Any throttle movement forces .88 lambse

Unread postby beuchaw94gt » Sat Jun 10, 2017 9:18 pm

So i am having an issue where when i drive the car any throttle tip im at all will force my lambse to .88. I am commanding 1.0 i turned off adaptives and cleared my Kams. I also put it in open loop. I can figure out why the computer is commanding it to be so rich. I never had this problem til about a month ago. before it was completely fine. I changed nothing so i dont understand. if you guys hving any idea please let me know. thanks in advance

make sure your tps sensor voltage, maf voltage, and perload are functioning correctly

You were right the perload was more than double load.
