What would you include with a tune up for replacement parts? I was quoted about $400.00 for the tune up sounds high for plugs, wires, cap&rotor.

Your codes indicate misfires. What was done in the "tune up"? Misfires can be caused by any of several different causes including (but not limited to):
spark plugs
spark plug wires
coil packs
injectors
injector wires

The term "tune up" used to mean, "replace points, condenser, distributor cap and rotor, and plugs". Since most cars no longer have points, condenser, distributor cap and rotor, we need to ask what was done...

distributor cap ? w/ rotor (inside) , also, a tune-up includes the following, : replace spark plugs, plug wires, both the air & fuel filters, an absolute must !!!!!! change motor oil, & oil filter. and one more maintenance issue always over looked, change the TRANSMISSION fluid & filter !!!!!! (do not over-fill ) . if everyone did all these before winter & or inspection time, they wouldn't have the problems they get.

Depending on the mileage it could need a few things. Your basic tune up will include replacing the distributor cap & rotor, ignition wires, spark plugs (6), and the fuel filter.

You always have to at least check spark plug gap

In 47 years, I have never seen a set of plugs that were not
knocked around & the ground electrode bent, on at least
a couple of them

You can clean a rotor & cap & get 3 years out of them,
no need to replace until they get too corroded

Wires last 15 years no problem
Don't get caught up in all the hype & tune-up non sense

The gap is on the radiator support label

The coil has to be tested,you don't throw parts at a problem

If it doesn't start, it has nothing to do with rotor,cap,plugs or wires

You could throw away 2 plugs & it would start on 6

did you change the fuel filter? make sure all plug wires are on the right plug If the coil wire was crapped out the other wires may me too. look at the inside of the cap srpray some wd 40 in it and wipe it out good make sure top of rotor is clean too

You may need to give it a general tune up, including spark plugs, wires, and cap and rotor (if applicable to your application.) Sounds like there is crud on the plugs.

Tune up should include.Plugs,distributor cap,rotor,air filter,fuel filter,if plug wires have never been replaced then replace plug wires,pcv valve.Use good name brand parts.Don`t get cheap stuff.Make sure and gap the plugs.The specs.decal should be under the hood or on the hood itself.The plug gap is .045.Also use die electric grease on plug wires.It is usually supplied with wires.Hope this helps.Good luck.

A tune up is generic. i don'y have specific part numbers or anything, but a tune-up generally consists of:
Spark Plug replacement (6 of them)
Spark Plug Wire replacement (6 of them)
Fuel filter replacement
Air filter replacement
On older vehicle, one would check all the components that involve spark, such as distributor cap & rotor. You might not have these, yours may be computerized, no service required until it fails.
A tune up would also include a review of all recommended service items as noted in your owners manual. Some of these might be mileage related. Such as, timing belt & transmission fluid replacement.
I normally do not do tune-up's unless the vehicle is having a problem. If you end up taking your vehicle to a mechanic to diagnose a problem, he will suggest many of these items before beginning his diagnosis.

System, Tune-Up B 0.0 3.8 Notes Includes: Renew & Adjust Spark Plugs. Inspect Or Replace Distributor Cap, Rotor & Ignition Cables (Where Applicable). Service Or Renew Air, Fuel Filter And PCV Valve. Adjust Ignition Timing And Check Advance. Make Necessary Fuel Adjustments, Service Battery. Does Not Include: Adjust Belts.labor book gives 3.8 hrs x labor rate of the shop. parts will vary depending if they are Jaguar parts or after market

U are correct, a 'tune up' is not an oil change, although the oil certainly can be changed at the time of a tune up (every 3k miles or twice a year if u don't drive much, and always change the oil filter too). Cars differ, mostly older to newer as to what can and should be done for a tune up. A car from the 1960's would need more parts replaced more often than a new car today (example: electronic ignitions of newer cars eliminate ignition points replacement, and generally, replacement is not as often of other parts: example, spark plugs).
So, a tune up can include spark plugs, wires, distributor cap, rotor, and I would include fuel and air filters. There are exceptions to this too, making it more complicated to generalize what to replace, as wires and spark plugs can last 100k miles now, some vehicles don't have the traditional dist. cap and rotor to replace. Check your car owners manual for an idea of what to replace and how often. If u don't have the original owners manual, check the car manufacturers web site for info. Good luck with the tune up!
