I have p0171, p1443,p0420, p0452 codes are poping up on CEL for about 3 years on and off, now the light has not gone away this year...
(started with p1443 only)
I have done so far:
a Cat Cleaner fuel additive
Cleaned with carb choke cleaner: EGR Valve and Purge Valve (soloniod test feels like they move)
I was thinking of buying the 3 O2 sensors first..
What should i start with? I just need a list to work with, any help would be GREAT!
Do i need to buy a particular exhaust since i now have moved to New York?
I would like to do the work myself, but volunteer full time and don't have 1K to purchase exhaust..., what is the possibility it some thing else?
Thank you in advance, ask any questions Please!
2004 Subaru Legacy GT Sedan MT , when i bought from the dealer the light came on a few days in and they replaced the EVAP canister (3 years ago). then it would just in the fall the light would go on and off on and off.
then it turned into winter it would stay on, but go off when it got warmer out.
now its just staying on.
every once in a while when filling up/ sitting idle, the car would not like to start or would drop below idle, ( i felt that if i rocked the gas in the car i could get it to start and then i would have to step on the gas to burn off a little of the gas before it wouldn't have an issue of stalling..
[not sure if this last point is in conjunction with the codes or not..]
