Missfire Or Something On Boost.

[Stealthynsa]

hey guys i have been driving my r33 around with standard turbo and ecu with a fmic downpipe back 3"exhaust and bosch 040 pump.

its been fine but the other day i noticed after i tried to install a boost gauge when i drove it WOT underboost the car makes some pop pop noise "very quite" but i feel a quick slight power loss

while this noise is happening, so i took the boost gauge back off and turned it back to how i had it and still having the problem i havnt checked plugs yet i will tomorrow.

but basically just wanted a few idea's on what it could be so i can wake up tomorrow and get started on everything possible

Cheers

Check plugs, but most likely coil packs. Do a search, very very very very very common problem.

When you check the plugs, either put new ones in or re-gap the ones you have... (your already there-) I gap mine at 0.4mm for the high boost-

If you were just putting in a boost gauge by rights you should have only put a T piece in a vacuum line yeah??

p.s, when your putting the 12mm bolts back in to secure the coil packs, make sure your careful not to drop the front one down behind the cam gear cover cause its really f**ken hard to get it out if it falls the right way!!! LOL

Good luck.
