95 LHS Spark plug problem?
I have a 95 LHS with the 3.5 and am having a problem with plug wear on the right side. The electrodes are wearing quickly. And on the left,there is more signs of detonation, speckling. Is this the knock sensor, are there 2 sensors on this engine? Is there a test for the sensors?
Thank You

There is only one sensor and yes there is a test you can do but you need the DRBII. and your "speckling" is probably from a leaking injector or your ignitor pack is messed up. Pull the plug wires at the pack and see if you are getting secondary spark tracks. If so change both of them

rick has a good point there also I would say to check for a intake manifold leak. This is very common on those vehicles. Just do a water test on the manifold to find the leak if there is one.
