Message Ok guys...I am about at the end of my rope here. I think I might know where to turn next, but before I take one more thing back apart AGAIN or spend another $ on something that doesn't fix this; I wanted to at least get some follow-up 2nd & 3rd opinions>

Primary Problem (now) - No fuel getting to Drivers side bank. I've got good spark, lifters are new and clicking away; but if I pull the coil (any driver side plug) NOTHING! No change whatsoever! The only change I found is if (while one non-working coil is removed), I remove one of the passenger side (working, which severely retards the engine) and then put the "non-working" coil back on; there is a very sight improvement (but nothing like plugging the working side back in). If I leave the coil off; while the car is running, and pull the plug, it is -Bone Dry.

SO..I know fuel is getting to my drivers side, but doesn't seem to be getting to my Driver's side? I know my next test is going to require me to get a compression tester and test each cylinder and maybe that may be my answer in wait; but do yall have any other ideas to throw out as to what this might be?

The only thing I can think of, is that when I changed my TB (about a year ago!), I possibly got the Driver's side cam off a notch?? Unsure as when the original hesitation/bad idle started; I tracked down one bad injector that I thought was cause of the issue. That and every other fix I completed over the last year (All new injectors,new connectors, new EGR, new PCV...all seemed to make the car run better and smoother, to where the car is finally idling perfectly!

The only issue_A perfect idle on 3 cylinders that hella-hesitates on take offs, but seems to run as my rpms increase and I clear the excess fuel out of the chambers.

Comments??? PLEASE!!! Is there a good possibility that I somehow got the cam off a notch and that is causing my right side to fail? My only issue is that I swear somewhere along the way (while working my injectors) I did a run balance test on the drivers side it was working previous!

Would ANYTHING else make a whole side of cylinders fail even though spark and "click" is there?

Thanks!
