's why i said that if you not necessarily on the hunt for hp everywhere you can find it I would just leave it be. I bet the heat isn't so good on it. I read on another forum that the flow divider plate is a bump stop for the valves.
If you are unsure of any abbreviations, check out the acronym list by clicking on the link at the left. Other than that i woulda jus low it ya man. Still driving car for now. Subaru's thought is that if they decrease the number of air going in at idle, it will burn less fuel therefore less emissions? Or maybe the motor that actuates the valve shaft is not operating? Ended up re-mounting the sensor incorrectly see below which caused the car to drive even worse. We have a large number of resources to help you repair the problem.
It may be simply a faulty electrical connection or bad sensor. This tells you where to start testing. Yes the sensor is pre-loaded. Below you will find the most complete list of Subaru trouble codes available. When they're not there, there is no restriction in the intake manifold so air flows freely into the engine. Yeah i think it closes whenever you come off throttle and at idle.
The connector may have a removable cover. Really tough to get at these screws. Dropped screws and sensors many times. But the emissions thing a mess me head. Could the valve be stuck in the closed position? Can I do this delete myself? Or it could be mechanical. Kit actually included two sensors and two motors.
I get how it works. They basically do the same thing. How much damage will I do if the p1088 code is permanently tripped? So please read our and when you're ready jump in! « Last Edit: June 25, 2009, 05:01:28 pm by Giggs » Logged It's on the Intake and controls emissions? On cold starts the butterfly valve opens slightly to create a 'tumble' for the air going into the cylinder thus the name tumble generation valve and this reduces emmisions on cold starts as according to subaru. So I guess I'm just talking to myself some more. Or when u also come off the throttle? Simple little trick if you think they're sticking, which makes sense considering the mileage.
When the engine warms up the valves open and stay open. What and where is this valve? After the weekend of testing and thinking. One major question…how long can I drive like this until I cause other problems? Took it by Subaru and they scanned and…. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there? Subaru's thought is that if they decrease the number of air going in at idle, it will burn less fuel therefore less emissions? In my personal opinion - yes if you're looking for horsepower everywhere u can find it. Anyways figured out how to remove the sensor while only removing the turbo heat shield.
But the emissions thing a mess me head. . They will provide valuable info! If there is a link to a specific diagnosis strategy for the code then follow that and start testing. There was no stuttering, surging, knocking or pinging. Remember, these are manufacturer specific codes only. This creates a swirl in the air fuel mixture the engine also receives less air and the engine operates more cleanly which theoretically reduces emissions through the cleaner combustion.
So I guess I'm just talking to myself some more. You should be able to find just the motor for cheap though as a lot of people eliminate them. These are listed in numerical order for easy searching. I also replaced the Turbo last fall so maybe bumping it caused the damage. Really just completing the story so that anyone in the future that has this problem can find this thread and hopefully learn from it.
