What would an injector do with using coolant???

 

Your coolant is being used? If it isn't leaking out then its going somewhere. May very well be a blown head gasket. An injector can cause a lope, but so can other things. I have a lope, traced it down to an etched injector connector tube.

 

mine sounds like its loping when i started it this morning in 24 degrees and it went into high idle. also was puttin out some white smoke. then agin its cold and my friends do it as well

 

How much coolant is it "using"?

 

mine lopes all the time.send them out to be tested.

 

Try to leak down test the cooling system hot like you would a Subaru first.
Try to also find an exterior coolant leak and test oil for water and fuel.
A small coolant line roughly 5/8 in behind the turbo often leaks and sometimes looks like oil that it carries from the rear main.

Any smoke? Tiny champagne bubbles in the coolant when you bring the RPM up to about 1500 or so? Making oil/chocolate milk?

 

I believe there was a bulletin put out to replace this said 5/8 coolant line. The new line should be a steel braided line, the old one was rubber if my memory serves me right. There was a post not too long ago about this but I cannot seem to find it. Hot cocoa sounds good right now...

 

No external leaks just bought it used, coolant overflow bottle was empty added a gallon to it i will pressure test it tomorrow at work i ran cetane booster in it this weekend thinking it may be a possible stuck injector seemed to stop loping not as bad as it was hoping the pressure test passes tomorrow thanks for the input if it is an injector i will be upgrading to 50 Horsepower injectors and an intake :drool2:

 

Pressure tested it today at work found coolant line left side looks like to somesort of cooler it has been replaced before the wrong way with cheap worm clamps, Headed down the street to dodge to order the line or pick it up if its in stock, oh yeah my belt also shredded a rib this morning... got to pay to play

 

mine only lopes when its real cold and goes into high idle. is that ok? runs fine never lopes at normal idle or anything

 

Does my 05 have high idle? and i found a hillbilly repair done by previous owner 5/8" cooler line to the torque converter cooler was leaking properly repair at work today plans for coolant flush and thermostat this weekend thanks for the help fellas

 

I'm just wondering if it's normal that mine lopes when it automatically goes into high idle when cold

 

yes the lope at high idle is normal.

 

Ok cool. Makes me feel better about it

 

Yeah your 05 has high idle, also has the manual high idle.

 

How do you function the manual high idle?

 

For auto high idle when coolant temp < 200*F:
Ambient temp < 15*F, ramp up to 1000rpm as soon as start the truck.
15*F < Ambient temp < 32*F, ramp up to 1000rpm after 2 minutes idle.
