First I do not appreaciate the demeaning tone of your reply.. You assumed that I had not done or had done any work to the car.. My local tech did chk fuel pressure delivery checked thfuel for rust(found none) replaced the fuel filter.. checked the timing best he could..(I live in Bartlesville, OK 10 mi south of Kansas) so technical expertise is hard to come by.. replaced plugs wires cap and rotor.. checked the fuel pressure regulator was good.. states that the coolant temp sensor "seems" to be good as he is getting voltage to the cold start valve.. the idle was pretty bad but cleaned the idle control valve and it improved.. tech states all voltages appear to be correct.. the reason I asked the open ended question is that I wanted as much feed back as possible even if the feedback suggested things I/the tech had already tried.. the thing is it will eventually start and run great for a short while but go into limp mode shortly there after..usually after the time it takes to warm up.. so Im thinking o2 sensor or any other sensor.. the engine gets spark and fuel just intermittantly so suspect what ever is cause this intermittant running problem is why it wont start as well..you see I have done tons of trouble shooting for approx 5 month countless hours from me and 3 garages.. here in town...
