Oh, if you happen to have OBD monitoring hooked up, monitor ignition advance as well.

 

I'm with police666. Earlier S Types had problems with parking brakes binding. It was pretty much licked by 2003, but you never know.

And while it is reasonable to initially think that a car with a a dirty air filter would get worse gas mileage, think about it for a minute. The car automatically compensates for restricted airflow from a dirty filter (MAF sensor), to maintain a near stoichiometric (sp) ratio. So as air flow decreases, so does fuel consumption. So long as you did not try to compensate for the reduced performance, wouldn't you get better mileage?

Or would it be the same?

I am confusing myself here.

 

You're joking of course

 

Would this code be displayed anywhere? Or do I need a code reader (which I am planning to buy)

 

I've got them at 38, as per the door placard for a fully loaded car.

I don't currently have this capability, I'm reading up different threads on the forum relating to OBD-II, but I must admit I'm a touch confused with all the different posts!

I carried out the EPB re calibration procedure as detailed elsewhere on the forums two weeks ago, sadly it didn't seem to help

Pressures are as above, tyre sizes look to be correct as per door placard, they are mismatched brand wise though, pirellis on the back, some brand Ive never heard of on the front, all of them in good condition though.

Thanks everyone for the ideas! Very much appreciated!

 

NO.

 

One more test ... covers epb calibration and a whole bunch more ... how hard is it to push with engine off in neutral?

Don't try this uphill

 

No point using anything but 95. You're just wasting money. People really don't like to believe this.

22 sounds too low. I get over 24 in my STR.

Get an OBD tool with live data (like an elm327) and at least check a ton of things are plausible. Everything else will cost more.

 

OK, have just ordered an elm327 from fleabay, should hopefully arrive before I head down to Somerset

 

Grant wrote the 98 RON thing to see who, other then the usual suspects, would take the bait. We all know that extra octanses only works if you add at least 5 different randomly selected miracle-in-a-can additives from the local FLAPS.

 

I think ... in fact, I know that Grant is perfectly serious in his assertions with regard to both octane and ethanol.

Furthermore, I am in agreement for the reasons stated in multiple other threads in great excruciating detail. The "you're joking of course" was a feeble attempt at sarcastic humour.

And no snake oil thank you very much.

 

Maaaaaaate.

I just got a nice 750ml Grants Whisky from teh wife for being a "good boy and sorting the brakes on her S Type", so later tonight the keyboard is going to look real weird.

Sense of humour, again, I am the weirdest I know, having gone "upstairs" twice in '92, thanks to a work accident, I have the strangest outlook on life.

YOU ARE A LONG TIME DEAD, AND YOU DONT COME BACK FOR SECONDS. Mess this one up at your peril.

I reckon the "octane science according to Grant", from actually driving the car/s on each spec for 20000kms at a time, and not theorising (whatever that word means) is really SPECIFIC mainly to my XJ-S V12 HE, an ancient 1985 beast, and NO pollution rubbish, hell it dont even have a balance pipe, AAV, PCV system, and certainly DID NOT come with O2 sensors. Basically one step above carbies. Knock sensors, in your DREAMS, Engine management, same DREAMS, its got a Lucas distributor for heavens sake, and we all know their "fine tolerences", dont we??.

I reckon it "may" apply to the AJ16, and certainly the S Type, but at 4c/ltr difference, Grant DONT CARE.

Snake oil, nah, got lots of dead snakes here if you want some to make oil, HAHAHAHA, and I only had one drink.

Ethanol, feed it to the pollies, they need all the help they can get.

 

Oh noes!

 

Glad to see our newer member wearlej also has a sense of humour.

 

OOPS.

Time to go service the X300 ready for the Christmas migration.

 

I do indeed

 

I've been looking around at sites like (for example) Service Parts | Jaguar S Type | British Parts UK , to try and figure out which manifold gasket I need to buy for when I replace the spark plugs this weekend, I'm not entirely sure which one I need, can anyone point me at the right one?
Cheers

 

OK, had a look at the air filter, it's pretty much brand new, so that doesn't seem to be the problem.

Waiting for the elm thing I bought from ebay to arrive before looking at next thing.

 

OK, finally managed to get back online, I went for a run and logged the fuel trims. This log is from a cold start to driving home along the motorway. Any advice on the attached log?

 

Just in case anyone was interested, so far it turns out that the car had the completely wrong plugs in it, in the end I just left it with an Indy for the day for a service and new plugs, so I don't know what plugs were in it. Even the heat range of the plugs was wrong apparently.
I'd still be interested in anyone can help with the log I posted above.
