Hi Guys
I brought a Jeep 1996 Grand Cherokee Lardeo 4 liter in New Zealand for $500
It was running mint then exhaust after cat fell off and manifold just below after 1st 02 sensor had a bad leek.
Jeep was still running fine .
Fixed exhaust then the problem stared .
It runs fine until you idle down and seems to happen about 2 mins after start up.
All these things i have done
OB2 scan tool said 1/1 02 sensor . did this and ran for 1/2 a hour fine then back to misfires.
New Plugs and leads and dizzy .
Fuel filter and injector service .
Vac seals
Earth wires and wires

It seems ive got a common Jeep problem but ive tried everything . Please any info to get my Jeep going again.
