Rough Idle on 300 Diesel
« on: 10 June 2007, 04:54 PM »
My engine idles VERY rough and even causes the body to rock at red lights in and out of gear.  What areas should I look at to correct this?  I have bought some engine shocks (2) to install but want to have a list of items to check first before installing them.  I would hate to put them in and still have the problem.

I am the proud owner of a 1980 300 SD Turbo Diesel W116.  I found the vehicle in Palm Desert California in 2006.  I have gradually restored the vehicle mechanically and appearance wise back to original OEM.
