I am having a bad problem with my d16z6. Last weekend I installed a new boomslang jumper harness and an aem ugeo wideband oxygen sensor. After installing it I got a cel for my tps (code 7) . I checked all of my splices and made sure to crimp them correctly because I was getting symptoms of a bad ground ( running rich occasionally then running lean) and I got the cell to go away. Well now I have no power from 1500 rpm up and my wideband displays all dashes meaning I am running super lean. Please any input would be great this is my daily driver and I cannot afford to burn my rings out.

 

did u try resetting ur ecu by pulling battery cable of for 1 min and put it back on then give it a try

 

I thought about that but haven done it yet because I wasn't even sure if that was something that could help problems or was just an old wives tale or something.

 

Ya I reset the ecu and nothing changed, I am still experiencing the above problems.

 

So this morning on my way to an appointment after I had driven the car about 10 minutes the check engine light came on and the car began to exhibit normal behaviors . I didn't get a chance to check the cel yet but I will post what it was if it comes on again when I am on my way home

 

lol, sorry to laugh but the " the car began to exhibit normal behaviors" made me chuckle

 

Bump for knowledge. I could nor get the cel again, but I was wondering, I have an older style header andwhile installing my wideband that the bung only accounts for the first and last exhaust ports on my engine block. Could this have any effect on the reading I am getting from my wideband or not? I noticed the only times I get readings are when I accelerate a decent amountand occasionally at idle, other than that I am stuck at all dashes

 

Bump. Starting the car this morning everything seemed tobe running fine my wideband was reading Normal (12.5-15.5 range) and I had normal power for a d16.

 

Edit* that was as I pulled into gas station. Upon leaving gas station power seemed alright but wideband went back to displaying lean Under all driving conditions by displaying all dashes or the occasional 16.8- "---" .

 

Bump. Now after resetting ecu I get map sensor code same problems mentioned above tho

 

Error code 3
