classic kangarooing , help, advise
 

i was just driving and the car started kangarooing at first i thought my foot went on the clutch a bit then on the way home it happened again, got it home ok so i took my dad out in it so he could see what it felt like and then it dyed. when having a second look under the engine bay it looked like the smaller pipe going to the airfilter pipe had come away, so poped that back on and the car started, a bit chug chig at first then the revs started to idle as soon as i tryed to pull off it dyed and now wont even start
any idea's
or done anybody know a decent garage in cardiff
any help would be appreciated:wonder:
