In Reply to: 94 540 rough start any tips? posted by george on April 09, 1999 at 18:51:10:
Could be leaky injectors, clogged fuel filter or if you overfilled the gas tank, the charcoal canister may be contaminated.
: My 1994 540i automatic has been starting a little rough the last few days. I live in the SW and its garaged, so it's not due to cold weather. What happens is it turns over then it seems to struggle a bit to get to full idle(thought it might be the battery). Rather than turning right over there is about a 5 second period where it seems like its grasping for air or fuel.
: This only seems to take place in the am. In addition it seems to take a little while to warm up in the am. before the throttle responds appropriately.
: Is it a gas problem(bad gas) an injection problem or what?
: Anyone had a similar problem.
