Whats up. i have not been on here in a long while.. I am goin to thanx Rod first in advance.. So in my last post i talked about having issues with my v6 ls.. to start with its still lean in bank one and two.. cyc 3 & 6 are still misfire.. So here is what i have done with it. I have changed all the coils, plugs and fuel rail. Changed all 4 O2's also have changed the pvc valve and hose.. changed both cadillac converters & both exhaust. could there be a relay thats blowin still at a loss

After you changed the coils and plugs did the misfire go away for a short time, or did it always remain? Did you find any signs of water or oil on any of the coils? Did the spark plugs in cylinders 3 and 6 look any different from the others? Have you checked compression on those two cylinders?

i noticed that it smelled like gas on 3 & 6 but that was bc it was runnin lean when i changed the 02s and the coils it ran awesome for about 2 weeks and i loved it but one morning i started it up and its like its crap and started doing it once more i have yet to run a compression on those two cylinders yet.. that was my next step but im kinda tight on cash right now bc i keep putting time and money in on this issue

If it ran fine for 2 weeks after changing the plugs and coils then compression is not likely the issue. It's probably either something getting in the plug wells and shorting the coils, something getting in the cylinders and fouling the plugs, or something with the wiring to those two cylinders.

A lean condition would not cause the plugs to smell like fuel. If the plugs were failing to burn the fuel, that unburned fuel would be going in to the exhaust and cause a rich condition.

If you're taking the car to a shop to have all the diagnostics and "repair" work performed, it seems like you need to find a shop with true technicians that can troubleshoot the issue, not mechanics that throw parts at it. If you're doing the work yourself, then it sounds like you could have saved some money by taking it to a shop with the proper equipment and proper understanding of the equipment to diagnose the problem.
