I have 85k miles. During cold starting there is a stumble for a second until the engine reaches cold idle RPM. I put in a set of new plugs, old ones didn’t look bad. Engine runs smooth at idle and all other RPM’s. Anyone have a similar problem, bad coil or injector?

I am having the same problem. I thought it may have something to do with my cold intake or free flow exhaust. I'd appreciate any insight too.

Thanks,
