Also I forgot to mention im still using a mk3 o2 sensor found a 89 cut the plug and tied my plug into it. I wanted to use the mustang one but it would occupy my only lambda nut. From the same colored plugs im getting with the key on both have power and the signal has nothing. With the car...

What would a bad o2 do? What i've experienced within the last hour is: @5-6k rpms it feels I have no power and it back fires 1-4k feels fine. Idles fine Spools fine until 5-6k Ill check what I'm getting at the harness Sent from my SGH-T959 using Tapatalk

Also the o2 sensor isn't kicking a check engine light only when I gap te1 and e1 is when I get the code..... Any clues on why it does that? Sent from my SGH-T959 using Tapatalk

The green and black weren't getting power due to the hks fcd so I removed it and now the map sensor is working But other then that the car is running fine except for the o2 sensor. Will not having a o2 sensor make my car sputter a little? Sent from my SGH-T959 using Tapatalk

I have no idea which port it is I tried looking at a 1jz pinout but couldn't see a port for map or air flow meter? Do you know which port the map goes to on the ecu? Sent from my SGH-T959 using Tapatalk

Yea im gonna have to do some investigating cause I picked a used working map sensor from a good source induction performance (F&H performance) and a o2 sensor from a friend and im still getting the same codes 21(o2) & 31(map). Still running rich and back fires at 3-4k rpms Sent from my...

Agreed I personally hate the damn thing but it's in there for now Sent from my SGH-T959 using Tapatalk

Ok so heres the update.... I replaced my spark plugs with copper tops cause my old ones were black black then I for some reason was curious about my hks fcd (came with car I didn't install.... If it was up to me i'd remove it but I need a write up for it) any who I turned the dial to 12 (norm)...

Ok so I checked my ecu for any CEL and I found 12 and 21. The problem for 12 is rpm signal and 21 is o2 sensor. With 21 I can just replace the o2 sensor right? And im lost with 12 any input? Sent from my SGH-T959 using Tapatalk

I have a question about this.... I have a lamda nut at the end of my downpipe where it meets my exhaust my question is will that o2 sensor work way down there or will I have to go get another lambda nut welded into my downpipe near the turbo.... Any input? Sent from my SGH-T959 using Tapatalk

Thanks man Its a lot easier when stuff like this is simplified ill let you guys know the update when I get a chance damn job is keeping busy! Sent from my SGH-T959 using Tapatalk

Do you know for which car or part number? I have a 1jz Sent from my SGH-T959 using Tapatalk

So check the connection to the map sensor, check my o2 sensor and check my plugs for cracks.... Iight ill give them a shot when I get home thanks guys for the advice ill keep you updated. Do any of you guys know which o2 sensor I will need for my 1j If I end up needing it? Sent from my SGH-T959...

You talking about that hose that goes from the map to manifold? Yea I checked it yesterday, connected or not it does the same thing Sent from my SGH-T959 using Tapatalk

I was thinking the same thing but the wiring looks fine plus hasnt been touched. Also I tired a map sensor a mk4 and it did the same thing. I mean if I can find someone else with a map ill give it another shot. Also I forgot to mention that I have a hks fuel cut defender (came already installed...

Yea I already cleared my codes, cars been sitting for like 2 weeks waiting for ecu to come back from DM. I can try the coil packs but it seems unlikely that all six would go out, only reason I say that is because the car acts as if they all went out I cant even get it to rev pass 1-1.3k when I...

To summerize what happen in a nut shell, i washed my car, did NOT washed my engine bay at all, i drove the car for about 20 mins and it shut off when i got to a red light and hasnt ran the same since. The problem im having is my car is blowing nothing but black smoke and it wont idle by itself...

Ill let the people im riding with know about this so we can all meet up we are from the tampa area Sent from my SGH-T959 using Tapatalk

No spacers and I'm using the wrong center caps for now Sent from my SGH-T959 using Tapatalk

Ill be honest the car came that way but to me it seems to level out the car I think using 275/45/17 would "lift" my rear end Sent from my SGH-T959 using Tapatalk
