BMW 530i 2001 engine struggles under load

For the first time yesterday, my 2001 530i BMW struggled when going up a modest hill and lost power when I pressed the gas pedal. Could this be a bad coil pack or a fuel pump? How can I tell for sure?

If a coil was bad, it would be missing or misfiring. Could be a clogged filter or a weak fuel pump. To check have the fuel pressure tested. If pressure is good, a tune-up might help.

SOURCE: struggle to go up hill

the problem exist when the car goes uphill regardless of fuel demand. this sounds more like a transmission problem, check ur fluid if necessary have changed, have ur transmission filter system checked.if it were in the fuel system u would expirence this problem anytime u put fuel demands on the motor. but as u state it happens when ur going uphill which is the transmission job

What are the signs of a bad fuel filter on a 2001 buick century

Hey Keith, you have all the signs of a blocked/restricted fuel filer. Will also struggle, especially going up hills if there is a missfire. Missfire will usually turn on engine light but sometimes not. If light is on and you have the system scanned it will tell you which cylinder to check. Mis fire codes usually plug,coil, or coil pack. I would try filter first if never changed.

2001 VW Cabrio temperature light is flickering

how long is a piece of string ? this is the answer because without head under the bonnet its very hard to diagnose ,it could be anything from a air flow sensor to a auto choke sensor so best advice is to ask a local mechanic to have a look for you see what they say .Sorry not to be able to give a nice quick answer but these modern cars are just too complicated nowdays even one as old as this

dump a bottle of carb/injector cleaner in the tank on your next fill up and just drive it, it should get better, if not the engine may be so worn that it has low compression.

I have a 2001 bmw 318 and a month or so ago i noticed a problem with it. when it was first started and driven it would struggle to pick up any speed but one it warmed up it was fine however now it...

I have a similar car with similar problem. My engine light is on and my mechanic says it has a faulty Mass Airflow Sensor (MAF). If you unplug the sensor cable you will notice a big difference in accelaration.
