    i'm having the comparable subject. I replaced the wires, coil, distributor, idle air administration valve, map sensor, oxygen sensor and throttle place sensor and my truck nevertheless idles incredibly intense. once I depart the vehicle engaged on idle for an prolonged time the verify engine gentle comes on. At that factor you will desire to be waiting to get a code from the two an OBD a million or OBD 2 gadget relying on the 300 and sixty 5 days of your vehicle. i will purchase a diagnostic gadget and plug it in whilst the verify engine gentle comes on. i do no longer think of you have become a code because of the fact the verify engine gentle isn't even on. i think of it must be on for it to output a code. additionally verify for vacuum leaks. replaced the PCV valve and all the vacuum traces that are cracked or appear like there is an air leak. additionally, in the experience that your vehicle is doing a ruff idle and it sounds like it is going to tutor off, it might desire to be the EGR valve it incredibly is caught open. If the EGR valve we could too plenty exhaust lower back into the intake manifold your vehicle will studder and would turn off. replace the EGR valve if it is so.
