I am inquiring on my 2011 P7B 250k Car always runs amazing and fast and no issues. Shifts excellent. I just had a shop replace the intake manifold, it was leaking/losing coolant etc. Believe it was the original.
Upon getting it back, there is an ridiculous loss of power and acceleration, noisy and stalled once. I thought I was driving a different automobile. That is not this car. The shop checked vacuum, wires etc. and was all good. They did say they would make good on it and would possibly need to order a dealer one instead of the Napa one they repaired it with. You could imagine my disappointment. Any thoughts or similar experiences?? Thank you*
