Hi guys
I’ve been trying to adjust the accelerator & cables on my 1997 6cyl 4ltr SC. I’ve followed guidance given by workshop manual (was given in a forum) that went something like..
”1. Slacken of both cables.
2. screw accelerator cable (long one) till pin on TCA touches the TPS actuator arm. (That part was easy as having removed the plastic cover on the Traction control unit i can see the pin and the “arm” it is to touch against.)
3. screw throttle cable to a 0.25mm gap between the two quadrants.

This raises my first question.. Where does the feeler guage go to measure this gap? so I just carefully tightened the throttle cable (short one) till the slack has been taken out, then backed it back off to make sure its wasn’t Too tight.

my OBD live data reader was showing 0.4% with no pressure on the accelerator pedal and 54% when fully open (pedal to the floor)

i spent a couple of hours adjusting the two cables as I was aiming to see 10-12% resting and 90-95% fully open. But could only achieve 12% resting and 70% open, and this just sends the idle speed to warp 6. (1200-2000RPM) so slacken off to bring the idle down.

My second question is simply, what am I doing wrong?

thank you all 🙏🏼

Hello, Jack,
Welcome to the forums from ElinorB.

Welcome to the Forums.

 

Hi guys
my name is Jack and I’m a Jagaholic
my current Jag is a 1997 XJR.
I rescued it from a scrap yard around 6 years ago and I’vebeen gradually fixing bits and breathing life back into it.
It now passes MOTs, but still needs a great deal of attention.
i guess the time and energy, and money.. would be better spent on tinkering a classic with a higher financial value, but this car has captured my heart.

I’m a full time musician based mostly in the UK, so as you can imagine work has been scarce this last two years.. but I tinker here and there on bits that shouldn’t break the bank to fix.

25 years ago I used to be a mechanic at an independent Jag specialist… the truth is I owned and ran the garage, but that was a long time ago so rhythm and timing take up more of my brain than Ignition timing firing orders these days.
But I’m sure there will be some areas that I can be of assistance.

My apologies if this post is once again in the wrong area of this site, I am somewhat of a technophobe and a bit of a Luddite.

nice to meet you all.

Jack

 

Thank you guys.
sorry I used the wrong thread for this!…. I dread to think where my ‘intro post’ might have been posted to.

I’m hoping I can contribute some knowledge to the forums as well as take from it.

thanks again for the welcome and all the advice.

Jack

 

welcome to the forum - enjoy!!

 

Jack,

It was worth the wait for a great Intro and it is in exactly the right place here in this thread. Your original question about the 70% Throttle max x300 XJR should go in X300 forum.

Graham

 

Thank you Graham.
I’ll no doubt get the hang of things soon.
