Have an 04 100 series with 2uzfe. Has 263k miles. Recently bought. Test drive went great. Driving home cel came on along with VCS OFF & VCS TRAC lights as well, first time code was cylinder 2 misfire. Read that is common when getting gas with one that has sat and with old gas cap. Bought new gas cap reset codes. Next day all lights came back and code came back as air box maf. Cleaned air box and sensor, reset codes. Next day all lights came back, codes come back as downstream bank 2 02 sensors. Replace both. Next day all come back, code comes back as p0430 with 3 tabs on something with the evap system. Now I don’t have the money at the moment to buy catalytic converters (even the cheap ones), nor the money for a new evap valve, question is, Would I be able to go to work (approx 32 miles each way, 34 minute trip each way) for a couple weeks and be okay till I would be able to afford professional diagnosis and treatment?

New to the Land Cruiser owners. Thank you all for the advice.
 
Yes except for one DTC (MAF sensor). MAF sensor is very sensitive. If malfunctions, can result in burning up CAT very fast. Replace it with new OEM from Toyota, is best.

If gas cap old, or after market. Replace it with OEM. This may clear up EVAP (undisclosed) DTC.

P0302 if fuel related, from being parked to long. Could be a clogged fuel injector. Running fuel cleaner, like 44K, may help.

Make sure spark plugs aren't walking out:

Make sure no vacuum leaks and good air filter.
Also engine coolant system running a peak
