Blown head gasket first, replaced head, and associated topend gaskets, including exaust, lower intake and upper plenum gasket, new plugs/wires, timing belt and water pump. Hard to start initially, runs but no power, checked for vacuum leaks found none. Drives like it is in limp mode, went to auto zone to see if there are any codes stored. There was no power at diagnostic port, verified fuses, relay and diode, all good. Checked voltage at IAC, 4 V. With engine running can disconnect maf and/or IAC, and engine still runs, any ideas?
have the same problem?
