hi there.
I HAVE A PROBLEM WITH MY AUDI A4 1.8 SE 1997 WHAT SEEMS TO BE HAPPENING IS THAT WHEN ITS COLD IT IS A PROBLEM TO START AND ONCE THE CAR IS STARTED IT TICKS OVER OKAY AROUND 800RPM BUT AS IT WARMS UP WHEN YOU ACCELERATE BETWEEN 800-2000RPM IT MISFIRES/BACKFIRES AND IS USELESS ON THE ROAD,YOU CAN PUT YOUR FOOT DOWN AND NOTHING HAPPENS UNTILL YOU HEAR A SMALL POP/BANG THEN IT TRYS TO ACCELERATE,BUT HAS VERY LITTLE GO IN IT I HAVE REPLACED THE FOLLOWING

AIR FILTER
THROTTLE BODY
COIL PACK
PLUGS
MAF METER

AM WONDERING IF IT COULD BE A FUEL DELIVERY PROBLEM IE; FILTER ,PUMP,INJECTER,ETC HAVE TAKEN THE CAR FOR LONG RUN ABOUT 15-19MILES TRY'D OTHER TYPES OF FUEL NO LUCK PLEASE ANY HELP WOULD BE GREAT .CHEERS MICK FROM UK

STOP YELLING!

It could be a fuel delivery problem. You dont have a CEL? Could also be a bad turbo. First things first- get your ecu scanned for fault codes and post them here.
