Code 33 fixed
I have been having constant Code 33 error messages when driving at any speed rain or shine. Replaced MAF, IAC, both MAF relays, TPS, fuel pump relay, and traced all wiring. I would still get the SES light when I would give it a little gas. Found that the oil pressure gauge was showing 6psi with the engine off. Replaced the oil pressure switch (without pulling the distributor) and code has not shown up since. This may not be the fix for every code 33 but it sure fixed mine. Car runs perfectly now.
