Check compression, if good and even then suspect injectors. Good luck!

I had new injectors put in about three years ago ( 5000 miles ago ) I thought that was the problem, but it was not. Have not checked compression yet

I have checked pressure and it holds at 43 at idle. Have not checked at WOT. Injectors are boush 3. 22

At idle, with the hose off, it simulates WOT where you have no vacuum in the manifold. Bosch 3 24pph is ok. Where did you get them? Did they sit with fuel for the last 3 years?

Will check WOT. Injectors are 22. They were put in by corvette shop. I try to drive car at least once a week. Car has not set very long without driving or starting It had rough idle before replacing injectors. It had original injectors so I thought that might be problem. I'm leaning toward leaky EGR because of carbon build up in manifold or leaky valve
