    B5 passat issue please help

    Hello everyone,

    2002 v6 passat. Car would start idle at 500rpms for a second and die. This happened for about 10 min of intermittent trying. After that 10 min the car would then idle but unless I rolled on the gas very lightly the car would die. If I roll on the gas lightly and let it rev up I can release the gas completely and the car will go right back to idle. Any ideas?

    Fuel pump. Fuel filter. ??

    Replace the fuel filter in case it is old and blocked with dirt. Check the fuel pump is operating correctly.

    Id start with those items and then work from there onto spark, maf sensor etc if that does not fix the issue.

    Have you had a flat battery? These Passats usually needed a throttlebody alignment after a battery change.
