idle problems !!!
« on: September 25, 2006, 10:20:36 »
Hello group,

I Have a 1966 230sl automatic and it drives great for an hour or so then when slowing down at light or off ramp on highway it begins to sputter and stall when at idle (in fouth or neutral). Any help would be great. ( Just got car 3 months ago). Thanks

Fuel, fuel, fuel.

You can use the Search tool to get more details on these points:
- First, find the Fuel Tank Tour thread and read that.
- Remove fuel guage sender from fuel tank (through trunk floor) and inspect fuel tank for rust.  Drain tank and replace in-tank filter if suspected of being clogged.
- Remove inlet to electric fuel pump and see if you have a screen clogged (see recent fuel pump maintenance thread).
- Remove main fuel filter in engine bay and replace.  Sloppy job, have rags handy!
- Once all fuel filters are checked and clear, test fuel flow rate of electric pump at the return line to the tank.  If rate is low, you have a weak pump or a blockage.
- If this all checks out OK, then come back for more suggestions.
