Hi Guys,

Working on my 91 300D, hoping to get your thought on my strange idle problem.


On cold start after about 1min or so of a decently normal idle it will suddenly sound worse and worse, like a cylinder is not running right. Once that happens all kinds of white smoke comes out the tail pipe.

I took a video so you could see.

I have new injector nozzles rebuilt by greazzer and have replaced the delivery valve seals already.

What do you guys think?
