Poor Mz Ruby.
Our 66 Polara 383 4v picked up the shakes. Off idle the engine shakes. Cold , it sounds like a diesel until she clears her head. It's a steady shake too, until I raise the rpm
I checked the choke, idle screws, dwell and idle. Nothing failed or went out of whack, that I can see. the idle isn't fast, nor do I hear air, like a vacuum leak.
Last week I was headed for a cruise across town We put a little gas in her, Same brand, same octane (we hope) but different station.
I noticed a stumble off idle leaving stoplights as we cruised the avenue after parking for little bit.
When I put her in storage Monday night, she sounded awful. Off idle she was chuggin'. No backfires or exhaust pops. Just the shakes.
BTW the shakes disappear at cruising speeds or medium acceleration. They seemed to get better as the car reaches heat sink.
I filled up with premium unleaded at the normal station, and added some gas dry in case the last fill had water in it. I thought the shakes were getting better, but they really aren't.
Fuel doesn't seem to be the issue. Full throttle kick down works fine.
I realize diagnosis by internet can be dicey at times. But what comes to mind? Ignition advance?
Thanks in advance for reading.
