p0420 & p0430 JTS
Hoping someone can help.
Over the weekend I started to give my newly acquired 156 JTS Sele a little service. I changed:
Thermostat (hadn't been getting up to temperature)
Installed cruise control stick.
Didn't have time to do the oil change.
On my way to work this morning i got the dreaded BEEP BEEP BEEP after about 15 minutes of driving...
Anyway. I've read the codes and they are p0420 and p0430. This is strange as these seem to be emissions related but I haven't touched the exhaust or lamba area...
Anyone got any idea where to start. I've read somewhere else that its a case of over-fuelling, but not sure how that could be.
Any advice appreciated.
EDIT - Forgot to mention i broke the clip which attached the air flexi to the ridged plastic inlet tube. Is this of consequence? Seems to fit quite snugly anyway...
Also the wiring on top of the injectors in pretty bad shape...
