I have a 2003 Silverado with the 4.8 engine with 63,000 miles. Since I purchased truck in March 2010, I have been getting a 'Reduced Engine Power" message and have to pull over and restart. I pulled code last night and got a P1518 (intake manifold runner control valve fault stuck open) any suggestions?
have the same problem?
