Rough Idle After Coolant Flush

[sampson2269]

I had my coolant flushed today and now my truck is idling rough and sluggish to get going. Temps were normal though coolant 193 oil 197, any ideas?

Did you do the flush or have someone do it. Check for disconnected wires... any codes showing?

Yea I agree, check the vgt plug. Your not smokin are you?
You might look at all your injector plugs and egr that's pretty close to the thermostat.

Good advise I'll check everything once its stopping raining/snowing outside. Ya I had a diesel shop do it close to where I live. We did a chemical flush which might have been a bad idea but I figured with the coolant filter being on for 10000 miles now I might be ok. And it isn't blowing any white/blue smoke so I dont think it plugged the oil cooler. I talked to one of the guys at bpd and he thinks worst case scenario I might have a injector going bad.

Keep a eye on your coolant filter, I would take it out after 100 miles or so and cut it open to see if there is foreign debris in it. If it looks pretty dirty I would recommend you to
do some more flushing with the block plugs out to make sure you don't plug up your oil cooler.
I just finished a coolant flush on my own truck and I used Cascade dishwashing liquid soap and that even worried me. I flushed out 3 times with DI water and it even loosened up some stuff. All seems well and now have blood red coolant.

Keep a eye on it though those acids really do some heavy cleaning and you don't want to let stuff loose in cooling system plug up the sacred oil cooler.

Only a matter of time if you dont check your fuel pressure, for piece of mind. Do you have the blue spring update?

Sent from my phone that somebody didn't help me get.

Sure do with an edge cts monitoring fuel pressure.
