Hello All. Hopefully can answer a question for me.
I have a 96 z and it seems to be hesating a little .
I put it in the shop and they replaced the opit spark but it still does the same thing. The car has 51,000 miles. When should i cange the spark plugs? the owners manual says not until 100,000
Also how about the wires. I changed thefuel filter in the 30,000 range. Thanks for any advice.

 

Bummer to spend that money. But anyways, a lot of people have these "hesitation" problems. For now try some cheap dry gas or fuel system treatment which has Isopropyl alchohol in it. It's winter season and cars are more prone to getting condensation/ water in the fuel right now.
