Rough idle!

[pbsupra90]

I have a question.... when I am in neutral and the car is idling, the engine will kinda kick once in a while. It is a 1990 Supra Turbo. It seems to do it more when engine is warm. Just wondering what possible things it could be? Thanks

Could be a vaccum leak! Also when it kicks how much does the motor move I am just wandering because if it is alot you may want to look at your engine mounts to make sure they are still good. Just a thought but alot of the older Supra owners on here will be able to give you a little more insight on this. I am just pointing out the obvious to get you a good starting point til they can get to you. Also does the idling change any or does it move around.

What rpm is the engine at when it kicks? I'm guessing it is almost stalling when that happens.
