Hey all,
I had my car in the shop 99tl (just turned 100k yesterday) to do the t-belt, h2o pump, all drive hoses and belts, and spark plugs). The old plugs looked great with no oil on the threads but they defintely looked burned and the insulating core had some burn marks as well. Overall, not bad for 100k though.

OK, enough rambling...my Q is are there spark plug wires on the 99 that need to be changed as well. I dont see any but I am not sure what lies beneath :-)

Thanks in advance for your response.

I don't think there are plug wires on that year of car. Each cylinder has it's own secondary ignition coil directly above each spark plug. Not sure about the 99's but that's what the 03's have.

 

yea there arent any just like Tom Blasing said, there are coils on each plug
