This is a weird one. Car is fine when cold. When it gets warm it misses at idle only in park or neutral. When I put it in drive or reverse it idles smooth.

I replaced all the fuel lines and o-rings. The car has excellent power and pulls without missing when flooring it.

I am thinking one or both of the fluid motor mounts went bad and is not keeping the idle steady. When I put it in drive, is the fluid in the torque converter dampening the motor?

I also cracked the fuel lines at each injector. Each one actually made it idle a bit steadier. So I did not see a particular problem with any one cylinder.

Any ideas or agreements with the motor mount theory? There is no vibration as if the mounts are bad. Just the missing shake.
