Engine Performance problem
1999 Toyota 4Runner 6 cyl Two Wheel Drive Automatic 139000 miles
When I start my 4runner in the morning or when the engine is cold, it runs perfectly and will continue to do so for as long as it is running. But if I stop and turn it off, it missfires in the #1 cyclinder. This is ony afetr it is warm. After about 5-10 mins of driving it will eventualy smooth out until I stop again. The check engine is on and the code is P0171.
Just a recap:
Runs fine when cold and will continue for as long as I drive it
Misses when turned turned off and sit for about 15mins and turn back on, and it really runs kike crap.
Will smooth out after about 5-10 mins of dirving until I turn it off again.
Does this sound like an MAS?
have the same problem?
