Hi all. I have a 7.3 psd that i recently put a set of injectors in. It runs worse now than it did before i ohm tested the uvch last night and all of the injector pins at the main 42 pin were 4.5- 5 ohms i get cylinder contribution codes for cyl 1 and 2 so i swapped the #2 for #6 now i get cyl #4 contribution code and the idm code P1316 im at a loss. What should i check next. With A.E it shows icp at 472 and ipr at 9.5%... Will and icp sensor cause this or a cps ? I have the grey one. Will the uvch do this ? Do thos readings look normal on the uvch i thought anything above 3.5 is reason for concern. I have 1 injector making a loud knocking noise which i also moved cylinders with and it followed that one as well. I am getting a few replacment injectors to put in to get rid of the loud one but what are your guys thoughts.

 

were the injectors new?remanned?used?

 

Have you run it 50 miles or so to get the air out of the oil and fuel rails? The ICP and IPR look good to me.

 

They were reman's from orillys. Very expensive but after reading on here i guess its not uncommon to get a pad batch ? I had them order a complete new set just in case

 

Im going to change the noisy one today swap the #1 with #3 to verify that one and install the new reman they ordered. The rest wont be in tell sat

 

were they torqued properly and as fizuka said run to get the air out?did you have any cup issues?have you compression checked the motor?

 

I didnt run it that long just around town for a little while but i would thnk if it were air it would improve while driving i have had no change and compression check will be done today i just didnt feel compression would be an issue there is very little blow bye out the breather if any at idle and the cups looked great

 

Ok so after alot of injector swaping and exchanging at the auto parts i finally have a smooth idle now im getting an icp code 15v koeo 16-18v idle. While driving it will shoot up to 3000 then drop to 17-1900 at wot while ipr is 64%. Im going to get an icp sensor i think its bad and its full ov oil but do you guys think the pump is shot also ? I didnt have these codes before the injector swap and with the valve covers off im getting oil shooting out from the spacer under the solenoid with the little hole ? Could this be the hpop leaking from the poppet droping my icp
