Back again...
Had another car for a while, but is trying the Cherokee again.
Still the same problem:
Dies for no apparent reason. But only when letting go of the gaspedal, or keeping the car running easy in about 11-13.000 RPM. Easing on the gas pedal will kill it also.
But as long as I´m accelerating it runs fairly OK ???
It also has an extremely "jerky" idel and sort of jumps forward when placed in "drive"
These are the things I´ve changed, replaced, or checked. (swapped things with a friends -89 cherokee to rule out some problems)

TPS
Flywheel sensor (CPS?)
EGR valve
Fuelfilter
ignition module/coil
sparkplugs+cables
rotor+cap
fuel resistor? (white ceramic, found in inside fender, drivers side)
battery
intake manifold

Sometimes when starting her up, she doesn´t run on all cylinders... I´m totally lost, any ideas?
