GEN 1 High rough idle and misfire, etc

That might be the front diff vent hose laying there, usually they are fastened to the master cylinder.

Well that solves that mystery.

And found the intake (6.2L cover) is cracked so that might explain something's .

Boy did I buy a ****** up raptor

Look at it this way, you are fixing stuff, nothing major, when you are done, you will have a very reliable truck. Obviously the previous owner didn't have the now how to fix it properly. There are a talented group here who will lead you in the right direction. We want some damn pictures of stuff, that's all we ask in return, lol. Post some pics of your engine and stuff

Black Duct tape!!! LOL
Honestly, can't hurt anything.

Then get a Tune, and a new Cold Air Intake.

Sorry late reply. Went through all the spark plugs and wires besides the passanger front, mounted the spark plugs properly to the valve cover, had the battery on trickle charger (battery is bad) and found the crack in the intake box which ill buy a new one later . Truck runs a lot better only has the slight stutter here and there and runs a lot smoother . I think the battery is causing the issue tho .

Get the Odyssey Battery, it's pricey but it's the best!!!
And you need the extreme with all those lights. LOL
It's the only one that has 930 cca. amps and made in the USA!!!
There are threads on this forum for discount and good places to buy them from.

Also while we are electrical, check fuse #27
This is the infamous fuel pump fuse issue, check to see if the truck had the TSB service done.
Plenty of threads and posts on this forum for more info.
It evolves a fuse relocation kit.
Or at least change the micro fuse to a mini.

Sorry to revive a dead one but I was reading this thread and noticed some similar described issues with mine and wanted to ask this specific question. Surging idle, intermittent misfire with fouled lower plugs and stalling. Today I found a 2013 throttle body AL3E-9F991-CA not the now impossible to find AL3Z-9E926-A that the 2014 Rap calls for. Any thoughts on this? Would it potentially cause weird communication between lead frame/PCM etc? I am having the retarded stall for no reason thing as well.

One day with the truck at optimal temp, A/C on and my son trying to finish a much-needed nap, truck just dies. Low OP light etc. due to the stall. I want to pull intake and spray it out check for sticking I guess.
