just put in new Venom 550CC injectors on my 87 RX7 Turbo II with N332 ECU. I have a N318 MAF. Now the car idles and 1800rpm i only have 6PSI of boost and 8PSI of Vacuum. Spark Plugs are new and matched. Sometimes its also hard to start takes a while to crank and start. Any help would be appreciated. I did check the timing last night also. Also i believe my car was converted from NA to Turbo. Once i lookd at the harness everything is chopped up and the injectors plugs were also chopped up and redone.

 

did the thing idle at 750 like a champ, all day long, hot or cold - BEFORE you did this?

 

Vacuum leak?

As in the grommets at the bottom of the fuel injectors? Yes!

 

i seated the injectors in properly i dont kno where the leak would be... I have a big vacuum line on the right side of the throttle boddy on the bottom thats not connected to anything. Does anyone have a vacuum diagram for this car? before i did the injectors it would idle at 1200rpm still a bit high but not as high as now. Any help is appreciated

 

try spraying some brake cleaner or something in the engine bay if the motor revs up you find your vaccum leak

 

where should i spray towards the injectors or the throttle body?

 

where ever you think its leaking

 

alright i adjusted the car now it idles at 1100rpm i adjusted the screw by the throttle body. But what about the 6psi vacuum??? but when it first starts it idles at 700 then once i step on the gas its 1100rpms.. Also the fan is constantly on? why is that?

 

The fan is on because a fuse is out OR the auxillary fan temperature sensor output wire is OFF. Temp switch is on the thermostat housing.

I've never seen a vacuum line on the right side of the throttle body.

For the high rpms, I'd check that the fast idle cam has departed the roll pin. See the FSM and the Fuel section for the rigging of the waterthermowax/fast idle cam/roll pin.

Of the four metal nipples on the back of the throttle body, the top one is capped, the next is for the fuel injector air bleed, the third down is for the oil injector bleed air, and the last nipple, the only real vacuum nipple, is for the double throttle diaphram. See the FSM for what a double throttle diaphram does in life.
