In my case, the car was sitting under a covered car port for several hours before taking the quick trip to subway which was literally a mile away from my apartment. I ended taking the plunge and cleaning the Stillen intakes last Sunday. It was pretty easy. lol I definitely found out about the dealership not cleaning them filters despite installing them. The filters were definitely in need of cleaning with large black spots on 50% of the surface of one of them. I also cleaned both MAFs. The car definitely runs smoother. Haven't had any repeat issues. Knock on wood. It seems this occurrence is random and rare for some and more frequent for others.

Change the oil every month? How many miles do you drive her per month?

Would you consider aftermarket CSC+clutch if this one fails?
How much did ECU replacement cost you if out of warranty?

If you're having to pay out of pocket, consider the ZSpeed HD CSC or the Z1 CSC Delete Kit. Specialty Z also has a rebuildable clutch kit with a tilton CSC.

You won't have to replace them again. Just the CMC, which is A LOT cheaper.

Whoa 300k... dude that's pretty decent I've always heard the HR's were tough. Soo yeah as for getting your moneys worth you have without a doubt. I am only at 18k and haven't had this issue yet but if I were in your guys shoes I would do these things in this order. I have always been a believer that if your trouble shooting start off cheap and work your way up to the expensive stuff.
1. Get some electronic cleaner and hit the MAFS
2. If you have access to a smoke machine use that to find if there is a vacuum leak. if you don't, and want to stay cheap about it get a cigar and some sort of tube or like 3 or 4 toilet paper rolls tape them together take some puffs off it and blow into the engine bay look for vacuum leaks (anywhere you find it pulling air into the engine)
3.Clean the tb's and intake filters
4. change out your spark plugs

Sorry if I seem like I'm repeating the same thing that's been said but I would do that order of maintenance before I started really slamming money into the problem.

It's roughly every month, but average 6000kms a month. this month will be over 12,000...

I had after market clutch, the problem was the CSC sucks, if this one goes i'll be doing a aftermarket one, the problem is time to ship it to Canada, etc. ECU was under warranty, it was about 6 months after I got the car. it did however take a month to get the part in...which sucked.

I had to take out the Stillen Flywheel and ACT clutch, it was the cause of the CSC going to often, too much spring pressure for it, as mentioned above I can't have the car off the road long so ordering one in is tricky, but if I don't sell the clutch and flywheel and the CSC goes again i'll wait and get the CSC from Z1. so far I've paid once for the CSC to get done, the dealership has paid twice...so it's not been to bad other then i'm always away when it happens.

OP, clean your throttle bodies.

^ Tried this but still getting issues. Maybe OP will have better luck.

It may be your injectors. Was looking at other causes from the other thread.

See you on Saturday :hello:

I am going to be doing this DIY hose delete as well and could do your car, too if interested: http://www.the370z.com/diy-section-d...nt-delete.html

Also, I'll be doing my power steering fluid. I don't think it uses much fluid, so there will probably be plenty to do both cars if yours needs it as well.

Any issues since the filter and MAF cleaning? You're more than welcome to join the TB cleaning party on Saturday. Just text me :tiphat:

That's an interesting delete. I'll have to look into it before committing.

Probably a yes on the PS fluid. Maybe you could help me get the side skirts aligned a bit better with 3m tape? I'll see if I can get a thicker version in town today.

No problem, it's a pretty easy DIY. Just made easier since we're already removing the TBs.

The PSF capacity is 1.125 qt. I think I have 2 qt of Redline fluid, so it'll just depend on how much fluid it takes to do the ranger protocol a few times. At the very least, we can get some clean fluid into the system.

I'll take a look at your side skirts for sure, but I can't promise anything. Fitment concerns are the primary reason I haven't done any mods to the exterior body. It's kind of annoying when people post that a part has perfect fitment, but then you can clearly tell the gaps aren't within OEM specs :shakes head:

Unless you plan on moving to Yankeeland soon, I'd go ahead and do it while the TBs are out of the way. Only needed if you drive in temperatures well below freezing and don't do much good once the engine bay warms up (unless you're driving in -40 weather). For where you live, just unnecessary heat on the TBs.

Haven't had any issues since. However, I did notice the car kind of sputtered for a split second after start-up earlier this week. I think I'll go ahead and join you guys to clean the TB. It had kind of been lingering on my mind to get it done. I'll text you in the AM.
