94 850 Turbo barely runs

Post by skloon »

So this am jumped in the car that I had driven Saturday for 100 or so KM without a hiccup and it started- sort-of idled at 500 rpm wouldn't respond to the throttle then it stalled, I was able to restart it a couple of times for a second or two until I grabbed the wife's V70 and headed off to work. I checked that I hadn't blown off an intake hose, I lean towards the MAF or fuel injection relay

Okay got home swapped fuel injector relay and it didn't start- unplugged MAF and it started blew a ton of smoke- re plugged in MAF checked codes and it runs swapped old relay and again it didn't start so I guess it was the relay

Yeah really weird- lucky I had two spare relays- the one I removed was date coded nov 1993 just before the car was assembled so I think it did it's job well
