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...

Welp, sounds like I have a few reasons to take the manifold off. I no longer have the shaft so I'll just fill the holes with JB putty

Damn thanks a ton for all this info! I would leave the manifold as dual runner and do the gasket match like you did so it sounds like I won't have to touch the head which is great. I'm also very interested to see how my throttle body gasket will line up. My vtcs is already deleted but I didn't...

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...

ATP catted DP, I know I usually should not be concerned about short spikes in STFT but they seem to consistently happen when I'm in boost with partial throttle which worries me.

battery is just a year or two old, I replaced it when the original battery started to die

LTFT being at -7 is probably because I had my injectors cleaned shortly after my PD tune was completed. I showed logs to the tuner and he says the LTFT is nothing to worry about. For leak testing all I've done is have a friend blow vape clouds into the intake, intake manifold and other random...

I've checked for leaks a number of times and can't find any. LTFT is always between 0 and -7 The STFT spikes where I'm finding it hard to control the throttle usually happen in 5th gear during light pulls. I usually wait till just under 4k rpm to boost in 5th

Most of the time my car runs on the richer side of normal, however there are some circumstances where my STFT will climb to +25. If I'm very light on the throttle like driving through a crowded parking lot, STFT will slowly climb to +20 or more and will stay there until I let off or give more...

Well then I'm really SOL, that actuator is broken. And I need to pass emissions which means getting an updated map with all monitors turned on, I can reinstall my EGR but still need to do something about the code my VTCS delete will throw

That part is unfortunately lost, was hoping someone knew about the kit I heard about. But if I found that black box that sits on top of the manifold could I just plug it in and leave it dangling? or would I have to hook it up to the plunger thing?

I dumbly have vtcs and egr deleted and need to pass emissions. I have heard there is a kit sold that dupes the ecu into thinking VTCS is still there but I can't find any real info about it. Hoping someone can point me in the right direction. I'm not very mechanically experienced so I don't think...

Ran the car for a few minutes and it held vacuum for at least 30 seconds afterwards. One other thing I just noticed today is I could not suck air through the booster vacuum line, but I could after running the car. Could this indicate a malfunctioning check valve?

messed with the car some more today, my brake booster seems to hold vacuum no problem, I disconnected the brake booster from the intake manifold and the car still sputters. Also, if the car is not fully warmed up then pumping the brakes does not mess with fuel trims/afr nearly as much. But at...

LTFT is usually close to zero at idle, and -7 at the most when cruising. I'll double check that ground for sure

I just recently noticed that if I pump the brakes multiple times while idling, my AFR will climb up to 20, STFT to +25 and the sputters become more noticeable. I checked for vacuum leaks around the brake booster (and everywhere else) and couldn't find any but I think this confirms my problem is...

I'm having a similar issue as well, a sputtery idle and p0300 shows up every few days. My rpm also jumps up a bit when i shift into neutral. What rpm does your car idle at? Mine idles just below 1000 rpms, it used to idle lower before all my mods, not sure if my tune makes it idle higher or...

My genpu has a rough idle where it makes a small sputter every few seconds, I also get a p0300 random misfire code that comes on every few cold starts. I have done everything I can think of to fix this issue. I've changed the spark plugs, cleaned the valves, rebuilt the HPFP, changed the o2...

yep!

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...
