Just recently tackled a head gasket job, had the head machined shoped and needed exhaust vavles.i put a new chain, tensioner , along with guide kit.TDC, camshaft and crankshaft marks perfectly to the timing marks on the chain. new plugs, new ignition control module , tested coil all are perfect. i checked and tested for vaccum leaks, none. tested and replaced throttle position sensor. the engine run (as before it was dead) but it is rough on idle. when i give it gas it sounds good but pulsates. i need some help
