EFi disaster!

[Alastair]

Hey all, need some help please!!!

The rally car is poorly, let a friend borrow my wide band, and now he has wired it back in the car won't idle below 4k, literally with the throttle closed, revs clean from there but I am properly confused.

Spec is bbpt EFi, with r19 ecu and all the Renault sensors....

Any ideas???

Sounds like he has upset some wiring or a sensor? Any pipes hanging off inlet causing an air leak?

Unplug the wideband, if it runs then there is a
Prob with the wiring there... Does it run closed loop with an ecu or just a gauge to monitor with?
