i'm running 3 check valves from the throttle and i used T's to do them... i'm just wondering why other people are using them and arn't throwing any cel's off.. or are they?.. i can get away with first and second gear.. but third gear will definetly throw my CEL On...

 

Yeah, I had the same problem. keep adding check valves 'til it goes away. Three is a good start but I needed more. The problem is those @!#$%&* check valves don't flow enough to relieve the pressure. Or buy an electronic MAP limiter from me for $20. Or buy a missing link, even those poop out I hear at about 12 psi (not sure on that number).

 

Oh yeah I forgot to add, you can try small diameter vacuum tubing from the manifold to the check valve tee and large diameter tubing from the tee to the MAP sensor and from the tee to the check valves. You could also try partially restricting the vaccum line from the manifold to the tee with a paper clip or tie wrap or something, and punching a small hole with a hot pin in the line from your tee to the MAP sensor. Good luck.

 

that paper clip thing sounds good for now.. well i already got a missing link coming in now.. thanks

 

are you guys sure that they (checkvalves) are in the right way?
