Sounds like bad fuel, vac leak, or fouled plugs to me. Clean the plugs, check the leads, check the christmas tree and all the hoses that come off it for possible vacume leaks and if all else fails grab some carbo clean and give the carby throats a spray

Could also be a sticky needle and seat causing it to run very lean. Remove the air cleaner lid and see how much fuel the accelerator pump is delivering. The idle jet on these Webers is also solenoid controlled. Some are electric and some are vacuum Edited by user Tuesday, 5 August 2008 10:39:21 PM(UTC)

If it's EFI then it's still running lean by the sound if it (backfiring). Check for vacuum leaks or a split ducting between the air flow meter and throttle body.
Modern crap fuel does not take long to go off. remove the fuel cap and have a smell. If |
