I have a 2001 Dodge Dakota with the 3.9L V-6. When the truck is first
started, cold or after sitting for an hour, it hesitates, boggs,
misses, etc. but there is no MIL (check engine) light. I have changed
the Plugs (champion), wires, cap and rotor (all mopar) and it still
misses. I took it to a dealer and they told me that there were codes
for numerous misfires especially #1 cylinder. They also said the
adaptive memory had adjusted the fuel to full rich. They cleared the
codes and memory allowing the fuel to readjust to the starting point.
This didn't help, the truck started missing when I was leaving the
dealer. I then tried filling up with super premium and a bottle of
Fuel injector cleaner. I though that fixed it as I had no missess for
a couple of days but then it came back. Any suggestions would be
appreciated. The dealer says their next step would be a comression
check which I'll probably do myself this week.

Thanks,
