Code 33 on start up question

Had a strange thing happen today with my 87 iroc 305 tpi. I started it and the car kicked up, almost stalled, then reved normal. It did this a couple of times today. I got a code 33. The car then drives around fine with no other problems but the engine light stays on.
What do you guys think? I have a new fuel pump.
Thanks

Re: Code 33 on start up question

Code 33 is for the MAF sensor. I would try replacing the MAF power and burnoff relays.
