I've been searching the site for about a week now, trying to research the problem I'm having with my daily driver, a Franken-MY '04 WRX wagon.
First off, I should explain that I drove the car thru some standing water this past spring during the flood season and seriously hydrolocked the orig. engine. Enough so that it bent the valves and trashed just about everything under the hood, save the battery! Fortunately for me, my insurance co. covered all of it except the $200 deductible, which landed me an '03 motor/turbo with 39k on it. Since the production date on my car is June '03, they went with this.. I didn't have much say in the matter unfortunately, but I was getting an engine with 1/2 the mileage than I had before so I didn't put up too much of a fight.
That is until now. I don't know exactly when, my guess is about 2 weeks ago, but it seems now that I can't get the car to reach full boost in any gear (MT). The most I can eek out of it is 7.25lbs. It's purely stock under the hood sans a K&N panel filter and a cat back scooby sport muffler (love the grrr baby!). I've checked to make sure my wastegate pill is in place, the hoses all seem tight, and I don't hear any obvious hissing or exhaust leak under the hood when it's at idle. I'm going to consider doing some soaping around the up/down exhaust gaskets when I get home this eve to see if any bubbles show, but I was hoping someone may be able to suggest other things to check.
Edit: I also wanted to add that I tried some of the valet settings (mashing the gas down while the key is in the ON position and turning on the defogger? I did some rain dances while doing this as well in hopes that our drought would end too ) and I also disconnected the pos. term from the battery for about 45 min.
So, please!! Help me in my efforts to keep this car out of the (st)ealership!
