Hey guys I got what I thought was a good deal on my puma but it's got a few problems with it a few are easy sorted like worped breaks and needs new bushes but while driving you start it up and it takes about 5 minutes for the revs to drop and when I set of I exellerate ( mind the spelling) take take foot off the pedal the revs stay high and if I put clutch in they don't drop the revs rise I we've had a diagnostic on it and it's a air problem but not sure we're to go from here
