My 2002 subaru outback
has 55,000 miles and several days a week starts spitting and sputtering for no apparent reason have tried different grades of gas and also have added dry gas. and at times will stall out. at one point check engine light came on. and scanner read code P-172 which means cylinder failure. Can you help?
Looks like you need a good tune up its a little early for this engine but i have seen alot of bad plug wires this year. so at least plugs and wires.
i think this should cure your problem

I have 2002 Subaru Legacy L, that keeps sputtering when light pressure is maintained on the accelerator pedal.
I have 160,000 miles on it and just had the head gasket replaced. The sputtering only started after having this job done. Most noticeable when maintaining light pressure on the accelerator pedal. The car just suddenly starts sputtering.
The dealer cannot find the problem, as the check engine light does not come on. They have hooked it up to the computer and get no error code readings.
Any ideas?
Thanks
