2005 Chevy Silverado V8 Four Wheel Drive Automatic 40000 miles
I recently installed headers on my Silverado 5.3L. Around the same time, I also replaced my spark plugs and wires. I also installed a tuned chip. At first everything was great, I then started getting a fluttering noise after a couple of weeks. At first, I thought it was a gasket leak. I retorqued the header bolts to specs, and the collector bolts as well. I still have the noise. It only occurs when I'm accelerating, or the engine is under stress, going up a hill for example. Could this be a valve issue?
have the same problem?
