Cold starting is typically ECT sensor or fuel pressure. Does the car start ok when warm? The ECT sensor is critical on these cars. Misha might remind us what is the non-Volvo brand (OEM I think is Vernet? which is not available over here). If the PCV is bad, this will affect the car running. I can't...

U.S market don't have 10v cars. Dtc you have is telling you that fuel mixture is too weak....could be lack of fuel or lack of air. However...when there is LPG system fitted...it's harder to diagnose the problem because there is too much splicing into original wiring loom which will corrupt proper si...

I only ever see these wires going into harnesses, never dug into these. But seems like they use a common sensor ground. Looked up ecu pin A18, says "Signal ground sensor (measure with neg. batt.)" have you measured resistance - sensor wire ground pin on sensor side to ground? - sensor wire...

I think that is the best pic I have, maybe someone else has some more info on the connectors. Note its from a me4.4, but shouldn't matter for numbering.

Ok, here is my final and definitive post on Bougicord spark plug leads for 850 Volvos. As mentioned previously my Australian delivered / built ( yes they built them in Victoria AUSTRALIA at the Centre Rd Nissan Factory ) is fitted with Bougicord Series C-1 spark plug and HT lead.
