Car knock at startup
I have a 1999 Plymouth neon 2.0 SOHC, 130k miles
The car runs great for what it is:, but once its warmed up and i shut it off and start it right back up i hear a loud knock/bang just for a second, it sounds like an overheated knock start up if you know what i mean, but its Not overheating at all, in fact i have replaced everything on this car as in radiator all houses timing belt water pump all pulley's harmonic balancer motor mounts.
if i shut it off and let it sit for just 10 minutes then start it up i don't get any startup knock, so why does it knock only when i start it right back up?.
Thanks for anyone who can help, This problem is driving my nuts for a few years now..
