Okay im just about at my wits end and im a week out from moab. my 80 series was running like a top but as of a month ago but it's developing worse and worse when i throw the truck in park and its at operating temp the truck will stumble and miss fire and even stall sometimes ONLY IN PARK/N nothing major has happened to the truck since this has started but everything is already just about new on her
IAC fuel injectors fuel pump fuel filter air filter intake boot spark plugs and wires the distributor cap and dizzy are new aswell the wiring harness is good and has no worn or chewed up wires and was been re protected my egr is deleted new 02 sensors new brake booster and master cyl its not a vacuum leak
As all my vacuum lines are brand new and replaced and spraying carb and choke cleaner in the engine bay has zero impact on idle
The truck idles like a top in drive and when i have the A/C on in park she idles fine aswell it's purely when in park no load she will stumble and stall i have no power issues up the hills no CEL and she fires right up weather at operation temp or ice cold
The truck is a 1993 fzj80 215k on the clock and i have checked all the grounds and wiring harnesses im at a loss
Like i said no major work really got done to provoke the issue it was running like she did off the sales lot and as long as i leave her in drive i have zero idle problems but if i have to get out of the truck i have to shut it off
Please help!
Here are the videos of the symptoms
