Default Throttle a hair trigger.

2008 S-type, recently purchased, and the only complaint is that the throttle is "hair trigger" -- I literally have to accelerate with caution. I understand the throttle can be "trained" by disconnecting the battery, reconnecting and using a "retrain sequence" of pedal pressed. Is this so?

Thanks

Have not heard of that but don't see anything wrong with giving it a try?
What engine is in the car?
What did you use to drive? Sometimes your just not use to the how the new car operates?

When I first moved up to 400+HP Jaguars I felt the same way but my prior car had WAY less power. Now I have 600+HP but have no problems because I have had the car for a number of years.
I guess I just got use to it?

Probably is what Clubairth1 is saying. I have a Ford Escape 1.6 turbo for daily drive while i finish the Jag, and every time i drive the Jag i have to control my feet (is not as clubairth1 cars HP but i can feel the diference between one and the other and change my brain chip when i drive the Jag). Same with the drive train, i have always driven Front wheel drive, this is my first rear wheel drive and there's a lot of diference and little margin to make mistakes.

The ECM does learn your driving style and adjusts the throttle response accordingly. Dive it gently for a while and its responses will become softer.

Do I have to clear the ECM first or will it sort out my driving style after a while. By clear I mean disconnecting the battery. Thanks

It is continuous so will get there whatever but a hard reset will get you to the default setting immediately.

Mine tends to go a bit dull as I generally drive smoothly trying not to waste fuel. A few blasts up through the gears sharpens the throttle response quite a lot. Not sure how long it takes to go the other way though.

Good point from neilr! Be aware that the transmission will be a bit clunky too until it relearns things.

Thanks for the heads-up. My wife wants to drive it: her wheels are a RR Sport diesel; she already has a heavy foot... and she tends to follow too closely. So, until I can get this Jag to chill, she gets nowhere near.

It sounds like 300HP may be the problem for that particular way of driving.

It also sounds like it's behaving as designed.

Maybe one of those awful "chip" "tuning" things might actually helped if they can be adjusted in the opposite direction to the usual one?

The issue is from start: I touch the throttle and it GOES. I'll see if the learning curve can be dumbed down.
