I have a '96 2 Door XJ w/ 4.0 HO Engine.
It has 223K+ miles on Orig. Engine.
Recently Replaced All Sensors. Installed Ford 4 Hole Injectors w/ New O-Rings.
New Battery & 4GA Cables (Incl. GNDs), Cap, Rotor, & Sensor Plate.
Mallory 50K V Coil. 8.5mm Plug Wires. New Copper Plugs Gapped @ .040.
Cold Air Intake & New Air Filter. Also Replaced CPS, NSS, Fuel Pump & Filter.
Ran Great 4 about 3 wks & Now it's Stumbling & Almost Dying at Idle & Low Speeds.
Runs GREAT at Highway Speeds. Just Doesn't Want to Idle or Go Slow.
Checked All Connections & Everything is Tight.
That's when I Noticed Smoke Coming from the Dip-Stick Tube!
Looks 2 me Like Maybe Bad Rings?
Also has Smoke coming from Valve Cover Breather.
Only Smokes After it Warms Up.
Any Ideas? This is my DD. Should I Keep Driving It or Not?
Gonna Borrow or Rent a Compression Tester this Weekend.
May Also Need to Pull the Valve Cover 2 take a Look See.
