ok so I went and replaced the direct injectors and the port injectors. Replaced the gasket on the intake manifold while i was at it and guess what.. still misfire on 5 and 7. What else is there to do? I'm getting really upset with myself cause I know its got to be something simple that I'm missing. There's got to be an electrical problem since everything is replaced. Something with the computers needing to be reset or something. Does anyone know and can anyone help? I'm very frustrated and not at anyone here but at lexus for not even stepping up and answering this cry for help. The dealers threw in the towel after taking $2600 of my money and didn't do a dam thing. Someone? Anyone?

Have you checked compression on cylinders 5 and 7?

I know what is happening and it is VERY bad. Sorry man. Couple of questions to zero in: what oil (weight and brand) are you using/used pre? any unusual noises from top end?
And laughed/cried so much - it's a timing code, not an injector code...

Boykie brought a valid point regarding cylinder heads in PM. Tnguyen528, have you had a recall done on your engine to address valve guide issues? I believe, in some cases dealerships ended up replacing cylinder heads.

I'm usig Mobile 1 0w-20 not using anything used. Have had no recall work done on the engine. Not to my knowledge. How or where can I check on this recall work and how do I fix this timing issue? Is it something I can do? Thanks for helping guys.

Honestly I was very iffy about asking people for help on a forum cause I thought no one knew what was going on but all of you guys have been way of a bigger help then any of the dealerships. I thank you guys and wish I can return the favor sometime soon. You guys are awesome.

Top end noises? Tappet? Ticking? etc
