Runs bad, need help asap, see codes.
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.

also it was consuming oil so i put 1/2 a bottle of seafoam in it. that happend 2 weeks ago.
not sure if that can play a role in this but I wanted to mention it.

Yes, the seafoam can cause the car to misfire. But, 2 weeks later, unlikely.
How many miles are on the RX? Have the spark plugs been changed? Which code came back first?

also i checked a ton of threads and nobody list a solution, they disappear like a fart in the wind.
I promise to post the resolution when this is done, i just need advice on what to do.

it was getting crappy millage and consuming oil, i looked for sludge and found nothing so i figured something was gunked up and hoped sea-foam would clean that out.
i drained and changed the oil, but i still have a non running car. i went the change the downstream o2 sensor and the previous owner broke the studs and cobbled a new one on. I am thinking about taking it to a shop now.

ok, i changed the oil, replaced the downstream o2 sensor and it still ran rough, i again checked the codes and P0304 was present, so i changed the coil for #4 and it runs great, but... when i start it up after its been sitting, it smokes for about 3 minutes.
