hello i have a 94 honda civic ex d16z6 with simple bolt-ons, i have a very low idle that causes the whole car to shake about 300rpm. ive tryed turning up the idle by the air/fuel idle screw. i works for about an 1/2 hour and then drops to 300rpm again. i found one thing that temporarly works is turning on my heater full blast and the idle goes up to normal. sounds electrical but i don't know were to start. any ideas?

 

bump.... what happend to the tech on honda-tech?

 

The reason no one is responding is because there are literally hundreds of threads exactly like this one about a low/rough idle.

Is it throwing any engine codes?
