The initial engine code was 0304. I R and R'ed that plug but the problem persisted. Since the symptoms appaered fuel system related I have done a number of things diagnosticly and replaced parts.
-new fuel filter: no change
-new fuel pump: no change
There is no smell of gas. The fuel pressure regulator is behaving normally. Fuel system pressure is within tolerences. No codes are shown when the reader is attached when driving. The car starts fine and idles smoothly and at the correct RPM even after warm up.
have the same problem?
