I have a 2007 Jeep liberty limited I replaced the throttle body, ignition coils, spark plugs,y pipe cats, all 4 O2 sensors, PVC valve, crank case vent tube, evape.purge Canister, evaporator detection pump, fuel pump and after replacing the fuel pump ran good for a short drive to gas station filled with gas and than my idle went to crap, was like getting gas than not getting gas. I removed the battery for 10 min. Ran better but now only idle in 600-700 in drive and reverse but once you put it in park the idle up down than so low it Stahl's , please help what is going on with it?

Bad gas? Vaccuum leak?
Pretty much vacuum system been replaced checked all lines no leaks either. I am thinking egr valve going to take it off clean it real good see what happens before buying new one. As for gas I buy there all the time and just put fresh gas in from there. I only had about 1/2 gallon left in when I changed the fuel pump.

Throw a scanner on it.. Look for codes and see what live data looks like .

I believe I have it figured out. It has been during all this a bunch weird things lights started flickering, battery went dead, other dash lights started coming on and off, blah blah..so I checked battery good than checked alternator and in process of putting a new alternator in I had another jeep put it in damnit it was a bad alternator too. Lol. And on the last before this I had on a scanner said fuel pump. I hope this works now
