Can an ignition coil be weak?
Most ignition coils are long lasting and reliable, but a weak coil you can be the cause of under-hood havoc. You cannot operate a car smoothly without delivering high voltage to the spark plugs to ignite the air-fuel mixture. Most coil failures result from secondary winding defects.
How do you increase ignition coil voltage?
By winding more turns of wire on the secondary coil than on the primary coil, a voltage step-up can be produced. The degree of voltage step-up that can be induced in the ignition coil is generally proportional to the turns ratio.
Where are the coil packs on a Volvo 960?
Remove spark plug access cover. (Black cover on top of engine.) Once you have the black plastic cover off, number the coil packs with a magic marker 1 – 6 front to back so you can correctly replace them. Coil packs are held in with a pair of 10mm bolts (A and B in the illustration.

What should I do if my Volvo 960 engine is failing?
See 960 FAQ file for information on failing engine wiring harnesses. If you have comprssed air blow out the plug cavity before you take the plug out. As an alternative use a vacuum cleaner and brush to clean any “stuff” out of the hole to avoid having it fall into the cylinder. Remove spark plugs.
Where is the VIN number on a Volvo 960?
