1999 Rodeo Rough Idle ?

[tdg038]

I have seen all the comments on rough idle and the possible cause is the intake gasket, my question is which gasket? The bottom gasket between the block and the intake or the upper gasket between the 2 manifold pieces or all?

Thanks for any help.

It's the lower gasket(s) between the cylinder heads and the lower intake runners. One gasket per side. The upper common chamber gaskets are much less problematic.

Thanks, already changed them out. It was a little harder than in the FAQ. The drivers side gasket was broken in the middle, never seen a gasket like that with the plastic spacer in the middle of 2 thin metal gaskets. Finally got the gaskets in and it runs like a top.

Thanks,
