Key is that a secondary ignition problem like that will often only set a P030x (misfire) code while I would expect a fuel pump/regulator/injector to report an over lean condition (P017x).
ps electrical problems often surface with age and not mileage.
I appreciate the specificity of your reply. I've been meaning to get a code scanning tool, and this seems like a good enough reason to buy one. I'll see if I can come up with the codes the computer might be retaining and then take the car back to the repair shop. I could always take it to a Chrysler dealer, but that would a last resort. Except when under warranty, I've not had good experiences taking cars to dealers.
