zjorvis97:
my 5.2 will idle fine, but as soon as i try to push the pedal down it jumps all over and won't run a constant RPM. 

calvynandhobbs:
Could be a lot of things from vacuum leak to throttle position sensor. Are you throwing any codes?

zjorvis97:
no codes. The vacuum system was fine. I replaced the IPS. I noticed today blueish white smoke and it smells like gas. If i remember correct that means i am running too rich? idk, but this jeep is frustrating lol.

WillC:
Bad injectors?

rocket:
blue smoke is oil.  I speak from experience, i burned at least a quart a week all through high school!
