They are Autolite Iridium Extreme Perfomance XP 104 I bought at NAPA Auto Parts here in The Seattle, WA area from the guys and gal we have worked with there for over 12 years. Thats what they have listed as stock when I was at Ford and NAPA. As you all know, this sweet ride costs you to maintain.
I did go back and check and double check every thing I could as I took it back apart, and yes Every wire was grounded and checked to make sure the circuit was complete. The only slightly loose thing I found was a clip underneath where the wires run across to the alternator but more on the passenger side next to the intake and one of the cover's nut and washer post. Haven't had the time to look it up yet.
Its seems like it may be one of three overall issues revolving around fuel as per say trouble shooting via MK8 manuel... Cold plugs...some sort of issue having to do with fuel and or air mix and combustion....and then any number of things that have some kind of effect on any of the above.
Question about the throttle body butterfly valve, does it run in some kind of linear function or are the both supposed to open the same distance at the same time. With mine the driver side opens far and smoothly with some effort. The passenger side only opens as far as a reguler rulers thickness but does so easily. Is that normal function?
So far mass airflow sensor, injectors, TPS, airfilter, fuel filter, oil and filter, plug and plug wires, radiator and hoses, alternator and battery have all been replaced and the MAS and injectors were cleaned professionaly and I only use Chevron 92 gas. This was all the past 6 months or less and multiple times for the basics of course.
I know I hi jacked my own thread ha ha, but I have to systematicly go through and figure out whats working right and whats not. Just saying thanks to everyone for the opinions and input no matter if people agreed or disagreed.
