1997 XJR Throttle & accelerator cable adjustment. 70% max Open throttle
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 🙏🏼
