Rough running !!!! Car now running a hell of a lot better !

Postby Dave M » Fri Jul 13, 2018 9:53 pm

I posted on the forum last month regarding my D’s engine - since picking it up from Dublin earlier in the year it’s always ran rough - coughing - spluttering - couldn’t set the mixture - my old Skool Volvo guy changed the injectors - seals - rota arm - dizzy cap and plugs - ( 2 plugs were pretty sooted up ) - so car was running better but still not right - especially when cold - Volvo guy was struggling so I bought a reprint manual and dropped it off for a bit of bed time reading over the weekend - he called me to say he believed the thermotime switch needed replacing - so £50 lighter had Arran send it straight to him - couple of days later he calls me to say “ all done “ so all mixture all sorted too and not a huge bill either £130 - went to pick it up and now runs far far better - and no stink of petrol either - so maybe the switch was stuck so giving constant extra fuel even when cold - anyone else had problems with this switch ?
Only thing he didn’t change was fuel filter so any advice on the do’s and dont’s ( bleeding ) etc - if the air filter was the original I would have thought the fuel filter could be too
Also removing the seats - is it just the 4 nuts underneath the car and that’s it ( surely not ) not got no ramp so I’ve had a quick look and already given them a blast of WD40 - any seat belt sensors - I’ve had a quick feel under the passenger seat and sure I felt a couple of wires hanging there ?

The seats are just 4 bolts, I think the seat belt sensor is in the driver side belt buckle and you dont have to touch that to remove the seats. As far as I remember there are no electrical wires going to the seats.

So driver seat out - and cushion reinforced with cable ties and some thick rubber washers and a made a new rear seat panel as the other one was in half and hanging off - but before I put the seat back, where does this cable from the buckle go ? ( note the foil insulation pieces that are fitted under all the carpets and even behind the roof panels ( is it really that cold in New York ?

Those foil pieces are more probably sound deading material

Not sure where that wire connects to, somewhere under the center housing tunnel I think

Look under the carpet towards the rear of the centre console and back board. There should be a multi plug that wire connects to. It's for the seat belt warning buzzer.

Wouldn’t have thought so as it has a non standard straight through de cat red neck exhaust - which is very loud - but there again the PO may have fitted it to reduce noise from it I suppose
