My 1999 C230 Compressor was hesitating on heavy

Customer Question

My 1999 C230 Compressor was hesitating on heavy acceleration, so on a hunch I changed the fuel filter. I also unbolted the air intake above the intake vale to see if there was any buildup. Nothing - looked very clean.
Today the check engine light came on with P0170 code. Not sure what I've done.
I have any ODBII device and give you more information from the readout if it helps.

Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. Well first off make sure the fuel filter is installed correctly. There is a arrow on the filter to indicate which way the fuel flows. I believe your filter only has two fittings one in and one out. Also the code you have is usually caused by a air leak or vacuum leak. So spray some carb cleaner or brake cleaner around the engine intake while it's running and listen for a change in rpm. Locate that area that makes the rpm change and you will find your vacuum leak. Hope this information helps. Let me know if you need more info I will do my best to help. Lou.
