It's all messed up, JB4 map 2 stock gapped, with intakes only.

Yeah that was plugged in, but does the engine have to be turned off? I'm gathering it does that is how it an external obe code reader works you don't turn the vehicle on you just put it to the accessories I'm sure this probably works the same way can't read the codes unless it's an accessories and not turned on.

 

Yeah well it seemed to run good for the first maybe hundred miles after that is what I noticed the power seemed to be a little down, then the searching on the gears seem to be a factor, but now what I think it was doing was misfiring and then shifting gears or downshifting because of the misfire. I did send them a map 0 and map 1 last night so hopefully they will see it this morning.

 

Dear Lord that didn't make any sense what I wrote there. What I meant to say was they are stock Gap stock plugs, I ran it in map to I only have K&N intakes

 

What I was saying I have not touched the plugs at all. I installed the jb4, and O2 sensor wires. And that is it

 

Yes I am crossing my fingers that is the only problem.

Got it

 

So why is there 3 wires and 3 prongs on the harness side that runs to the OBDll yet only the two wires on the plug-in portion that goes into the jb4, and yes you can plug it in multiple ways it's a square so it will go in the wrong way somebody like to tell me why this isn't mentioned anywhere as to how these are supposed to be plugged in?

 

Ok got it, thanks!!

 

I did the same and my car barely ran. It was my plugs, new gapped denso's from Burger and everything runs perfect now. No hiccups, transmission.searchimg, power loss, all of it was because of these piece of shit stock plugs. I really thought it was something else, I had no idea plugs could cause so much problems. The first 100 miles must have actually caused them damage. Because even back to map 0 and having the jb4 removed the car would barely run after that.
