Firstv70 - I’ve been through all the vacuum lines, everything looks good. I’d call it a hydraulic problem if it weren’t for the pump running all the time. There is no crack in the foot of hose before the booster, and you can feel strong vacuum when you pull it out of the booster. There is also good ...

I thought of that, I tried blowing into the vacuum line and there is resistance after a second or two, but I know I’m not moving as much air… time to get out the home made smoke machine I made years ago (requires a cigarette in a glass jar, lol

In the last week or so I've done all the fun jobs on my 04 XC70. Throttle Body. Pads and discs on all 4, rear calipers, master cylinder and booster. I haven't worked on my car(s) in years, haven't had the time. I think this has been the most theraputic few days I've had in a while (other than the ...

Hi all - can't believe I haven't been here in 7 years! Doing a full brake job on my old 2004 XC70. Replace pads and rotors up front, everything in the back. All good but the pedal was creeping to to floor, changed the master cylinder, bled over a litre of new fluid through the system (yes, including ...

New update. Changed the injectors today and it started and ran much better, but the idle was high. Noticed that the intake had become disconnected from the airbox ! So it runs well with no air going past the MAF. Took out the new MAF, put the old one back in and it now idles !! The revs drip down ...

UPDATE : replaced the fuel pump, some improvement. Decided to doubt my work so I pulled the Intake and replaced the gasket, and the TB gasket, no change. I put in a new Fuel Pressure regulator and now it starts fine, idles well for about 20 seconds then dies. Once it warms up a bit it only runs for ...

Smoke tested again today to double check, no leaks. Just got the fuel pump, hope to put it in tomorrow. If this doesn't do it...??

Found that whoever last changed the pump didn't replace the whole unit, just the pump. The in-tank hose was clamped below the metal hose, and not properly secured, so i expect half the fuel was not getting to the engine. Unfortunately, the metal lines on the outside of the pump were rusted and one ...

Re the fuel pressure regulator - best test is what? It should just be leak free, i take it...

Put a new (used) coil on today, no change. Checked the ETC and found one lead disconnected, not sure that happened the other day when i was messing around with the vacuum hose on the end of the intake manifold...Anyway, starts and runs better when cold, or after sitting, idles better but only runs ...
