99 Rx300 With 12 Codes, Runs Bad

[jevanof]

Hello I have a 99 RX300 and the check engine light was flashing on my way home from work, here are the codes that I am receiving.

P0300

P0301

P0302

P0303

P0304

P0305

P0171

P0136

I cleared the codes and all 12 came back

Any suggestions other than take it to a shop would be greatly appreciated.

you may have some bad coil packs...time to do some swapping and see if the codes change.
