Code 32 & 33, HELP!
Ok...this is what's happening. When I start the car, it idles low and erratically (even a cold start) like it's about to stall. Then after about four seconds, the service engine light comes on and the idle is smoothed out, but a little higher than normal. Then the car drives fine, but with the SES Light on.
I pulled the code, and it flashed 32 and 33. Can I get any help on what those are and possible fixes? Thanks in advance.

The 32 code could be a fault in your barometric pressure sensor, exhaust gas recirculation valve diagnostic switch, or electronic vacuum regulator valve
The 33 code represents a high voltage level at your maf or map sensor, or low vacuum at your maf or map sensor.

Are you burning your own eprom by any chance? I was getting Code 32 today. Looks like it is TunerCat V 1.61 that is causing it. Went back to version 1.60, re-did the changes to the eprom, worked like a hot damn.

do you have a gague to check the vacumm? if you can check that and it turns out to be the problem, most of the time you can just snip the hose a little if the leak is close to an end and put it right back on 
the vacuum should be around 18psi i think.. not to sure though...
as far as the map/maf goes, i always use a computer form snap on tools to display the readings form that sensor and just check to see if it is where it should be.. You can do this with a volt meter, but I don't know what the voltages should be right off..
those 2 things above would probably be the most likely cause of the 2 codes.
