GMC S15 EXHAUST PROBLEM

1994 GMC S15 • 280 miles

My 1994 GMC S-15 Jimmy will not idle properly when in Park. It surges from 700-1500. If I put it into gear it settes down significantly. I've changed wires, plugs cap/rotor, cleaned out the EGR and it's passage and put in a new IAC just to be sure. I also have a new exhaust from the manifods back. HELP.

Did you make sure there was no carbon holding open the egr?
