Interesting, that would explain everything if that were the case. I'll have to check.

I still don't know what's wrong,
Tuned map: 68 g/s Stock map: 80 g/s Stock map minus some fuel: over 100 g/s (still feels just as slow) This is outrageous. My 3500lb stock baja 2.5i with 257k miles is a lot faster than my newer 2.5i, both 5mt. |

Timing off? Check your belt. Also did you ever check the cat being clogged?

Can you run learning view with your car? Check iam, knock and a/f learning. Did the mechanic check compression or do a leak down test?

IAM is a perfect 1. No knock is occuring. I was never able to use learning view, my laptop just doesn't let me for some reason. Not sure if the mechanic checked those things; all I know is that my engine is not misfiring at all.

The key symptom is the fact that just tapping the throttle is the same as WOT. It's like the engine is trying to tell me something. It's saying "no, I don't want any more air" or "help me, I'm choking."

Fuel regulator issue?
What about pulling the intake off and verifying the dbw has full travel when given 100% throttle? Also +1 for timing belt jumping. It won't always throw a code but still run like crap. MT is more susceptible even with the belt guides. Last edited by mavstang73; 01-21-2014 at 09:26 PM. |

A mechanic actually checked the timing. I took off the intake with the car not running but with the key forward, and the throttle plate opens all the way. Not sure if it would make a difference if I tried that again with the car running because the ecu might not be allowing it to open all the way.

I can't see how it would be low compression, unless I suddenly lost an equal amount of compression in all four cylinders causing no misfires. I've had this low power problem for six months now and it hasn't gotten any better or worse. I took a 300 mile drive from Maine to NY yesterday cruising like 65-75 averaging 31 mpg. My car was purring like a kitten when I got there, except it sounded like my exhaust leak got worse in my header mid pipe.

I may have made a discovery about my car's problem today. I had a huge vacuum leak temporarily after doing something stupid (forgot to bolt up the EGR valve after checking it.) As I was driving with the vacuum leak, the car actually felt a lot faster, first gear felt powerful, and it seemed to rev quicker. I think it was the extra air intake through the EGR valve opening that gave me this extra power. Maybe this means my intake really is restricted? Maybe the butterfly valve?

Sure sounds like it to me.
There is something odd going on with your intake track. If you found a tennis ball in there it wouldn't surprise. |

You mentioned you cleaned - not changed - the air filter. Any chance you coated it with a hermetic silicone paint?
Also, what's your vacuum at WOT? |

No, believe me, the air filter is as clean as brand new. I cleaned it twice. Vacuum at WOT is 0.15-0.2 psi, which suggests that the throttle plate should be opening fully, unless my map sensor is going bad?

You sure you don't have TGVs? Look at you map in romraider and you can see if your tuner deleted the code.
It happened to me the tuner sent me a base map from another car and forgot to undo the tgv cel delete (I still had tgvs) and when one of the motors died I couldn't figure out what the hell was going on but obviously eventually figured it out. |

You should be able to visually observe them. They will be located near the ends of the intake runners just before the port/head. Without them you will see a smooth transition from the round runner to the triangle shaped port cross section and nothing in the runner casting except an injector and maybe some bosses for mounting fuel rail, etc. With TGV there will be a small servo motor mounted to the side of one runner per bank. You can google images search "Subaru TGV" to see what to look for.
I also know that some n/a ej engines had TGV's. Maybe it was a pzev thing to help fuel/air mixing? |

I don't see any tgvs. The intake valve bolts right onto the engine with nothing in between but my phenolic intake manifold spacers and the gaskets. I'm all out of ideas.

Just for the hell of it can you take some high res under the hood shots and post them here?
Like some from each side and the front and as close as you can to an overhead? Maybe we'll spot something out of place. |
