Volvo v70 GLT, fails and staling in hight acceleration

[djekan]

What brand are the cables and spark plugs?
Nothing really works except Bougicord on these cars.

Spark plugs can be cheap copper BUT MUST be properly gapped for turbo engines.

N/a can get away with larger gap but for turbo engines gap is critical.

Hi,
I'm doesn't know what brand is the cables, but have VOLVO marked on it

The spark plugs are new NGK IGR6A11, but I doesn't make any gap, they are like comes from OEM

Thank you

OE Volvo for turbo engines(set of 5) are platinum...but NGK iridium are also excellent.

Volvo spark plug cables are made by Bougicord...if you look at them...you will see Volvo Bougicord written on them.

I suspect on TPS sensor,fuel pump relay or a hole in intercooler.

You can remove a fuel pump relay and put a jumper wire between terminals to rule out bad fuel pump relay.

OK, I'm suspect on TPS too, I'm waiting for arrive that and one camshaft sensor for chech if it solves.

Fuel pump relay I don't think so, because the V70 have LPG sistem and it fails on both fuels, when I run on LPG the petrol pump is working but return the petrol for tank.

Hi there,
Issue solved, for incredible the problem was the spark plugs, I'm bought iridium spark plugs must be platinum I think, before the stalling problems I've put back the old sparks NGK PFR6B, but not solve so today remove the new ones BKR6EIX and put the gap at 0.6mm (recommend for. LPG system) and no more stalling.

I'm don't understand well the difference of 0,02mm make that big difference


But OK, I'm happy for solve this, may be I will change it to OEM platinum sparks.


Thank you very much for all support.

0.6-0.7mm is proper spark plug gap for turbo engines.
It's for n/a too,but turbo engines are more sensitive to spark plug gap.
