Hard starting v8 -easy fix
For about a year now I've had a problem (usually with warm starts), where I've
had to nurse the gas pedal to keep the motor from stalling after start-up. At
least once a day, but not too bad. I just learned to live with it. The
engine speed sensor was most likely the problem, I was told.
Just over a week ago I was checking my coolant leak, which turned out to be
the upper radator hose, and consequently brushed up against the ISV connector
and noticed a slight increase in rpm. Hmmm...removed connector and engine
died. Left off connector and engine would start but not idle as smoothly as
when I had temporarily bumped up against the ISV. So I cleaned the connector
pins and reattached the connector.
Over one week without a hard start/stall problem! Guess the v8 was running
pretty good without the ISV operating, or operating intermittantly. It seems
my fuel mileage has been somewhat better also.
