Q: Fluctuating rpms stalling acclerating

asked by on July 28, 2016

My TJ has been losing power with fluctuating rpms, stalling, and not wanting to move when I accelerate. All of these things happen unless its warmed up. But the rpms keep fluctuating. Ive cleaned out the TB, replaced the spark plugs, cleaned the IAC, put in a new coil in, new distributor and a new muffler. I get a code for an Evap obstruction - not an O2 sensor. What could the problem be? Need help.
