Title: Suzuki wagon R/ Vauxhall agila. F/Code
Post by: The Red Baron on 05 December 2015, 21:00:33

As above. 2006 model. 1.3l
I have code PO170 come up.
Starts fine, pull away and it coughs and splutters. Ok when warm.
Does have a strange surge at light throttle.
Also has silly k&n filter on it. Not by me.
Any idea's peeps.
:-)
Jon.

Assuming the codes are similar to the facelift Omega

P0170 Fuel trim malfunction (Bank 1)

(or in other words the MAF is shagged due to oil contamination from the K&N) ::)

Unplugging the MAF should make it drivable & confirm the diagnosis........

Assuming that the diagnosis is correct then the engine will run in limp mode with the MAF unplugged.

If you fit a new MAF then the ECU will try to run with the current (incorrect) fuel trims - do you have a code reader with the ability to reset the fuel trims?
