Ok,Hope the links posted will help you out.Also,if this began after you installed a larger TB,that can be the problem sometimes too.
If the minimum air to TPS setting is off on the larger TB,or new engine with mods,etc,it will throw a code 33 and run poorly.This happened when I tried a larger TB once before and had to figure out why it kept doing that.Im not saying this is your problem,but if you cannot get it figured out,try putting ths stock TB back on and set the minimum air and TPS and see what happens then.
A code 33 is also an unrealistic flow of air into the engine that the computer is seeing due to incorrectly adjusted minimum air speed/TPS.
