I was planning on getting new fuel injectors for my cobalt, and was wondering what I should keep in mind when choosing which to buy. Basically I was wondering,

1. What are some good brands to look into
2. What is the main difference between different lb sizes ( 42, 60, ect.)
3. Recomendations
4. If its somethings thats easy enough that I shouldnt have a problem installing myself. (I usually am okay doing basic maintenance. One oil changes, spark plugs, ect.)
5. Anything else I should keep in mind that I didnt mention

Thanks for the help btw

 

there isent a whole hell of alot of choices out there go to zzp and look

 

Get 60 lb injectors. 42 lb usually dont last long because you will want to keep modding.

Injectors are super easy to install. There are 2 or 3 bolts that hold the fuel rail down. Undo those and pull up on the fuel rail (might take some force).

Take plugs off injectors, then the clips, then pull the injector from the rail (might take some force).

Instal new ones in reverse order. Make sure that the boots are properly lubricated (they are the grey things that go in the head. Clean all the junk out of them and the head. Make sure the injector seals are lubricated too.

 

I just got mine and it had a code saying it was misfiring in #4 cylinder. Guy at the dealership said i should try replacing the injector and that should fix it. Is that the cheapest place to start or is it better to try something first?

 

I would try spark plug
