- Thu Mar 17, 2011 7:32 pm #244525 Just wondering if im the only special one with this happening. To record it's happened to me twice in 2 years. why im still wondering.

When driving and kinda giving the car WOT. u feel a loss in power. u let the revs go down and the car sounds like an STI likes it's misfiring. U pop the hood to find your #1 Cyl spark plug dettached from the distributor?

Has this happened to anyone..? Lol..

Does anyone know why?

- Fri Mar 18, 2011 5:03 pm #244695 Crankcase pressure at high RPMs is building up and blowing out your spark plug wires. Pretty common actually especially if you put one of those valve cover filters on the breather tube.

Clean out your PCV system and replace the valve. You will need to remove the black box on the back of the block below your intake manifold and clean it out along with the passages. Make sure the breather tube to your intake isn't restricted. If you have a ricer filter on there, get rid of it and hook the hose up to your intake tube.

High revving N/A builds will need an aftermarket breather kit and possibly an additional breather tube added to the valve cover. Although you don't see many D series going above 9k RPM...

Pour Seafoam into your oil, drive it for a dozen miles, then change your oil and filter. A good way to flush the oil is buy some cheap oil, run it for a few hundred miles, then change it again.

Yea i unstand that. but it's just it's just a single i was at about 7k wen that happened and shifted into 3rd and that's wen i felt the loss in power. pulled over looked in the baty and seen plug wire for Cylinder #1 off the diizy cap. PCV system is there valve cover vent has the the rubber hose there that goes to the intake pipe came with the kit. It's a velocity stack filter kit from blox on there. Now i remember also the 1st time it happened was just cruising. guess it decides when it wants to happen. and that was over a year ago.. Just did an oil change to abuot 600 miles ago. it's whatever this motor is going side lined for the H2D swap anyways i was just curious as to why that happens.. Might be the cheapo wires and cap i guess. Since at advanced auto or Autozone no longer carry the black dizzy caps and have these grey shits.. along witht eh spark wires. it's whatever.. Thanks for the input Suspended.. ur the man.

and oph yea :thumb: on the seafoam!! .

So before you do all that, adjust the crimp on the end of your plug wire :thumb:


whoops :lol:

The metal clip inside the spark plug wire boot is probably smashed. Or you're using cheap wires.
