Question about 2001 Subaru Legacy

1 Answer

I have a 2001 Subaru Legacy. It has been chugging at highway speeds and frome dead stops. I've changed the plugs and the motor seems to run fine except for a slight hesitation at idle. Once the car is revved up it smooths out and a few minutes later it will start again. It threw some codes such as the downstream O2 sensor and the knock sensor and the thermostat as well. I changed the thermostat and no are showing right now. The car still chugs though. Any Ideas?

Check the fuel filters and fuel pump, could be 1 or both dirty, need to replace if so.

Engine chugging


Spark plugs, air filter, or possibly water in your fuel. When your tank is almost empty, pour in a can of Sea Foam, then fill the tank with fuel. Sea Foam will remove water and clean your fuel injection system. It can be purchased at most auto parts stores.

How do you replace the spark plug wires on 1997 Subaru outback/legacy?


Access from top is better but you must remove battery/washer reservoir driver's side and intake piping on passenger's side to get to the plugs. If you have bad back, access from underneath is fine but I'd have a ramp instead of jack for safety reasons.

If your vehicle has a MAF (mass airflow sensor), try disconnecting it and running the vehicle. If it runs ok ... suspect the MAF.

Commonly, a fault with the MAF does not cause an engine check light

possible but sounds like you have a misfire occurring is your check engine light on if so this will give you a code determining which cylinder it is occurring on.i would start out with new plugs and wires especially if you know they have not been done lately

My 1992 Subaru Legacy Wagon is missing, I have changged the plugs and wires. It runs fine on the highway but has a problem in town where there are plenty of starts and stops. What else could be the...


You could try checking the EGR valve to see if it is dirty. It may be running badly at high speed also as it's harder to hear misses at high rpms. You should be able to tell by your acceleration and gas mileage also. Timing chain problems sometimes show up like this. Sorry I can't give you anything definitive but hopefully this will help a little. Good luck!
