took the cat out. maybe have some issues, idont no

[mike243]

ok guys i got a stock 2005 f350CCLB. only mod i had befor taking the cat out was the muffler delete on the stock exhaust..

now i took the cat out so my exahust is straight piped( sounds amazing) but i had a little issue.. now i dont no if its just my luck that it happened or its because of the cat being out,

problem.. drove into town and stoped at a light, went to take off and the truck wouldent go past 1500rpm and it started todump out white smoke.. it did this twice. so i drove it around town somemore and it dident do it again at all, felt fine. now do i have other issues here or what?


PS. i did have this happend to me about 6 months ago with the truck not wanting to go past 1500 andwhite smokie pouring out..


one more question do i have to reset thecomputer by dissconnecting the batterys for 20 min so the truck can reset it self to the cat or what..

thanks guys sorry for the long post

I don't think it is the exhaust making this issue, sounds like when my 7.3 used to get low on oil.. it would do the same type thing, lots of smoke no power. But i don't know about this issue, these 6.0's are so computerised it is hard to say in your case.

yea i just took the truck for another drive and let it idle in the parking lot for a while. runs fine.. but im worried about the white smoke thing. gunna go check my coolant level

Sounds liek your EGR cooler is probably acting up or egr valve also. White smoke means coolant is getting into your exhaust or cylinders.

Yeah, I would think more getting into the cylinder. If it was the egr cooler leaking I would think it would happen frequently. Jack the back of the truck up or park it on a good slope with the nose down hill. Then pull the egr valve and see if you have any coolant in the intake. If so your egr cooler is bad. Do you have any idea what your ECT and EOT are when this is happening?

By the way, it doesn't have anything to do with you removing the cat.

ok thanks guys. the truck is running just like it should... this white smoke happend prob a total of 5 times. the last time it happend i check the egrcooler and found nothing that look bad..

could this be a headgasket problem. that is taking it time..

Yes it could but it doing that at an idle is unusual unless it is totally blown. Usually as a head gasket goes it will show up during a load like romping on it or towing up a hill.

if you take it to the dealer and expect any help under warranty, you got to put the cat back on... they are ridiculous, i keep my CAT in my in bed toolbox....lol

but on a side note the truck is running great and sounds awesome..

Not necessarily. I had my head gaskets and studs, oil cooler rebuild, EGR delete installed, STC fitting and dummy plugs upgraded, updated HPOP screen, all done under warranty and my truck went in with 4" turbo back straight pipes hangin' off an 03 turbo. You have to find a mod friendly dealer that wants the work.
