Hey guys. Just changed the flex plate on my 1998 xj classic. When i got the jeep back together it was hard to start, and once itd finally start to turn over, itd either stall or stumble on its face and then stall or run but have a terrible miss like its ready for nationals. The jeep has no power to it and wont rev up normally unless you peg it on and off repeatedly to get the rpms up it will idle without the accelerator being pressed but terribly any ideas? The flex plate i installed has a part number of z339? Its a first for me of replacing a flex plate. So im afraid i have done something wrong in the installation. If there is a wrong way of installing i havent a clue... but help would be appreciated. First thing i did change was the cps since that was a recent job. Figured maybe since it was new that it went bad on me again like a dud would. But installed the new one and it still had the same issue. I hooked my scanner up to it and it says loss of crank or bad circuit. Any help would be appreciated.
