Had tune-up done. Plugs, wires, oxgen sensor, fuel filter, etc. At cold idle engine misses but not badly. Starts good but can hear an intermittent poom-poom sound through the exhaust. It gets better after it's warmed up. My mechanic replaced a plug and cleaned the egr valve. The miss is still there. The miss is much more pronounced when I hit the gas hard pulling up a hill especially when it's cold. He says I need to replace the egr. I think it's a bad or partially clogged injector or maybe the idle air control valve. Your thoughts?
