Re: 1996 TACOMA HARD TO START WHEN WARM
I have the same issue, however I have a CEL on - error code is that the
front 02 sensor is N/g. Also when emissions tested; failed as "running
to lean". My guess is the too lean issue causes a vapor lock when it is
too hot (or something like that). Playing with the gas pedal will get
it started MUCH earlier than the wait time you describe.
Problem I have is the 02 sensor was already replaced last year,
supposedly, although I suspect the old one was just reconnected and
attached - my brother-in-law owned it then and just before I bought it
the same garage said "oh. maybe it was the rear one.
Now the code says (again) the front sensor is n/g per Autozone.
Downside is it will co$t to try my theory. Also I have an exhaust leak
AFTER the catalytic, but before the 2nd sensor.
Not sure what to believe, but it seems that if the front sensor was
working and the 2nd didnot seefull exhaust, then if anything it should
run richer as the 2nd sensor is seeing less exhaust. But then you get
into ppm etc. etc.
Dealar basically wants to just basically replace the entire car, which
is honestly not honest.
Digging through the Internet now....
