Hey Guys........im back with another question on my 2006 Lt3 3.9l..........Does anyone know how many fuel injectors i have i need to buy new ones car is running horrible still i think it could be throtle body but not sure

 

I'm about 90% sure that you have 6 fuel injectors on your vehicle. Most FI V-6's have 6 injectors. I'm sure that if I'm wrong, someone here will correct me very quickly. Good luck!

 

I'm gonna have to say 6 also....

wow 6? geezz is there a way to tell witch are bad???

 

not sure, but if you know what you are doing then take one out and replace it with another and see if it changes, kinda like swap them out and see if there are any changes? I'm not sure, but that is what has been posted here before that I recall. Hopefully someone more knowledgeable can help tomorrow.

 

90% sure? I like your statistics :P

OP - you have a 6 cylinder engine. Each cylinder has 1 fuel injector.

What makes you so sure that the fuel injectors are bad though?

Your car is fairly new. Was something done to it that caused the injectors to clog? Is your mileage super high for a 2006?

Also, you know you can have your injectors professionally cleaned instead of buying new ones (costs about $20/injector iirc).

Generally if one injector is bad, it will cause an issue on a particular cylinder. Like montecarlo3831 posted, you can switch the injector on the problematic cylinder to a different cylinder and see if the issue follows.
