low idle and sluggish acceleration

Aug 23, 2007 Last reply: 18 years ago 1 Replies

My 1984 300zx turbo has started having a low idle and is sluggish with acceleration. It also does not seem to gain full acceleration or speed. Any ideas or suggestions?



Thanks!


You can start out by finding out if all of you pistons are fireing. The way to do this is unplug one spark plug at a time, while your doing this look for a drop in idle. It the plug is fireing you should see a drop in idle after unpluging the wire from the sparkplug. If no drop then that may be your bad piston.
