Thanks,

Check the harness for chaffing,

 

I looked it over and there was nothing,also when i clear the code,it doesnt come back.

that's your cylinder #4 injector, maybe it got stuck? if it happens again you know something is wrong with that injector, but your CEL pops on the second fault so there was 2 instances.

 

Yeah,it only came on once and then it never came back,i had the injectors cleaned but i think they are faulty and the thing is,these injectors have only 600miles on them

 

maybe clean the injectors, if you happen to pull off the rail check if the seals are still intact and not floating around. sometimes CEL pop on once in a lifetime and your just like 'wtf?' delete it and you never see it again.

 

Once i cleared them they never came back but the cars rpm's are all over the place at idle,have a friends set of brand new injectors that he said i could try so that i can eliminate the injectors if thats the problem.

 

well then sounds like #4 is taking a nap. Your on the right track.

 

Well,changed the fuel filter,new plugs,new injectors and harness and its doing the same thing,im guessing now that the timing is off,any other ideas guys?

Throw it away already!!!

 

The injector control circuit goes all the way back into the PCM. Can't rule out the fact that the PCM may be the culprit, especially after all the stuff you've changed.

Do you have any LSJ friends that would let you borrow their PCM + flash it with your HP Tune?

 

But wouldn't the code always be on?ill ask one of my friends who I tuned and see if he will swap pcms with me.

 

Its hard to say for sure, but it just makes sense given all the stuff you've replaced. Text me with whatever you find.

 

Will do Steven

 

So I'm getting this code too ... I've switched injectors around and everything was fine for a week but then it started popping up again... I did notice that the hard seal around injector #4 was a little loose... I cleaned it on that same day but code popped up again... I'm waiting for other injectors and harness to arrive

 

This is what I found.
