Ok I have had a persistant and annoying low vacuum condition that I cannot figure out. While the vacuum is low the car has zero power and literally cannot pull out into traffic.
Its not a leak anywhere in the intake system. I hooked it up to a smoke machine and pumped in smoke for several minutes and no smoke leaked out.
I have checked just about every vac line in the car. Sprayed carb fluid everywhere blah blah.
Today just for fun I took off the entire intercooler setup and discovered my check valve on my DO WI kit was NOT working. A few oz of water came out of the charge pipe.
I was happy and figured that was the problem so I threw the stock plastic intake system on. This made pretty much zero difference. What is strange is sometimes it will idle with a normal vac of 19/20 but then it will lower to 14. If you rev the car and let it go back to idle it will go back to 19/20 and then sometimes the vac will go lower.
When the car is cold it runs like total ****. Zero power, you can almost out walk it while its floored. Sometimes giving the car some gas will make the revs go LOWER instead of higher ha!
I am going nuts over this while situation. Anybody have any advice? I tried on miata.net a few months ago and that when nowhere with everybody telling me to check my intercooler pipes when I told them several times they have been checked.
It may be the crack nose again, but I don't want to take off that crank bolt again. There is a healthy amount of loctite down there and I am sure it will be a massive bitch to take off again. It sucks that there is no good method to tell if the alignment has slipped due to the crank nose getting yoked out.
Ok here is my car's setup. I know its a greddy kit not DIY, but I consider the POS kit to be DIY anyways.
1990 miata (loctite fixed) Checked to see if the crank nose is fucked (again), I checked to the best of my ability and it's fine. Also the TB has not slipped a tooth or anything.
Greddy with Starion IC (disconnected) @ 6psi
TurboXS POS BOV (Disconnected)
Devils Own WI (Leaking check valve. Compleatly Disconnected.)
Thanks guys for any ideas.
