has anyone heard of this? i put a jdm single cam in my girlfriends 92 hatch and it starts up and idles about 1500rpm but when you step on the gas the car dies. i think the fit valve may be bad but i dont think that it would cause the car to die when i step on the gas. any help would be much appreciated.

 

are you sure you got the cam timing correct

 

double check on the firing order and the timing like PONTIAC says.

 

ill check it again but i was thinkin since it dies when you open the throttle that it would be maybe something with the injectors

 

If your timing is correct it is defenatly a fuel problem. I would start with the map sensor. Perhaps you got the map sensor & tps sensor plugs mixed up. Are you getting a check engine light?

 

yes i am getting a check engine light. i found a vacuum leak yesterday from the throttle body gasket so im going to change that today and see what happens. im not sure but there might have been a leak coming from the fuel rail/ injector area but ill test the vacuum again and see what happens and let you guys know

 

the shitty thing is.. i bought this thing from hmotorsonline and ive replaced the iacv and now im changin gaskets.. i just hope this is it

 

make sure the radiator is completely full also, i was having problems with mine idleing high and dying (engine revved but died afterwards), filled the res. up and it immediately started running correctly. hope i helped!

 

almost sounds like throttle position or map sensor is bad, or hooked up in the wrong place.
