Timing correction issue on a single cylinder...

Hey there,

Ive noticed recently that under part throttle cylinder 4 has been pulling timing up to -10* at about 35% throttle. Im not sure where to start really at eliminating the problem.

I haven't really felt any major dip in performance but a recent log shows that @ WOT in 3rd gear the timing is being pulled from #4 up to -4* only on that cylinder.

All of the 5 remaining cylinders look clean all the way to redline with zero timing correction. Id like to get rid of the issue. Ive pulled the plug from #4 and it looks clean (NGK 1 step colder plugs). What should my next step be in troubleshooting this problem?

Can you post logs?

I'd imagine this could be injector related if it's a single cylinder issue.

I would swap injectors around and see if your timing issue follows the injector

Tiago

Can you look at my data too?

i think my cylinder timing (1,4) correction goes upto -3.6 on the graph called warm4thgearpull.

If you kindly can have a overall look to see anything i should be concern about.

Thanks, it just im not getting any reply on the cobb post.

OP save your data log and sign up on datazap and upload the file then share URL.
