I have a 2001 LX470 that blew the t fittings and had to replace them. I decided to change valve cover gaskets and upper intake manifold as well as spark plugs and PS pump. Since the fluid leaked everywhere I got it back together and I'm getting a crap load of codes. 2 P3000 random misfires as every misfire cylinder but #4. I started it and it ran fine then bogged down and flashed the blinking check engine light. It Revs just fine but throwing codes and hissing like a vacuum is not connected but I checked all of them. Looked at the plugs and they are dry. May be dumb to something but can anyone help on this? Am I looking at electrical short on all coils?

P.S. started smoking when started up first time but looked like from the exhaust with with fluid that went everywhere. And the ASC and the other light came on also.

Ok so found the leak on the upper intake manifold by spray throttle body cleaner around the areas and seeing where it would choke. More to come hopefully that fixes all!
