Engine Performance problem
1999 Toyota Corolla 4 cyl Front Wheel Drive Automatic 71400 miles
CEL is on since April. DTC is P0441/P0446. I went to auto shop. VSV (vacuum switch valve) under front hood was changed. Charcoal canister was replaced in rear end underneath. New gas cap was put on. Smoking engine was used to test leak of fuel. Unfortunately, all thes seem not working with my car. The check engine light is always back again and again following a couple of miles driving after each repair. The DTC is P0446 now.
Any suggestion or advice? Thank you!
have the same problem?
