Engine knocks at idle. As soon as I hit the gas it's gone, but resumes as soon as the rpms go down to under 1000. It's an intermittent knocking, not pinging. It quiets down but is still present when the car warms up. Car is a fully stock 5-speed 89 with 135800 on it. Spark plug wires are all seated firmly at both ends. I dunked around with my exhaust manifolds once a while ago, but I was able, to my knowledge, to get them back on tight (those things are so hard to work with!).
I'm sorta stumped cuz of the when-where-how it knocks.
