Info:
so my issue is I have a bouncing idle during the day and it will stall the car when at a light or between shifts. at night it will usually idle perfectly but sometimes it acts up at night as well.

issue started when i swapped to a victor x im

sensors and manifold worked perfect on the previous owners car (buddy of mine)

only cel I have is o2 sensor

when I unplug the IACV it dies

blows smoke in vtec

engine has like 10,000 miles since full rebuild

engine bogs until 3500 rpm almost like its not getting fuel

stuff i have done:
tb has been cleaned
IACV has been cleaned
valves have been adjusted
timing is right
idle screw has been adjusted
distributor replaced
no vac leaks
spark plugs have been checked
FITV is deleted
coolant is bled
grounds are all good


any ideas before I start throwing more money at it?

my thoughts are replace:
tb/tps
fuel pump
injectors
o2 sensor

 

Stock P28.
Why?
Running a SOHC ECU on a DOHC.
Why?
Many mods with no tune?
Why?

Stock P28-mistake.
Major mods done to a DOHC engine that require a stock SOHC (wrong) ECU to compensate for increased air and fuel without benefit of a chipped or tuned ECU to run them properly will cause your issues. You cannot just slap these parts on and expect to make power. In fact, the opposite can and does occur. Lousy running car.

The only free thing you could do, that I can think of, is check the timing and check adjustments on the TPS.

 

thanks. s300 is coming soon. ill wait till then

 

so..
