So the 4.0 in the white ZJ seems to stumble at random times while I'm driving it. It feels like a power loss, such as when a coil is going out, but it always stays running. If I floor it, it builds rpms and runs fine. Sometimes it will run fine after doing this, sometimes it takes two or three times of flooring it and then its fine.
I've replaced the following on it:
cat
battery
alternator
serp belt (was worn out)
plugs
wires
dizzy cap
rotor
ran a new ground from the motor to the firewall
tps
iac
pcm
Only thing electrical that I can think is the pick up on the dizzy...well and the map or whatever that one is, it hasn't been replaced.
It does it more right after start up with in a mile. Warm or cold.
