06 4.7L commander
Well My rpms have been hunting a bit and the idle is not as smooth as it used to be, I have 84,000 on the clock with original EGR and PCV And IAC and TPS should I replace all of these and my plugs are due for a change I was thinking champion iridium, all maintenance has been done regularly synthetic oil and such. My manifold is leaking too so that will be fixed also. Where is the egr and pcv on the 4.7?
Also I have this strange whistle any time on gas it comes and goes ideas???
Thanks a bunch Im on the jeep commander forums and thought id come over here
