Hello all, new member but owned this car for 2 year about now and have been having been issues on and off. Recently did a scan and have multiple codes. Would like some help on how to go about resolving these issues as I have no idea anymore. Have moved the coils around and still misfiring on Cylinder 1. Would like any help with these and how to go about them. Thank you very much

Which engine,1.4, 2.0, or 2.4?
How many miles?
Which trans?

Check your oil level. Many2.4 engines use oil and that causes problems when the MultiAir has no oil. There is a Customer Service Satisfaction Campaign from FCA and you should have got a letter. It's like a recall, no charge.

28 - DTC-Based Diagnostics / MODULE, Powertrain Control (PCM), 2.4L / Diagnosis and Testing

P1061-CYLINDER 1 OIL SUPPLY SOLENOID VALVE STUCK

Theory of Operation

Multi-Air is an electronically controlled variable intake valve phase and lift system. Unlike conventional intake valve phase and lift system which controls all the cylinder intake valves simultaneously and in the same proportion; Multi-Air, through the use of an electronically controlled “ hydraulic link” between the camshaft and intake valve, allowing for each intake valve to be controlled independently. The valve lift and timing can be adjusted infinitely.

The Multi-Air valve train has a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The VVA Solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event the VVA Solenoid is commanded to either hold oil pressure or bleed oil. The Variable Valve Actuator (VVA) Solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA Solenoid determines the intake valve timing and lift. This change on valve action is similar to creating a change in the camshaft lobe profile affecting lift and duration of the valve opening.

When Monitored and Set Conditions

When Monitored: This diagnostic runs continuously when the following conditions are met:

•With the engine running.
•With no Battery voltage or ASD Relay faults active.


Set Conditions:

•The Powertrain Control Module (PCM) monitors the feedback current and determines that the VVA Solenoid is stuck.

Default Actions:

•The MIL light will illuminate.

Possible Causes

ENGINE OILING SYSTEM ISSUE
VVA SOLENOID

When Monitored and Set Conditions

When Monitored: This diagnostic runs when the following condition is met:

•With the engine running.


Set Conditions:

•The Powertrain Control Module (PCM) measures the time needed to turn on the VVA Solenoid. When the PCM recognizes that the VVA Solenoids switch on time is too fast or too slow a fault is set.

Default Actions:

•The MIL light will illuminate.

Possible Causes

ENGINE OIL LEVEL LOW
ENGINE OIL AERATED OR CONTAMINATED
INCORRECT ENGINE OIL FILTER
INSUFFICIENT OIL PRESSURE DUE TO A MECHANICAL FAILURE IN THE OILING SYSTEM
VVA ACTUATOR ASSEMBLY


The misfire and catalyst codes are probably from the MultiAir problem.

Any idea what that may cost? Thank you

If your oil is low, how much for a quart of oil in your area? The PCM flash at a dealer should be free. If the MultiAir brick has a failed solenoid, then you need to replace the whole assembly. That could be quite costly.
