I have searched the archived posts on previous problems to no avail.
The problem that I am having is with my b18c swapped rex, I had run the car for roughly 500 miles with no issues like I am having rite now. The car will start usually after 4-5 cranks and go into fast idle around 1600 then settle down to 750 where it is supposed to be after warmed up. The problem is that if I give it a shot of gas after the car is warmed up the car will come right back down to 0 on the tach and stall out. I'll start it back up and everything idles fine until I give it another shot of gas then the problem will persist, also the car will stall everytime I push in the clutch and the revs drop to where they should hold at 750 but don't and just quits. With the car running and warmed up I unplug the IACV and the idle just sits at 800-900 or so but will not stall when you rev the engine and it comes back down to idle. With the iac unplugged the rpms seem to cut in and out around 3000 when held steadily with the gas but is fine above that rpm. I have replaced the main relay just last summer and the fuel filter has just been changed. Fuel pressure is a constant 36 psi at the fuel rail at idle. The only thing that I was thinking the problem might be is the throttlebody that I had bored to 64 mm by a local machine shop wich they also installed a new throttle plate, I havent touched anything on the throttle body since I got it back.


For the ignition system the car is running a MSD digital 6al ignition with a blaster hvc coil.

The fuel injectors are MSD 358 cc injectors

I'm running a pr3 ecu with a hondata stage 2 system that has been given a basemap and fuel has been trimmed from the bigger injectors.

The engine is runing 11.8:1 comp and skunk 2 stg 2 cams and full valvetrain and a Act prolite flywheel.

All opinions are welsome as this is really getting frustrating and I want to get this figured out.

 

evening bump, let me know what you think guys.
