Bad Injectors??

[berto210]

sup peoples... got an 01 maxima VQ3.0 and I think something is up with my fuel injectors. I always put mid grade gas, I did a BG fuel injector flush, use BG44K fuel cleaner, and still getting this rattle noise in 1st (and sometimes 2nd) gear when I push it a little. I only notice this at a cold start only. Seems not to do that after the engine warms up. Is this due to bad injectors??? Any info would be great.

Thanks!!!

Doesn't sound like injectors to me. Sounds like valve clicking, or like something in your bay is loose... Maybe something is rattling in your exhaust?

We really can't tell too much unless you are able to describe the rattle.

^ agree with marbles.
i dont know about your v6 but in my ka when i lost an injector it made my car sound like a helicopter.

I had a similar problem like that before and it was just a loose heat sheild.
Give us a little more info on it.

this problem just came up on my car. I unplugged each injector one at a time, to see which one was not firing. found out my first one is bad(i hope). Anyone have a spare injector I can have?

If i am thinking right i might have one left got them off friend of mine that did a swap.
Hell they fit right into my ka when 2 of mine went down hill.

Well when you unpluged that one that you think is bad what happened?
Nothing? that would be a good indicator that something isnt right there.
That was my problem.

yeah, i tried tapping it and then i kicked it(jj). the other three when unplugged individually dropped idle and ran like a boxster engine so I know they were firing.
