White Smoke w/ Looney Cold fix installed

[huhner5]

When i start my truck in the morning (bout 40 degrees out) with the looney tune installed it just gives a puff of white for like 5 seconds....... When i changed the tune to the Looney w/cold fix it starts easier but it puts out an extreme amount of white smoke for atleast 4-5 min... IS it suppose to do this? Runs fine still.... no white smoke after it warms up.... just kinda curious

If I start my 04 with street smoke tune installed it PUT PUT PUTS out black smoke, no white though

[huhner5]

It still smokes alot of black after it warms up.... just have this problem when i start it in the morning..... and it isnt even that cold yet... just dont seem quite right

[BOILERTURF2387]

True. My only PUT PUT PUT PUTS when its lower than 45 degrees or so. After about 2 mins it goes back to regular idle

[huhner5]

Does any body else have expeirence with any of the cold fix tunes? This problem?

[huhner5]

Can anyone help with my question.... just kinda wanna know if this is serious or if i did somethin wrong installing the tune.... Thanks to any info in advance

White smoke is unburnt fuel. Call your tuner and see what they recommend.

I had a diesel tractor a few years back that did the same thing. The rings were shot. Once replaced no more white smoke.

i also get the black smoke when its cold. it also runs like its got only 2 cylinders. only for about 2 minutes tho. it drives me nuts. i talked to dj and he said its a lazy injector. i then talked to my diesel mechanic and he said its not. i wish i knew the answer. if anyone knows please help us .

also do you think we could use the high idle mod to get rid of it ? and does the high idle mod idle high all the time or does it go back to normal idle after its warm. on the sct xcal that is.

I would say you either have a lazy injector or 2 and you dont have enough fuel pressure

Had same problem with mine 4 lazy injectors and needed a new fuel pressure regulator becuase it was putting out the minimum psi, after it is warm it doesnt take as much psi to ignite your fuel because the cylinder temps are higher, thats the explanation i got from my mechanic anyway
