97 lumina pcv valve

i am new to this forum. i have a few question. i own a 97 lumina 3.1 L. i was wondering what could have cause the ses light to come on. i hit a curve thanks to this idiot who cut in front of. the entire under carriage of the car hit the curve and the ses light came on. also i tried to changed the pcv valve. the pcv valve was stuck in the elbow grommet which broke. i had to replace the hose, the elbow grommet, and the pcv valve. now on take off the car stalls. i am some what positive that i hook everything back to gather. also when i was take the old off it broke. it didnt matter i had a new one on hand.

You need to get the DTC's read.

like GMtech79 said, you'll have to get the codes pulled. If you live near an Advance or Auto Zone, they will scan it for free. Get a printout, or have them right down the codes and post them here.
