This 2001 legacy doesn't run very well, was running super well up until this past monday (jan 20). I've spent the last 2 days trying to fix it as I really enjoy this car. It runs well for approximately 1 minute then begins to idle poorly and then there is no longer any throttle response. the issue could be simple or it could be really bad. so it could be worth fixing up or just to be used as a parts car. The original owner kept a very detailed history of all the maintenance and repairs done to the car which is still in the car, there are 4 good used tires on it now, toyos and 4 winters in the trunk. I installed a brand new front rack and pinion in sept of 2019. Front pads, rotors and calipers all fresh from this past october. new A/C and alternator belts in december, when i purchased it there was no stereo so I've removed my sony deck and speakers. It is a standard 5 speed trans and 2.5L engine. Great AWD vehicle if it can be repaired. replaced the spark plugs, tested the spark plug wires for resistance, cleaned O2 sensors. Check engine light is on, without a diagnostics tool I can't figure out what exactly the issue is. Timing belt, clutch and head gasket replaced at 165000kms
