Codes 22/33/34

Well I have repaced the TPS and adjusted it properly w/ a digital VOM, I have installed a brand new Bosch MAF and new burn-off and power relays as well. Reset the computer and I'm still getting these codes. Am I missing something can anyone help. Sometimes the car runs awesome, sometimes its not much faster than stock 305. I should also point out that the SES light is intermittent. When i'm cruising at a steady speed it goes off, however when i brake or decelerate it comes back on. Any input or help would be appreciated. Below are specs on the car:

88 Formula 350
ported stock heads comp cams xr269
heddman shorties
deleted cat
3" cat back
crank ud pulley
tb airfoil
custom CAI
toque converter switch

Your code 22 is for TPS voltage low. The voltage should be .54 volts + or - .08 volts. I don't really think that you would be getting a code 33 & 34 at the same time. One is for MAF sensor circuit (GM/SEC HIGH) & the other is for MAF sensor circuit (GM/SEC LOW). Since the SES light is intermittent, it could be something else or nothing at all.
