Tune up question

How often do you get one done? Only after a certain number of miles? Certain period of time? Or a combination of both?

I did mine at 40,000 becaues that is what it had when I got it. So I wanted to start with a clean slate. I didn't know what the PO had done to it. I also changed all the fluids. But I am with wwch99tj I would do it at 50,000.

How often a tuneup needs to be done is more about how new your engine is (whether or not it has a distributor) and what technology spark plugs are installed.

A 2000 and newer 4.0L engine with platinum or iridium tipped plugs can go over 100K miles before the plugs need to be changed. A '99 4.0L (which has a distributor) with conventional spark plugs probably shouldn't go past 40K miles without at least replacing the plugs.

So generally speaking, older distributor-equipped engines with conventional spark plugs need tuneups far more often than modern distributorless engines that tend to run platinum or iridium plugs do.

My first car, a '57 Chevy with the 283 V8 engine, required new plugs, points, condenser, distributor cap, and rotor about every 10K miles. My '04 TJ barely needs spark plugs every 100K miles.

Haven't replaced any fluids or anything for 30,000 miles and still going strong!

My grandma has a 97-98 toyota 4runner, hasnt changed oil in 4 years... Drives it every day, has over 180,000 miles on it. She doesnt want to change the oil because if it breaks down, my grandpa will let her get a new car So she's been trying to kill it with no luck.. GO GRANDMA

What does the 99 model with 2.5L engine come with? I see that it has a distributor but did they still use points as late as 99? I remember what a nightmare setting the gap was. Don't wanna touch it.

Ha, no. Ignition points went away in the mid 70's for the most part.

Don't still have that '57 Heavy Chevy, do you? I bet you wish you did, if you don't!!

My '65 Olds Cutlass F-85 with a 330ci, 315hp, can MAYBE get 10,000 miles out of a set of plugs, but usually start noticing it's not running PERFECT at about 5,000.

Yes, I still have the above vehicle too!! Just rolled over to 74,000 ORIGINAL miles last summer. I've had car since 1983!

My '01 TJ has 115,000 miles on it. Had 93,000 on it when I got it, I think. I knew the person who owned it originally. They had changed the plugs at about 75,000 before trading Jeep in on another vehicle. I then bought Jeep from car lot for EXACT amount they gave my friend for trade in. It worked out pretty decent as I was with him when we/they did the dealing, so dealer didn't want to give friend to much for trade in, but didn't want to lose out on to much either for selling it to me for exactly what they gave friend.

Been thinking of looking at plugs just to check them. Personally, I'm not hip on the idea of a set of plugs going 100,000 miles! Plugs don't cost that much and with price of gas, this is a relatively easy way to keep mpg's up there.
