HPFP??

creaminz · 03-28-2010, 02:09 AM

While having little fun with M3 on freeway, I got SES light right after doing WOT.

10700 - No definition for this one
10705 - Misfire Cylinder 5
10706 - Misfire Cylinder 6
12223 - Fuel Pressure at Injection Release

If this is sign of my HPFP failing, it really sucks because I just installed ar dp few days ago

would have been nice if this happend before the dp install.
I recently replaced spark plugs.

Any thoughts?

Okay did some search and looks like top 3 codes relates to bad bank2 O2 sensor. How hard is it to replace it? Any DIY for this?

It's probably just your car adapting to the downpipes, I threw some codes initially. Going WOT probably just caused it to happen sooner. I could clear them, and see what happens in a week.

Thanks for the advice, I will clear the codes to see if they comes back again. Did you throw same codes as mine?

I got similar codes, I can't remember which ones, but they had to do with the O2 sensors and misfires. I got the 1/2 engine light once a week after the DP install and have not had an issue since. I think you will be fine.

Hell, if it makes you feel better, I just had my car in for a HPFP replacement with DP's on the car and they didn't even notice them.

Also if you have a BT....you could always clear the lamda adaptations for safe measure.
