2001 sport 4x4 5.9L
Little bit of oil inside the intake ( I will have a picture up soon)
Motor runs great but will stall once in a blue moon when put in drive. When I take off down the road it seem like its lacking in power and has to really try to get down the road. Getting 10mpg and and needs 1qt every 4000 miles. Could my oxy sensor be bad to no codes coming up

Tune done 6 mo ago
K&N air filter
No cat with flowmasters

 

Pull the throttle body, and have a look around inside the intake. if you see oil pooling at the back, time to yank the intake.

Some oil from the PCV system is normal..... pooling oil is not.

Unplug the front O2, and see if it runs any better.

 

Cleaned my PVC valve with gas and air truck drives alittle better. New one on order from dodge. And found a e fan on my lunch brake from a CTS for 35 bucks it will be a nice upgrade.

 

When you pull the TB give it a good cleaning, it will make a difference on MPG and throttle response.

 

Will do

 

i would still put a oil/water separator on the the pcv line if you are worried about oil in the intake. the separator should prevent any oil from getting from the pcv valve into the intake.
