My Car Is Missing

[XXE-R32]

Ok i got my boost problem sorted, ruinning back to stock again, but now the car is missing down low, even at idle it misses now and then. Would a new set of spark plugs fix this problem

any ideas

If your car is missing i'd call the police.. try and get it back man.. coz having no car is a bummer.

Welllllllllll i think its missing, even at idle its fine for like 20 seconds then it will miss once then again in 20 sec time, then under load it misses then goes hard, im confused

Come to think of it, its kind of doing the boost cut or feul cut thing. it is boosting ok, but just sperts and carries on. Then at idle it just misses every now and then.

the only thing i have done is put a front mount in thats all

its a common problem. Its the valve seats. What happens is you bring a car like a skyline to Australia and run it on the shitty fuel and it valve seats get dirty and every now and then a valve doesn't seat properly temporarily losing compression on that stroke.

The valves slowly rotate... therefore every now and then not seating properly.

if you want it to go away, take off your head and get a valve seat grind.

Other than that, just leave it.
