I have had similar problems. The P0302,4,6, and 8 could be the ignition coils, but may be a faulty alternator. I had replaced one ignition coil, but only found out that the alternator was bad. I still have check engine and VSC light on. When I put the key in the ignition and the panel comes on, I can turn the VSC on and off, so the switch is OK. I know I am adding info--hopes it helps someone. Good luck

Why is my car misfiring in cylinders #1,2,4,6 please help!
Where did you get these codes? Anyone can by a scan tool, but if they cannot tell you what the mean is a a joke and do not waste your time . All codes are OBD ll and are available on line free try googling P0301
You have 23 year old car and you will have to decide if the repairs are worth it.

Exhaust camshaft on bank 2 is out of time. It could be the camshart control valve or possibly the the camshaft has slipped a tooth. Focus on the P1354. The other codes are secondary to this fault.

Timing belt is a bit stretched. Time to have it replaced. Toyota has to be dead on the money, when it comes to the timing marks. I done several of them and you have to add extra pressure to the belt tensioner to make them run right.
