Hi Scotty!
I have a 2001 Toyota Camry v6 with 117,800 miles miles. Today I changed the ignition coils, spark plugs(xp iridium by autolite), wires(NGK), both valve cover gaskets, and pcv valve. All new. It was a mess. lol Upon start up the check engine light came on solid then flashing. I currently have error codes P0300, P1135, P0301, P0303, and P0305. Everything looks to back in its proper order but now Im stumped. What do you suggest?

well, you messed something up. realize the back ones really require removal of the intake to do it correctly

Yeah I removed the intake to get back there. Spark plugs maybe?
