Adjusting Idle Speed and other questions...
 

How do I adjust the idle speed on an 87 n/a? Mine's running a little low, around 700. Unfortunately, I don't have a manual to look at right now. Is is fairly straightforward?

Also, to complete my self tune-up, where is and how do I change the fuel filter? If anyone knows of a website that has instructions or whatever, lemme know.

Thanx!

Fuel filter is on the firewall on the driver's side. The manual recommends doing it from under the car. The filter is held by a bracket, it's easier to remove it then try to fit the filter on the car.

Idle adjustment is pretty easy. To do it the right way:

1. Run vehicle and let it warm up to operating temp. Turn off vehicle.

2. Locate the initial set plug. It is a green plug on the drivers side by the primary ignition coil. There are two plugs there the one with six or so connections is for ECU code checking. HTe one with two connections is the initial set plug that you are looking for. Attatch a jumper wire to bridge the terminals of the initial set plug. (this puts the computer into a special mode so that things like the BAC and other things arent operating)

3. Start car

4. To adjust the idle, locate the idle set screw located on the top of the intake manifold. Some people have a plastic cover over this screw, if so, take it off. Adjust idle to your liking (stock: 750 rpms)

5. Turn off car, remove jumper wire, and you are set!

Thanks guys!
