hi there my i have a prob. when i accelerate hard in say 2nd gear then change to 3rd my car will hold back like its ran outa fuel then come back then same will happen in 4th etc. this can also happen if i boot it off the lights in 1st then change to second. when i driving normally it fine. also if i stop it and go into a hop for example then come out and try to restart it , it will start but it will cough and slutt if you leave it for bout 15 seconds the revs go up to bout 1 500 then come back down to normal and off i go, if i try to rev it while its upset it jus backfires and trys to stall. can anyone help cheers
