Help with tune!!!!!!!!

[Jake Staton]

a truck i tuned started hazing at idle last week I have a log that i will attempt to attach. it goes from idle to 1000rpm then to 2000 rpm and then back to idle. i think it might have a cracked injector... let me know what you think.

It is my truck and we checked the balance rates and all were close except for num. 4. It was a little higher than the rest at idle. But once you got it up to about 1k rpms they all balanced out.

Here is the log

Should be a bigger file than that. I think you only posted the short cut.

That just means the ecm is no longer balancing the quantity to make the engine smooth. Above 1000 that is.

You can't check return rates above idle...

by the log do you think im in need of injectors. we still logged it at idle.
