Planning to replace all 4 Fuel injectors this weekend on my 2006 Cobalt SS 2.4 Ecotec Automatic… I know how that’s not the problem, problem is afterwards am I gonna need a Reflash to the computer??

some have told me no… some have said yes…. I don’t want to F anything up… lol not to mention paying the 200$ for four brand mew ones… any replies will be VERY much appreciated 👍

 

If the injectors that you're putting in are the same brand and flow rate, you should be fine.

 

Yea 😀 they aren’t any bigger or smaller! Just replacements for the old ones… purchased from a seller on EBay. They are New not remanufactured, supposedly OEM.
thanks much
