Sudden lost of power!!!
HI Gentlemen!!
My Greddy kit has been on my car for 7 months now, but recently there is a glitch with daily driving issue. ( ALL Mods are listed in signature)
- Suddenly the car loses power, it feels as its pouring way too much fuel. I couldn't even get up the hill with full thottle.
- Usually it starts acting like this, once the car has been heated up.
- Disconnect than connect the battery helps for a moment or so.
What could be causing this problem?
- No Sparks? Coil?
- AFM?
- O2 sensor?
- other?
HELP PLEASE!

so it sounds like the problem is intermittent correct? If so then I wouldn't think it to be a vacuum leak. Happens when the car is warmed up? I dont know why it would be like that. Im going to have to second taking the EMB out, is it possible that the AFPR is sticking?

Having a Fuel Pressure gauage and WB would be really handy now! haha
Its so hard to track down the problem since its not always happening.
Here are where it could go wrong:
- EMB
- AFM
- 02 sensor
- AFPR
- Fuel Pump
- Coil pack/spark
- ECU
dammit!

to disable the vortech, remove vacuum line...
that is , when funktioning properly...
you can check the vortech by removing it...the fuel line to the vortech should have no pressure (remove fuel filler cap first)
you should be able to blow airtrough the fuel lines witthout too much problem...
