Hi there my v7 is popping/backfiring at idle. It more sounds like a miss. But runs extremely well when driving. Idle rpm stays at 1.5-1.8k. And idles quite smoothly. The pop sound is definitely coming from exhaust side. Have replaced IACV and gasket. Car hasnt been started in 6 months, however now it is on low boost tune atm. Because of this issue.
Any one else experienced this before?
Ohk thankyou kiwi fozzi. Is bore washing extemely bad ? have only cranked it afew times... and to prime turbo..
Also could it possibly be that my maf sensor is now in a 4" intake?
Just tryed to start my v7 sti after about 5months of building it. Its cranking and sorta running on like 1or2 cylinders but not fully firing up.
All ive put in that could relate to this are:
Hks 660 injectors
Tomei fpr
Deatchwerks pump
GFB ebc
New heat 7 spark plugs
3 guages.
Any help please my tune date is coming up...!
