Volkswagen Repair: 04 Jetta with all kinda codes, sam s club, random series

Question
I have an 04 1.8T Jetta with 120K on it. Last night after leaving a Sam's Club the thing went nuts and wouldn't build any rpm. I had the engine light, the EPC(?), and another. Codes are P0237,0106,0343,0102,0606 and 2138,2637. I read that I may be able to "reset" the computer but??? Help I'm on a budget....

Answer
Robb,
 The readings are definitely all over the place, I don't see a lot of correlation.  So my first thought is (hopefully) a momentary electronic fluctuation that has "confused" the computer.  If you have access to a scanner, then go ahead and do a reset of all the errors.  Then take it for a test drive; it may take a while for the computer to settle out and the car to run better.  Do not disconnect the battery to reset it, it could cause other issues.   If things aren't better, do another scan.  Do the same codes come back?  Then it may be a hard fault.  Or are they another random series of errors? Then the computer may be bad or there is a more general electrical problem.
