1995 XJ. 4.0 AW4, the usual outfit for a 4dr XJ.
Has 'moments' as the woman likes to call them. As you're driving (any speed/rpm. Issue is not dependent on these two factors) it will lose RPM momentarily, bounce back and then die. No sputter as if losing fuel, seems to be more of an ign problem. I've replaced the coil dizzy/cap and rotor assembly when I first diagnosed a short to ground within the distributor. MOST times it will require a few minutes to sit, as cranking it over results in nothing. Sometimes I smell unburnt fuel out the tailpipe and sometimes I do not. The CPS is less than a year old.
Anyone experienced anything like this? It does it about once a week, with about 4-5 days between 'moments' I have recently found that unplugging the TPS, it will fire up and then I plug it back in to continue my rudely interrupted journey.
*edit* The fuel pump is brand new, about a month old. Maintains pressure, ect.
