Question about 2000 Jaguar S-Type

1 Answer

Misfires when the engine warms up

This is a 3.0 liter engine and the problem has gotten progressively worse. The car has 82,000 on it so I assume it was plugs, changing the plugs made no difference. The problem is particularly noticeable when shifting into OD.

Any suggestions or help would be greatly appreciated.

Hi Ron

Sounds more like the ignition coil pack (coil on plug) that is intermittently breaking down.

Whip out the plugs again, see if you can see one slightly oily, or abnormal.

If so, replace that coil and it should solve your issue.

Hope this is of help.


P.S. Don´t forget to give me a rating please !

I have a 1999 Ford Expedition and it started missing about a week ago and has progressively gotten worse, but it only misses when you accelerate or the engine gets in a bind (like going up hill) any...

How many miles? Have you ever serviced the spark plugs? I will assume it's a 5.4 V8, since it's more common than a 4.6.

In my experience with 5.4's, at about 120-140k miles, the coil-on-plugs tend to start dying. You will only feel the miss on acceleration and under heavy load, but may feel a slight wobble when the truck is at idle.
Not knowing how experienced you are with vehicles, I will give a slight overview. The traditional older vehicle has a single coil that delivers high-voltage to all of the spark plugs to cause the spark and ignite the fuel in the cylinders.
On these newer vehicles, each spark plug has it's own coil that is attached to the spark plug.
Unfortunately, there is no easy way to determine which coil is not firing without unplugging the wiring harness on each coil and seeing if the behavior of the engine changes.
However, in my experience, once one coil dies, the others aren't far behind. It may be worth your while to change them all at once.
The downside is, they are not cheap at about $43/ea at autozone. The upside, is they are extremely easy to change yourself. Simply unplug the electrical connector off of each coil at the spark plug. Then remove the 8mm bolt that holds down the coil. Pull off the sparkplug and replace.

I changed a full set in the parking lot of a hotel in South Fl last year, and it took me about 1 hour.

I have a 1996 crown vic with a police interceptor engine. It has began to miss really bad, it has 155,000 miles. Do you think it could be the plugs and plug wires? It has gotten progressively worse over a...

If the miss is worse when the engine load is high, I.E.- acceleration or in overdrive then it is very likely that you have hit the nail on the head with plugs and wires. They are very common for failure on the vehicle you have. Do NOT skimp, use good wires and the specific motorcraft spark plugs. (I am not usually a fan of pushing Manufacturer parts, but in this case.......) Also be on the lookout for vacuum leaks, another common issue on the car. Contamination breaks down the rubber and the elbows and hoses collapse, split, and leak.
Have fun. The plugs and wires will help you to learn patience.

Grinding noise about 30 seconds after starting

Sounds like starter isn't disengaging, get that checked pronto, you could be damaging the flywheel (very expensive). Could be any appliance also; a/c compressor, idler pully, alternator, etc. Don't wait.

Idles too low

A clogged fuel injector would make the engine shake, and your power would be compromised.
Whe you changed the plugs, did you put Toyota plugs in, or a different brand? More often than not, using any other plug than plugs bought at a Toy dealer can make the engine run worse. The engines are designed with a specific plug. Also, replace the wires if they are older than 5 years.
