hi guys, i have had a good look on this forum but cant seem to find what im looking for......

when i start my car from cold she ticks over fine , then as she gets warmer the revs seems to rise , after 5 miles of driving the revs are sitting at over 3000 . its annoying the whole street and me also. if i turn the car off at this piont it wont start again for at least an hour , sometimes it will start right away sometimes it wont .

it seems to get worse when the engines warmer . and sometimes the btrake pedal goes rock solid. always when the revs are high .

please help me people , i dont know what to do, i can only say that i ''think'' it might be a split pipe somewhere ???

mucho thanky in advance. PS . WOULD A DEAD BATTERY MAKE IT DO THIS ??
