Well, I'm snookered. I'm still getting this P2013 code.
The car seems fine when cold and for about 20 minutes or so, then I start to get hesitation when cruising, then the MCSF light and limp home.
Code will still be there next day, although again it will run fine for a while.
is a good site for giving info on what the codes mean, as for P2013
Number = P2013
Type Powertrain = Fuel and Air Metering and Auxiliary Emission Controls - ISO/SAE Controlled
Description = Intake Manifold Runner Control Circuit High
Location = Bank 2
Notes = DTC Application note for Intake Manifold Tuning Valves and Intake Manifold Runner controls: Active controls are used to modify or control airflow within the engine air intake system. These controls may be used to enhance or modify in-cylinder airflow motion (charge motion), modify the airflow dynamics (manifold tuning) within the intake manifold or both. Devices that control charge motion are commonly called Intake Manifold Runner Control, Swirl Control Valve, and Charge Motion Control Valve. The ISO/SAE recommended term for any device that controls charge motion is Intake Manifold Runner Control (IMRC). Devices that control manifold dynamics or manifold tuning are commonly called Intake Manifold Tuning Valve, Long/Short Runner Control and Intake Manifold Communication Control. The SAE recommended term for any device that controls manifold tuning is Intake Manifold Tuning (IMT) Valve.
I've checked the EGR, cleaned and greased the solenoid and checked it moves freely using FiatECUScan, cleaned the MAP sensor, can't do much with the MAF as it's a sealed unit.
I'm loathed to give it to a dealer as they'll just use the scatter-gun approach, change bits willy-nilly and charge for the bits that didn't need changing.... heck, I can do that.
Could anyone suggest where I might look.
All the best
