Chrysler EFI

[M. Jones]

Hello--

Anybody out there doing anything with Chrysler systems?  The 5.2L in my Durango 
is probably the worst 'modern' engine control scheme I've yet driven.  It's 
lifeless and unresponsive below 2800 rpms, when it suddenly wakes up.  (It's so 
sudden that I don't believe it's cam specs causing it.)  Response on initial 
tip-in is good, until about a quarter of a second later, when it then feels 
like a lean condition sets in.  It then kind of sags and surges in a minor, but 
very annoying, way throughout the acceleration regime.

A replacement O2 sensor did not correct the symptoms, and a friend with the 
same engine in his pickup reports the same behavior.

Any ideas?
