Rough idle/no rev problem

Hello tada,

did you get my wiring plan for the car? Did you check the wiring loom?

3 broken injectors at once? Hm, implausible.

Got the diagram, thanks. I ohmed the harness out and found no problems. I was hoping to find a short to ground. I used a noid light and saw the harness working correctly. But I can't get my meter leads into the actual fuel injectors themselves because the air box is in the way. If one of the three injectors is shorting to ground internally, it could cause a failure on all three.

That is correct. OK, pull them an check them.

Maybe they can also be checked if you measure the resistance of the fuel injectors at the ecu - if you diconnect the wiring plug. I don't know the resistance value that should be measured there, but they should be the same as on the other bank.
