i have a 98 caravan 3.0 that has p0205 p0305 codes i know the two are related i have replaced the number 5 injector and there is no signs of the harness being melted or messed up in any way but im still having the same codes and the same problems with the van ie. hessitation at take off/ low rpms it runs fine when its cold but when it warms up is when its problematic here is a list of what i have replaced on it in the last couple weeks granted some of these have nothing to.do with the problem plugs, wires, cap, rotor, pvc, fuel pump, fuel filter, number 5 injector anyone with any suggestions please help..

 

Symptom:
P-0205 INJECTOR #5 CONTROL CIRCUIT
When Monitored and Set Condition:
P-0205 INJECTOR #5 CONTROL CIRCUIT
When Monitored: With battery voltage greater than 12 volts, the auto shutdown relay
energized, injector pulse width less than 10ms, and engine speed less than 3000 rpm.
Set Condition: This trouble code takes .64 to 10.0 seconds to set when no inductive kick
is sensed .18ms after injector turn off, and with no other injectors on.
