bpr7's makes car die?

[sacline]

So i have been messing around with different spark plugs.. i am all stock besides the "free mods". I have had bpr 6 in it, denso irridium and now i recently put in bpr7's in. Wen the car is warmed up and i come to a stop.the idle dips real low and sometimes dies. After i go wot and coast her out the car dies..is this because the 7's are too cold for my stock setup?

Iirc they are used in applications pushing 18psi+. But are you sure you gapped them correctly?

Just re-posting his pic. Developers like to convert ASCII symbols to be HTML compliant and it messes stuff up.

Is your BOV vented?

Nope. Recirculating like its made to be stock.

Have you adjusted your base idle? Checked timing advance? Do you have a lightweight flywheel? Checked the MAF to confirm it is within parameters by referencing the factory service manual?

It's not your plugs. Even then, 7's aren't necessary if you are a stock setup below 18-22psi.
