ecu cutting back fuel?

akintg95

Nah it still is getting fuel

bbsIx

yea i kno. when conditions arent met for vtec, the ECU cuts back fuel at a certain but low rpm to stop you from damaging shit, its usually that your low on oil.

i agree with checking oil level.....

akintg95

oil is good i check it everyday to make sure huh this is just a brain buster though i cant figure it out

Is this a converted VTEC car?

akintg95

yeah but it has a gsr obd2 wiring harness and for some reason the vtec wires are cut at least 3 times and spiced back together

If the splices are crap (which is often the case when people work on their own cars) the solenoid might not get getting enough current to keep it engaged continuously. If you do a continuity check, it will look perfectly fine because the multimeter current is very low. Operationally though, it might not be able to drive the coil into saturation.

I agree with Chris above..... why not rerun the wires instead?
