Ok, I am moving up in the world!
many years of Volvo shade tree wrenching...240s...740s...940s...850T...now v70GLT

Pick her up for $900 and runs well. 190k miles.

Got her with CEL on and scanned for cylinder mis-fires. P0300 code series.

I cleaned the rotor tip and dizzy cap terminals...which were bad.
Swapped out with known good coil.
New plugs.

After sitting for a while, still has long crank cold start...will eventually kick over.

After this initial start and running, it will re-start right up and run sweet.

Next obvious things to do are change fuel filter and go thru all vacuum lines.

All those lines to turbo are old and will get changed.

I will need to check fuel pressure (need to tap the fuel-rail line with fitting)
Is this a special fitting or regular bike valve fitting? What is spec pressure?

If the pressure spec's out, should I focus on fuel press regulator? This year is different from 95 850....so cannot swap out. No vac line to pull off and smell for gas.

Also I will put new temp sensor off t-stat housing. Or how do you check that per spec? Resistance vs. temp change?



I know you are out there Klaus......you have the same model

What is nice is the 95 850T has a lot of same parts, so I can swap stuff

Thanks
