Mass air problem
 

Changed my 88 from density to mass air
the problem i am having everytime i shut the car off the restart it runs like crap.when restarted it takes about 5 mins to run properly.it's almost as if the ecm has to re-learn the idle.
Just wondering if anyone has had this happen or any ideas.i will be going threw the wiring again and trying to find another module to try.
Thanks
