Stalling at stop signs after replacing battery
2005 Outback 4-cyl non-turbo with automatic trans has been stalling at certain stop signs. Drove fine for 168,000 miles.
But six weeks ago after I had the battery replaced, idle speed dropped to near zero. Then 5 miles later I gassed up, at which point the check-engine light came on. Drove 20 easy miles, but the fabled relearning did not take place.
Next day, mechanic fixed the idle problem and reset the check-engine light, but said the code indicated possible need to replace the throttle actuator, a $600 part. Instead he cleaned that part. And had me come back another day when he thoroughly cleaned entire throttle assembly, hoping we'd not need that expensive part.
The intermittent stalling at stop signs continues to get worse (usually on a slight uphill), but no check-engine light except for one day last week, which prompted me to go to a dealer asking for computer reset.
By then check-engine was no longer on. Dealer verified the stalling problem, said trans fluid was jet black, did trans flush and trans re-learn, said problem "probably" solved. Also said no active codes, but one "inactive code" indicating catalytic converter.
Stalled for me at stop light 200 yards later, and continues today intermittently but gradually more frequently. No further check-engine lights. And still fails to stall when regular mechanic test drives it, or when a transmission guy test drove it on Friday. He said he found no codes. And he said since it seems to be worse early in the day it might not be a transmission problem.
If I come to a stop very gently, sometimes that prevents it stalling.
If I pump the gas when it's starting to stall, sometimes I can prevent it stalling. Risky at a stop sign of course.
If I slip it into neutral when it's starting to stall, that prevents the stall but only until I slip it back into drive.
Every time it stalls, I retart the engine easily, and at that point
Driving me crazy.
