Do yourself a favor and make the necessary repairs to the OMP wiring. The positioning switch, and power of the OMP are very important. Put four new bur9eqp plugs in. Make sure you hook the plug wires up to your coil configuration. Use the commander to go to the sensor check page. You can then check that your tps is reading smoothly from closed throttle to full open. You can also see if your map sensor is reading / fluctuating with pressure - vacuum. This screen is very helpful for quick troubleshooting. After that, start the car, let it come to 80c and use the commander to view what P/N rows you’re idling in then lean out that cell and the cells around that until your idle isn’t fatter than 12.6.. I do not know anything about your setup ( porting, injectors, ect ) so I can not tell you what afr to target. My suggestion would be high 12s with the idle stabilized. If you lean those cells out to much all that will happen is it will surge. After you’ve done all that you can reconvene. To me, it just sounds like you’re fouling a plug due to the super fat idle and it cleans up when under load. Sound like you need a tune.

yea i got new plugs on the way and oil injectors the wiring is fine but the check valve failed on my injectors so it was spraying 2 stroke oil in the vacuum lines, i forgot to mention but when it was acting up this last time it was really lean

 

If you have a datalogit, xb340 or master unit you really need to take a log when it’s acting up so you can pinpoint it.

Yea a data logger is on the list
