So my 93 xj 4.0 auto with 144k miles has the following weird issues ;
Bumpy idling- rpms are fine they don't fluctuate. It's just bumpy.
On drive, when at 35 mph steady, rpms go up and down.
On drive at 55-60 it bucks- rpms stay the same
On drive at stop- it bucks rpms go up and down and at times it dies
When backing away from parking spot- R to N to D and it stumbles when placed on D
At times when it's bucking at stop, if I put it in N it's ok. Change it to D and dies. Catch it before it's going to die place it on N and it revs to stay alive.
This is what I've done to it
New CPS dealer and Vatozone (dealer mounted now)- wires-plugs-distributor and cap- injectors- fuel filter- fuel pump- fuel regulator- ECU- IAC-TPS-o2 sensor- Cat converter- cat man (was cracked)- coolr temp sensor
I'm over this!!!!!! I already spent what I paid for it!!!
