318ti: I have a 1998 318ti with 279000 miles Recently

Customer Question

Hi I have a 1998 318ti with 279000 miles
Recently it lost its acceleration ability
When merging onto freeway there is no accelation of any kind and forget going up a hill if traveling at a decent speed and having to slow down the car cannot accelerate so I hv to move to slow lane I'm not able pass cars for fear the car won't accelerate with enough speed to pass safely.
The cars RPM dose not move to 5 when pressing / accelerating the gas peddle
I took to Crevier BMW in Santa Ana ,ca but they said it's running they way it's been designed 🤔
Any suggestions how to resolve
I heard possibly the fuel pump? Spark plugs? Need Changing.
Thank you
John

Anything else I should try

I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
if the car is suffering a loss of power then the first things to explore are fuel delivery and fuel / air mixture.
the common issues would be low fuel pressure (fuel pump, filter, regulator), poor airflow (filter) or mixture faults (airflow sensor, air leak, o2 sensors, temp sensor)
I would definitely start with a new air filter, fuel filter and plugs and then move on from there with additional checks of the above
if you need a non dealer that probably works more with this age of vehicle I would check out www.bimmershops.com or www.bimrs.org for options near you
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
