It is about time for a tune up on my car. My 1998 has just over 85,000 miles and I have noticed a decrease in mileage. What sorts of things do you do for a tune up? I am thinking changing out the plugs, maybe the wires too. What spark plugs should I use? I am not looking for some super expensive ones, just something that will fire off when I need them to .

You wont gain any power from plugs or plug wires (although you could lose power and mileage going with the wrong plugs). Any plugwire set will do, I'd recommend either NGK or Champion sparkplugs... I had bad luck with autolites. Stick with plain jane copper plugs, they are the best for neons. If you neon is a DOHC you might want to check the TB and intake manifold for sludge... Its a common problem caused by the PCV valve leaking oil into the intake and mixing with carbon from the EGR.

I would also recommend changing the timing belt and belt tensioner soon if you havent already.

Might want to consider checking out your upper 02 sensor also. It can kill your mileage. Also cleaning the injectors could help, do this before changing the plugs so it dont blow junk all over your new ones. Dont forget to replace the air filter also.

Thanks for the tips so far. One thing I forgot to ask was if our cars have a gas filter. I looked in the books at Wally World, and the fram listing was blank under gas/fuel filters.

My car is a plain jane, SOHC, no power options, more power is not what I am in for, just an efficient puddle-jumper

I drive my truck when I want power. And smoke

Make sure you change the time belt or you wont be jumping any puddles with that Neon. Stick with the regular cheap copper Champion plugs. The time belt is a pain to do but it's worth it considering if it breaks you can count on it being down a while if you even fix it. Most people sell em for a few hundred bucks when the belt breaks and bends the valves. The wosrt part is most people just throw on another belt and bend them some more b4 they realize they realy screwed it up in side. Looks like it was all coverd by the other guys, just thought id let you know how important the time belt is on these cars. Alot of them bust around 100K too. Later!

Mopar changed the fuel system setup midway through the 1997 model year. 95-96 had external fuel filters, 98 and up had internal fuel filters integrated into the fuel pump assembly inside the fuel tank. 97's had either or depending on when and where it was manufactured. Fuel injectors also got changed in '97.

I was just tooling around under the hood, checking fluids, pulled the boot off the spark plug, was shocked to see how deep the plugs are. Any tricks to getting them out?? I gotta see if there is a socket skinny enough to get down in there. Any special torque to tighten them? The O2 sensor, how to clean, and the timing belt, how to change?

Any threads you guys can direct me to would be great.

No special tools needed to remove the plugs. An extention and a regular plug socket will work just fine. As far as how to torque them. Just make them hand tight and then give them a 1/4 turn until they are nice and snug. You dont want to torque them in really tight but not loose enough to vibrate out.

If you plan to work on it yourself get a Manual and use it!! In order to change that belt you must remove some stuff includeing a motor mount. Hard to explain all. Get the Haynes or Chilton manual its a life saver! You dont clean an 02 sensor you must replace it. However the IAC can be cleaned. (idle air control) it's on the TB.
