'89 xj w/4.0 automatic,np242. Heres the deal, while parked giving it just a slight bit of throttle, the engine fluxes from 800 to 1100 rpm back and forth rather quickly. It only does it in that one spot, any more throttle and it's smooth, at idle, it's smooth.
On to the next part of the problem...
While driving normally, when I let off of the gas completely, the xj downshifts fine, but the rpm's start fluxing again, until I get back on the gas. Replaced the TPS, checked the idle speed motor, all fine. The funny thing, while the RPM's are fluxing, the voltage out of the TPS remains the same.
PLEASE HELP.
