Hi, i have done a search but could not fine anything...I have bought 3 check valves to bypass the map sensor from aquarium services one way check valve with spring and ball,after installing to vaccum line running from the map sensor to the throttle,the car idle and bogges down then dies i would like some help i have switch around the check valve to make sure it's on right but cannot fine out what wrong please help or provide a pic to see how you guy's have done it.

 

If you really really really must do with the check valve thing, I would say get a missing link.

I highly suggest you to get it tuned with Uberdata or Crome, it's much cheaper. Your car will thank you later.

 

Make sure it's tight on the map sensor, if it's not you car will bog down. Then get a missing link

 

I live in canada do know anyone who can chip ecu and program.but thanks until then need to use check valve...so i have installed it correctly maybe not sealed properly is that the case.
