replaced the injectors to 19lb bosch 3 , new fuel press regulator, tpi gaskets , cold temp switch under the intake , new iac valve ,deleted the egr , no cat ,installed hooker shorty headers , removed air pump, car has new plugs /wires . coil cap and rotor
it runs good after warmed up but extremely rich and will not idle until warm

Re: horrible idle
Did you check the coolant temp sensor at the front of the intake manifold?
