So i have a build d16z6. Ill give the specs

Block-d16z6
Cp 9.0 cr 75.5mm pistons
Eagle rods
ACL bearing

Head-
Comp Cams 59300
Comp Valves
Comp Springs
Comp Retainers

Skunk2 Proseries IM
Walbro Fuel Pump

Everything else is OEM from Honda
Everything has been replaced.

All sensors and harness were used from a perfectly running d16z6 that was just pulled outa the car. After solving a few CELs i finally got the engine to start. I ended up unplugging the purge selenoid and got that car to start. With it plugged in the car would jsut die. I replaced the line bc it looked like it was pinching itself.

After trying to start the car with the rad cap off to bleed the system it just wouldnt keep running. It ran with the engine cold but once it warmed up it died on its own. I put the rad cap back on and it idled on its own. I took it out for a test drive. If i start the engine cold it idles between less then 500 and surges to 1000rpms. then it steadys out at 700 give or take. Once it warms up it dies. If i keep giving it gas and drive the car it runs but once i let off the gas and the rpms drop the car stauls out.

Is this a Fuel problem? or is it a Vaccum leak? Or do i need to raise the idle up?

Any and all help greatly appreciated.

 

i would raise the idle up and make sure you have a working TPS

 

the TPS is wrkin

whats the best way to raise the idle? throttle cable or idle screw?

 

What kind of fuel management you running? Are you using a stock ecu or a chipped ecu? Here is some things you could check out. Check for vac leaks, check fuel pressure, check IACV, check throttle cable, check FITV. Good luck

 

did you bypass any coolant hoses?The cold start valve seems like it's not geeting the correct coolant pressure.I had the same thing happen to me I bled the system and it fixed it.

 

ill bleed it some more

no hoses were bypassd

fuel system is all stock other then the fuel pump
