Asked by for the 1999 Nissan Quest
You stated "I have changed changed up to four" ignition coils right? Then in the distributor is where the coil is, on a 99 Quest 3.3. Have that whole assembly replaced with all componets already in it. Google 99 Nissan 3.3 distributor and see what it is! Who changed those coils?
