Like 8 months ago I posted about a hi pinion 9" I found at the JY and posted a picture but didn't realize it was just upside down when I walked past it.

Can anyone explain how to or show me a link on how to clean the egr or see if it's the problem?
When my jeep is cold if I only give it a little gas it will sputter and lose power, if I give it more gas it will go away and run good. It will also idle very low and rough while its doing this if I let off the gas. What do you guys think It is? Should I be looking at the egr?

Easiest way to remove a o2 sensor? This is not for my Cherokee but assume you guys know some tips to help get on out. Its in a 02 eclipse spyder manifold.

with an O2 sensor socket. Get that sucker nice and hot before you even attempt it. Some vehicles just the heat from driving it hard will do it, mine I had to take to a shop and they hit it with an oxy/ace torch.

Valve Opening Test
1) With engine at normal operating temperature and at idle,
rapidly open and close throttle. Open throttle sufficiently to obtain
at least 1500 RPM. Movement should be noticed in EGR diaphragm.
2) If diaphragm does not move, probable causes are: faulty
vacuum signal to EGR, defective EGR diaphragm or defective
backpressure sensor diaphragm (if equipped), or leaks in vacuum lines
or connections.
Valve Closing Test
1) With engine at normal operating temperature and at idle,
manually depress EGR valve diaphragm. RPM should immediately drop,
indicating that EGR valve is not leaking and had been properly cutting
off exhaust gas flow at idle.
2) If there is no change in RPM and engine is idling
properly, exhaust gases are not reaching combustion chamber. Check for
plugged passage between EGR valve and intake manifold.
3) If engine idles poorly and RPM is not greatly affected by
manually moving diaphragm up, EGR valve is not closing off exhaust gas
flow. Check for carbon between pintle, leaking EGR valve gasket or bad
EGR valve.

Started my jeep today after it had been sitting a few weeks(storing it until it turns historic in January). Started up fine, without a jump. Impressive.
However, after about 5 minutes of idling the jeep changed tones. I walked over to it to find white smoke pouring from the tailpipe and a horrible idling sound. I also heard a knocking noise that speed up if I revved it up. I shut it down 2 minutes after it did that.
Motor swap time?
