Car wont rev past 3000 Help.
 

So I finished my setup and went down the road. Ran nice 10 minutes into it it wont rev past 3000 rpm..I have a 94 civic dx with a rhb5 turbo...I hooked up vacum and boost gaiges. It has a Airfuel gauge and 450s with a vafc. It is a non vtec..I have the wide throttle and narrow throtle set at 35. the air fuel gauge reads rich at idle and it is blowing soome smoke even though it never did before the turbo...The boost gauge reads 8 psi of boost..and like -2 at idle. The vacume reads like 8-10 at idle and 0 when I rev it. I dont know what is wrong. Also my BOV doesnt blow off...Please help me

Well, it sounds like you have a vac leak. You should be getting around -20 at idle. If your BOV isn't working, that's probably your leak. Check your connections.

could be vac leak but I doubt it...
It's limp mode I guess

"..I have the wide throttle and narrow throtle set at 35"

I think that's your problem...set it at -35% not 35%

I do have it at -35 sorry I just mistyped.

seems like you have more than one prob there....but you're saying that when you go wot it won't go past 3k? Are you using a missing link or check valves?

Re: Car wont rev past 3000 Help.
 

No I am not using missing links or check valves. Should I be? I thought with the "hack" you didnt have to. As for what code I dont know yet. It is weird because it ran perfect for like 10 minutes then started acting up.

Re: Car wont rev past 3000 Help.
 

You're right, no check valves with the hack.

Pull those codes. There is your answer. ;)
