I have been a WRX fan for many years. I used to run a sweep vehicle for the SCCA Pro-Rally races that were held in upper Michigan. I've been looking for an early 2000's WRX for a few years, and finally found one... I just purchased this car on Friday night (2/3/2012). It seems to run ok when I took it for a couple of test drives, although, I questioned the smoke out the back after driving it. The amount seemed excessive. My friend and I couldn't find anything obviously wrong with it at the time, so I bought it and brought it home. I commute about 35 miles to work each day. As I drove it to work yesterday, I lost power and it went into fail safe mode, not going above 2500 rpm in any gear. I took it into the Subaru dealership to have them read the codes and look it over. The issues they found are listed below. They just called me today with the report. I feel stuck and would appreciate any input! I've only owned it for a few days, and I feel like I've been scammed. There was no bill of sale or anything. I am not sure how to go about even fixing it at a price that I can afford. Thank you, Leanne.
According to Mat from Grand Forks Subaru Service Department:
1. 4 trouble codes that were found:
P1507 Idle Control System Malfunction (fail safe)
P0420 Cat Efficiency (don't worry about this one according to Subaru service dept)
P0304 #4 Mis-Fire
P0302 #2 Mis-Fire
2. Needs an MAF (mass air flow) sensor to fix the idle control. $300-400 for the sensor from there
3. Low compression in #2 and #4 (60 psi in #2 and 90 psi in #4)
4. Oil was 2 quarts low (they topped it off at the dealership)
They suspect that oil is going through the turbo, therefore the turbo may be going out. (quite positive that is the issue) If that is the case, between the low compression and the oil issues, a short block and turbo charger may be needed. After tearing down and installing the parts, the rough estimate is $7000 to fix. Also, they would need to look at the cylinder heads to see if they are bad, they run $500-$1000 each.
5. Mat is going to check with the mechanic to see if I should even drive it home. I told them that I don't want them to tear into it right now. I just want to take it home and do some research.
