Just replaced the intake gaskets to try and fix a warm/hot idle p0171 problem that otherwise matched all the cold idle problems. Yes, that was it! Also - no more weird pulsing sound. I figure one of them was leaking, causing that - and that seems to have been true. Tip when assembling - use high-tack gasket spray to hold them in place while you line up the manifold with the ports. Bryan
