Just baught a 1993 SSEI, it runs great and has 123K on it. Has a idle problem though, when cold it will idle fine and sometimes drop down a few hundred rpm and start missing and the computer will then kick it up and it will idle fine. Does that when cold intermittently. Then when warm it will have a steady miss at idle when your stopped in gear and low rpm when driving. When you stomp on it it has tons of power and will not miss a beat.
Any ideas? it has new LIM gaskets, reman supercharger, new plugs and wires. Not sure where to start, vacuum is good and been unable to find which cylinder is missing.
