!995 MX3 stalls when slowing down

I just bought a 1995 MX3 Percidia, it has 112000 kilos on the 1.6L engine, It's also a 5 spd. I took it out last night for it's first drive...... stalled everytime i had to gear down, stalled when i came to a stop. The check engine light came on aswell.

while i was getting it ready for certify, i would start it up when cold the fast idle would kick in, and gradually decrease as the engine warmed up and come to rest at 7-800rpm, if i kick the throttle it would come back down to 7-800 rpm. No chance of stalling, i pulled out of the driveway and it calfed, almost no throttle response (had a hard time keeping it running).
I have checked for vaccum hose broken or collapsed....none found, I haven't figured out how to pull codes out of this car yet.....I'm used to GM's this is my first import. I did notice the air breather housing under the filter is cracked....but that shouldn't mess up the mass air flow sensor? should it?

I am kind of at a loss not to knowledgeable with imports, can anybody help me out with this please
