My power fc is mapped it's never been like this before like. Ok so my head is getting bloody melted now. I blead the rad this morning again what I done was top it up to the brim car on, Rad cap off,heating full blast opened the bleeder screw also revved it to 2000rpm could few bubble s cam out tried this twice but doesn't seemed to have worked my heating is barely warm when I have it up full.

I put a nismo thermostat in it too I'm wondering if its not opening or something the lower rad pipe doesnt be hot either well not compared to the top one? Or maybe there just still air in it

Idiling

As for the idle problems I re wired the maf and cleaned the element with some acetone I don't think it's the maf cause I only ran it in one my mates cars and was fine.

I went through all the vacuum lines no sign of leaks the boost gauge was plumbed into the fpr so I got rid of that an plumbed the fpr straight into the trottle body this has now made it idle between 1200-1500

Could the problem with the rad be causing the bad idle ?

If anyone has any suggestions of others causes be good
