Replaced the plug. I'm going to borrow a boroscope from a friend to look inside. I did not think it was wise to increase the rpm from idle considering the current situation. Ceramic is fine on the spark plug. The sound is definitely coming from cylinder 3, I was recording from the drivers...

Greetings, So I have had this issue once about 6 mos. ago with a bad misfire in cylinder 3. Tore everything down pulled the injectors as I suspected there was a leak and there was. Replaced the injectors with an extra set I had laying around, installed corksport injector seals, installed new...

FWIW. I ordered my slave cylinder from Tasca part # B37F-41-920B and had no fitment issues installing on my 2008 Gen One.

If it's leaking on the ground under the front of your car, it's more than likely your slave cylinder. It's a cheap fix and only took about 15 min. to replace.

What he said ^^^^^^^^^^^^^^^^^^ I've been running DTA's for a long time with no issues and at $140 for both axles. You can afford to break them if you want LOL...

I had a similar issue. Random or specific cylinder misfires for years with no real continuing issue then came the rough cold start like yours. Then a few months ago cylinder 3 misfire became awful to the point of a flashing check engine light while limping it back home. Thought I was in for a...

I just replaced my clock spring as well at 242K on my Gen 1. Its an easy fix, only took about 20 minutes. Here's the link to the easy fix.

@Duey1083 - I installed the CST4 at about 235k. The K04 had some shaft play, it was time for a change. Very happy with the Corksport turbo.

@Duey1083. They all consume oil, I change my oil every 3-4k miles with Penzoil Full Synthetic 5w-30 and I'm always down a quart or so when I change it. You are correct about "fully bolted". All external bolt on mods. vs. built motor i.e. full after market bottom end, cams, big turbo, like...

1) 2008 2) Just turned 242K miles 3) Original motor: I bought the car with 92K miles - Runs like a dream. Little things come up from time to time i.e. Thermostat replacement, Pivot Shaft Seal, Slave cylinder etc. I do all of my own wrenching so keeps costs at a minimum for repairs. 4) Daily...

Just received a set of these for my Gen One and unfortunately one of the strut seals was blown out when I opened the package, therefore it's useless. The speed line return policy is bullshit, I pay for return shipping because the package is open. How do I know it's defective if I don't open...
