SES light and couple codes, but no limp

az335idesi · 10-20-2011, 01:21 AM

I was just cruising today and the SES light came on, figured it was due to downpipes that i installed a few weeks back. But i checked the codes, just because i wanted to try out the jb4 in-dash code reader. And i pulled 2 codes, any body know what they are??
Code 1- 29D4
Code 2-29D5

please help! THanks in advance.

Mis-fires

Weird. I didnt feel anything at all. Completely smooth ride. What is the usual fix for misfires? Or should i just delete the codes and see what happens?

Thats how they happen..had 4,5 misfire happen just when i was driving off ..SES went off car started running rough for a bit and then returned to normal..yours are also in cylinder 4, 5.

I just cleared mine and they never re-occured..clear em and see..if they repeat in 4,5 swap the coil packs to 1,2, cylinder..if you get the misfires following to the new cylinders then you know its the coilpacks..if you get 4,5 misfire again after you've swapped coilpacks then its prolly the injectors..

Its a process of elimination. Like i said i had it once in 4,5 and never re-occurred.

Good luck.

+1, same here. Mine were in 1 & 2 so I swapped coil packs to 3 & 4 and the problem never came back...that was over 3 months ago. I swear there are gremlins living in the N54.
