Hi all and a very early merry xmas..
My P38 3.9 1995 failed on just emissions for mot. I say just as have been getting scare stories of possible cats needing replacing. Paid to get it hooked up for fault readings came back with:
PO 116 Engine temp switch failing
PO 340 Camshaft sensor signal error fault.
CO is too high on fast idle - 0.718% instead of <=.300%
HC passed at 36 ppm
lambda failed at 1.045 just over limit of 1.030
Have been reading through past posts ranging from new lambdas to some interestingly sounding emissions pass additive thingy. Had 2 new lambdas replaced 3 months ago along with fuel pump, just lately been smoking out back whitey/grey and smells of carbon. Been running smooth until got it back from testing station where it now feels a bit stuttery, like a small constant misfire which seems to clear slightly if i get to go higher up the rev range.
It is lpg also but has not been used for months..
Any new ideas/experiences most welcome, especially if involves a quick job as need to go Frenchay Hospital on Thursday and police would prefer it if i had a valid mot certificate..
Thanking vous in advance
