On my 2005 dodge grand caravan 3.3L engine when with normal gas pedal pressure the van runs & shifts fine but if I put to much pressure on gas pedal it starts to blog surge or whatever. Check engine light is also on a scanner shows a p0016 crankshaft code could this be the problem.

You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?

I have the same problem. My Lincoln Ls wrench light comes on and it quits. All spark plugs, all coils and the throttle body has been replaced. I think the LS model is a lemon! Any information or suggestions will be appreciated.
Thanks, Betty
