My 85 iroc is giving me codes 32 and 33 and when I try to give it gas it sputters or just stalls and i have to let off to keep it running. I know that 33 is for the maf and 32 is like the map or something but I dont even know if my car has one or if the code's for the baro pressure something? Any help would be awesome as I am completly lost.

I should probably say that the stock tpi intake is on but a 350 base was swapped in.

 

does this happen right away everytime or after the car warms up for a min?

mine did the same thing after running for a few seconds it would stall when i gave it gas then after a few tries it would not start for quite awhile.......turned out to be the icm in the dizzy.

 

Huh well mine does it right away but it always starts back up fine but I think I'll try that. Thanks

 

Anyone know what my code 32 is for? It didn't have a smog pump or any of the emissions when I bought it. Would that cause it? and if it does should I worry about it?

 

32 EGR open command did not change MAP sensor signal. Normal EGR flow should cause slight decrease in manifold vacuum which would change MAP sensor signal.
