Yes thanks. MAF , and both relays replaced. I'm leaning towards a vacuum leak throwing off the readings on the MAF or a bad connection . Maybe an intake leak or hose? I found one at the small PVC hose that goes to the intake by a youtube video. It evened out the surge but did not fix the CEL.

I found the culprit , EGR vacuum connection. It was broke where the plastic hose feeds into the rubber sucking air.The other leak was at the manifold where the short rubber hose connects the pvc pipe but I fixed that already. So far I can't get the CEL to come back on after several attempts.

That makes no sense, at least to me. That is an air leak which is going to show up as a low IAC count. How does that translate to a weak spark?
Was the spark issue fixed and then moved on to MAF?
