With a diagnostic test we were able to find that the error code related to the “Bank 1 intake manifold flap stuck shut”. This intake manifold flap is a moving flap within the intake manifold which moves to improve the mix of air and fuel at different engine speeds, which results in an improvement in driveability, power and torque vs. without. With this stuck in one position the power, torque and driveability of the engine become limited and results in a check engine light.
So that we could verify the improvement in power and torque we dyno’d the vehicle on our in-house Mustang MD-500 AWD dyno before fixing the hardware fault.
With the Gallardo in our workshop, we were able to begin removing the intake manifold to reveal the intake manifold flaps…
This then revealed that the Bank 1 actuator arm had failed. A simple fix, with a new, Genuine Lamborghini part ordered and delivered to us overnight we were able to replace the faulty item and test the repair.
With the faulty part replaced, check engine light cleared we headed to the dyno to verify that this part was causing issues. This Gallardo gained a huge 20hp and 14lbfts throughout the rev range and is now running fault-free with no check engine lights.
