Ok my check engine light came on again the other day? It happens once and a while about five or six mins after hard acceleration. My main question is what kind of scanners are good and where can i find one/purchase one? Also can i use it one more than just my firebird i.e. pickups wagons ect? Also i plan on getting a 350 way down the road will it be alright with different engines? And i did do a search didnt find anything that i was lookin for.
