Gents,

Its been some time since I've made any progress on my build. During this time I've been starting the car, pulling it out of the garage and sometimes taking a spin around the neighborhood.

I got lazy and last started it in January. I did notice that that last few times it would backfire and run rough for the first few minutes.

I've tried, on two separate occasions, over the past few weeks to start it with no success. It fires and on a few tries has sputtered for several seconds, but that's it.

I've connect my HPTuner and re-flashed the stock LS6 tune, which it has been running, and ensured the vats and security is disabled.

I purchased two new coils in the case I find 1 or two bad coils. The plugs are iridium and the oil is Mobile1.

I wanted to get some input form the forum. Thanks in advance.
