ecotech

Ok i feel really really stupid asking this but i was given my 1995 cavalier. its 2.2 liter. how do i know if its an ecotech or not. i see it mentioned a lot on this forum? If you could help me out this would be great! Can sumone please help me.

are all 2.2 liter cavaliers ecotech?

they didn't start using the ecotec until late 2002. There weren't many in 2002 but I believe that all cavaliers from 2003-2004-2005 have it. I have the ls sport coupe but I think it is in all of them now

ok thanks a lot
