Miss between 2700-3200 rpm. Egr?

[Chad Long]

I've got an 87 with a miss that I can't diagnose. After warm up it has a intermittent miss between 2700 and 3200 rpm. I've replaced distributor cap, button, wires, plugs and fuel filter. Since it happens after warm up I'm wondering if it could be the EGR valve or O2 sensor. Anyone else ran into this?

Have you checked for stored codes?

Yes, couldn't make sense of it. 6 then 11

Take a look at your spark plugs too. They can give you a good idea of what's going on in your engine.

Already pulled them. They looked good.

Maybe this thread will help

Thread: Check Engine light. Codes 4 and 11.

Code 11 is typically a bad Throttle Position Sensor. Have you checked to see if the egr is fully closed when the engine is off?

It could also be fuel related.

Yes, attached a hose to it and applied vacuum at idle. It stumbled so I thinking EGR is probably fine. I've got injectors on the way. Figured it can't hurt to have new ones.
