Hello,
I've had my '98 LS400 for 5 years now (love it).
It seems when it's cold out and I first start driving the car will have a strong shake - it's not usually consistant and sometimes doesn't even happen (usually it does at least a little shake) -- once the car has been driven for a few minutes the "shaking" goes away.
I kinda feel like it's a throttle issue but would love to have suggestions in specific.
This issue started last winter on cold days but once the spring came and weather was warmer the problem went away........I didn't have one single issue for the entire spring/summer season. Now that it's getting cold - the issue came back on cold days. Thing is I can't always duplicate the problem.
Also, the car doesn't seem to idle any higher or lower than normal (that I can tell) and otherwise drives perfectly (no slipping of gears or any other issues).
Thanks,
