hi i am new to this please help me i have got a 1998 k11 it starts up fine and will tick over all day but when i try and rev it the revs goe up and down i have fitted a new throttle body from breakers it woked ine on the other car i tried it but still no joy.
i dont think its a misfire it just revs up a little bit then dies down it doesnt cut out just revs go up and down when you press throttle.
this is realy all new to me can you tell me were the maf plug is which one is it thanks
