Interested in any input.

Car starts and runs fine. After car reaches operating temp, runs irratically in midrange. Have new plugs, new rotor cap, new distributor cap, new plug wires. Injectors, fuel filter and fuel pump pressure check out ok.

 

is the idle air control valve going?

check for vacuum leak, one of my car did something similar when it had a leak on the intake manifold gasket behind the head.

 

Thanks for the input.
