I was getting p2187 and p2261 two days ago. It running real bad at idle but if i drive it it seems ok. I found out i had a o2 sensor loss. Thightened that and still running bad at idle. Next i looked for any boost leak cant find any. I disconnect maf and it seems to run smooth. So put new maf in and it didnt fix it. Now when i start it i just get misfires. Changed coils didnt help. So i tried something and opened the bov by hand and that makes run smooth at idle. Any help will work. no blow by also

 

What type of BOV are you running? And is it recirculated since you aren't running a blow-by setup?

 

turboxs to atmosphere. no blow by as in compression is all good. i been running fine till two days ago and i didnt change a thing till today.

 

Do you have a MAF relocate?

 

nope

 

i have had a boost leak like a year ago due to intercooler it not acting the same as when the leak happened.

 

Hmm...well if you manually opened the BOV and everything ran fine. I'd say your BOV is out of order. Is there a stronger spring available for it?

 

i can put spacers in it but still didnt help i even took all of the spacers out didnt help.

 

replace #1 02 sensor

 

lol just did that no difference. i havent had this hard of a time to find the problem.
