Anyone?

bump.

I have a stumble which sometimes is followed by a stall immediately after start up. It does it after sitting overnight or after several hours. It NEVER does it on a restart. I never said what my fuel pressure observations were. But, when running it starts out at 51 psi immediately after start up and...

With the engine running I have read that it could be anywhere from 42 to 51 psi, depending on barometric pressure.

Thanks in advance.

I have a code reader, its just that I would prefer to not rely on the computer to set a code. Seems to me that it would be way easier to buy a DVOM and know how to use it than to switch the coils.

Thanks much.

JRL: Are you the same JRL that posts over at XCVOLVO.COM?? IF so,... small world isn't it. Thanks.

I am looking at replacing the plugs with Volvo number 8692071.

Can anyone confirm that these are the correct plugs and tell me what the proper gap is?

Is the a direct Bosch equivalent part number for individual plugs?
