    Loose steering rack?

    Was looking for the source of a clunking/popping sounds I have going over bumps, I get the front of my car in the air and check the wheels for play, there is a bit of play when I grab a tire and shake from the sides. However, my tie rods and ball joints all look fine as far as I can tell, and...

    Modding stock intake manifold

    My gen 2 is the first car I've really worked on and I have some (potentially dumb) questions about my intake manifold that I couldn't find the answers for. If I do a gasket match on the manifold does that mean I also have to port the head? Would porting the manifold require a retune? The...

    Too little chain tension?

    I'm part way through replacing my timing chain and vvt, I just torqued the cams and afterwards was able to fit the locking plate back in with some coercing. Does this seem like too little tension? It feels like there's a tiny bit more tension when I take the locking plate out. If I need to add...

    Chasing a rough idle

    I've had a slightly rough idle for a while now, no codes or rpm fluctuation, but it sounds and feels like a small sputter/pop every few seconds, only when fully warmed up. 2010 with 62k miles, injectors and valves recently cleaned. Logged HPFP pressure after turning the car off and pressure only...
