i just did swap in my 87 turbo II. i replaced it with j-spec engine. i got it started but it runs very rough.i think it is running on one rotor. compression is good. i dont think that rear rotor is getting fuel. (this was original problem with my old motor) > after i get it hot it is very hard to get it started again. plugs get soaked with fuel( only front rotor though-rear rotor plugs are ok). also it revs really slow and when it gets to higher rpm starts to pop. it runs rich too. cant run it in garage thats how bad it is. i'm stuck guys i dont know where to turn anymore. i dont know if is any selenoids/sensors to cut the fuel to the rear rotor or what. anyone have any ideas please let me know.
thank you very much (i removed the air pump and pluged the acv. all the vacum lines are pluged in and i gotta block-off plate for acv) |
Sounds like your injector harness is not properly connected and the rear injector is not firing. Sometimes the metal clip inside the injector cuppling backs up and no contact with the injector is made.

Hopefully it's not a bad injector. I had a set of those and mine barely ran and wouldn't rev at all. Swapped the injectors and it was fine.
If the rotor is flooded... try pulling the spark plug wire away from the plug a good amount (do this while it is running)... or someone cranking the engine. This will cause a flooded plug to fire. I had to do this also to get my car running after it sat for some time. |
did you reuse your wiring harness?

what i did discover today that when i sprayed some carb clean into the vacum line that is located on the plenum(that line leads to the rear rotor intake chamber) engine will run fine. so for sure i'm not getting any fuel to the back rotor. so when i spray carb clean i'm feeding it with fuel and the engine is running good.
I had to use my old injectors because my wiring harnes injector plugs are differnt from the jspec injector now i have 4 jspec injectors and i found some conectors that would fit perfect. can i just cut my old conectors and solder the ones for the j-spec injectors so that i will be able to use them???? |
and one more thing ,can you guys tell me when secondary injectors should kick in.
what rpm range. |
I don't see why not.. 3800rpms the secondaries come on..

mike they dont have the solenoids on the acv, the aws valve or egr, but i think he might have a bad harness mike |
