The odd thing is the vehicle makes no lifter noise at all when it's first started (Idles fine) after a few minutes. Then there will be an occasional ticking noise with rough idle , but actually sounds normal while driving it and at the light it will run poorly then straighten out upon acceleration. I sent the ECM in so I can't start it an record this noise but it sounds like a spring letting loose ( AFM lifter letting loose?). I have a Autel Maxisys so I can activate or de-activate these lifters, but there is no noticeable noise difference, but it does seem to make the engine run poorly. I'll know more when the ECM gets back. Received the tool / feed plugs today. That was quick. Fastest shipping I've seen here!!!!
