Re: rough idle

For the idle first check that the idle switch is working when the 
throttle spool hits it (check with a meter). Make sure that the 3 
screws on the intake are lightly screwed all the way in. Next make 
sure there is power to the lambda circuit, the most common failure is 
a bad lambda relay. Check all of the inputs to the lambda computer and 
connections to the frequency valve. Gas mileage for the automatic is 
less than for the 5 speed. On my most recent trip to Rhode Island it 
was mostly highway driving and I got about 20 mpg. City driving is 
probably about 16-17. If the idle is still rough you probably will 
wind up replacing the plugs and ignition wires. You might also have a 
dirty injector, If they are all not putting out a good spray and the 
same amount the engine will not run smooth at idle but will get 
smoother as the rpm's increase.
