Injector problems

After installing my Scan gauge and doing a few CCT and buzz tests, I have come up with codes:

P0281
P1316
P1277
P1276

After doing a few tests the codes P1316 and P1276 popped up. The ones for cylinder 7 stay constant.

I will try swapping that injector to a different hole.

Any insight ? The injectors have maybe 1200k on them

That is a lot of km's on a set of injectors...

Swap 7 with 5 and see if you get the same code.

Are you having idle issues or running rough? It could be armature clearances. If the armature is hitting the solenoid it could be causing those codes.

this makes me want my scan guage even more lol

1200km is brand new almost...

Nate is does run a little bit rough, nothing to extreme but I can notice an irregular idle and it seems to be intermittant.

I pulled the valve covers off and ran it and unplugged number 7 and it ran worse. Plugged it in and it ran fine but still fails buzz test and CCT ?

Like stated injectors have 1200km on them.

the high mi. statement was from your original post of 1200k. think it was mean to be a joke...
