My 2004 BA Falcon MK2 ute shakes and shudders while at idle. It comes and goes intermittently when underway, but it's worse under braking. This has been happening for the last few months and is progressively getting worse. I have had it serviced without any success. Any suggestions?
I suspect you have a vacuum leak, probably caused by a cracked or split vacuum fitting on the brake booster.
