Throttle has been heavy in operation, took throttle cable of and removed throttle spindle, this has 2 coil springs to return the throttle. Removed the inner one and reset the outer one and refitted, its as light as a feather now, operates as I think it should on a quality motor. Could have been played with before not sure, but for all of you who have early Volvos, mines 1997 and have this problem, appears an easy fix. :B_steerin

Nice one John, it's great when you get too the bottom of problems and fix them yourself without paying a fortune for the repair :)

Has this affected slow speed running? Is it now more responsive? Do 850's have this?

No, ticks over and works as it should, not sure if its the same as 850 perhaps someone else could advise. Because the pedal now is a lot lighter the car is easier to drive and definately more responsive as I now use more throttle with no effort, where before I seem to have to think about it, if you follow what I mean.

All looks the same as before, the 2 coil throttle return springs are behind the pulley the throttle cable attaches to. You take off the throttle cable and on mine kickdown rod(auto), remove the retaining circlip from the pulley and the pulley and springs comes away. Removed the inner spring and refitted just with the outer, making sure it is correctly tensioned up, job done, although very fiddly keeping spring in place when re-assembling, but well worth it.

I'll have to try that, my new manual cars throttle is really stiff compared to my existing auto and its not nice at all, I was gonna splurge on a new cable but I may try this first instead. Well done that man!!

Still unsure of what to do exactly? You say to 'Remove the inner spring and refitted just with the outer', so does that mean you dont refit the inner spring, and why not? Surely its supposed to be there!?!

Thought i might be able to do it without removing the sping (There for a reason) but still stiff as heel, anyhow, spring removed, seems smoother, still closes ok and misses is happy with it. So thats all that matters for me.
Cheers

Cruise control works fine, have to confess not sure what the inner spring is for, exept building up my thigh muscle.

Yes did not refit it, I suppose could be a back up spring, but as works fine without it, throw it away.
