So I have been a member of this forum for some time now and have yet to introduce my self. The primary reason being that I didn't have anything to write, when I joined back when I did I was on the verge of buy a WRX but that fell through and that was pretty the end of that venture. Recently though, things have change. i posted this over @ another Impreza forum and thought i would post it here too considering i consider my self to be one of the family now. Enjoy.
Hey there guys and gals,
I am the new kid on the Block. My father and I recently acquired a 2002 Impreza WRX, with a 5 speed manual with the Check engine light on. He and I both love the car and have loved them always. I my self have been into the Impreza since first watching it in rally races back in 1998. one of my all time favorite Imprezas will remain the 2000 Impreza STI RA. We purchased the car used with 140,000 miles (mint huh?). The car does have a stock top mount intercooler, a "different" turbo what ever that means, an HKS BOV, AEM CAI, Aftermarket black wheels, what we believe to be a turbo back exhaust (catted), aftermarket up pipe, and a "6 puck bronze clutch", stock spoiler, factory installed accessory Boost gauge.
The WRX had what I measured out to be a 3" drop (front ride height of 12.75" and rear of 12.55"), measuring from top of fender to center of wheel center cap. Versus "stock" ride height specifications. The car handled horribly, bounced all of the time. Very dangerous, we were told that the previous owner lowered the car the cheapest way possible. He cut the springs (wtf) so we ordered a cheap set of 1.5" DNA brand drop springs ($75) from eBay, (I know with a proper set of springs and shocks the car can and will drive even better but we were low on cash and needed an immediate fix) and installed them our selves. Bingo, drastically better handling instantaneously.
Next we scanned the codes that the check engine light put out, 1 code came up. P0031 (front O2 sensor) alright so we'll handle that soon enough we thought. Next the Upper rad hose sprung a leak. Bought a new hose, some coolant and voila fixed. we continue driving the car for a few hundred more miles, but the car would not run well at all, when you got on the boost the car seemed to "over boost" and putt very harshly. So we decided to change the spark plugs and see if that helped. After the old plugs were removed we found them to be crappy AC Delco's, We replaced them with NGK Iridium IX plugs, test drove it and once again Voila we were driving a completely new car. Though it still seems to hit a "fuel cut" when WOT at the upper RPM's of the 4th and 5th gears.
Next we jacked the car up again to change the oil because it was darker than Tar. Chucked the crappy fram filter and replaced it with an OEM subaru filter. New model OEM Magnetic Drain plug and Walmart 5 Quart jug (4.8 qts of which we used) of Mobile 1 5w30 Full synthetic motor oil and she had new blood running through her veins. While we were were changing filters we decided to change the fuel filter as well with an OEM unit :-)
So at this point we are very tired of seeing that damn yellow check engine light constantly on, so we bite the bullet and purchase the O2 sensor from amazon. A Bosch unit on sale for about $97 dollars (great deal huh?), get it in the mail a lot of PB blaster and some time later we were done. Checked the codes again before we cleared them and now we have 3 codes up (wtf?). P0031 (front O2 sensor), P0546 (EGT Sensor), and P0244 (Turbocharger wastegate solenoid A range/ performance) <~~ huh? To remedy the EGT code we did the 2.2ohm resister mod and solved that problem, I cleared all of the codes and the relentless check engine light was finally out. Hooray...
Just took the WRX to Glanzman Subaru today to handle a couple of recalls and was told about this site from the parts guy. So i joined and here we are, proud new members. Thanks for taking the time out to read this.
