Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.
Your check engine light flashing means the computer system is seeing a direct engine misfire on one or more of the cylinders. When the light flashes the computer will detect it and set and store a fault code and or codes for the misfiring cylinders. In order to determine which cylinder is dropping out you need to start first with having the computer system scanned to retrieve the fault code and or codes. Most parts store such as Auto Zone will run a scan you you at no charge. If you can get this done and post back with the results I can advise you from there. In most cases this is either a failing spark plug and or coil.
Please do and post back with it and we can work from there.
Can you give me the actual fault codes that you got when it was scanned please?
The code P0174 is a lean code and not an Oxygen sensor code and in most cases this can be set due to either a fuel pressure concern and or an engine vacuum leak and in some cases even dirty injectors. Is the engine still misfiring on 4 of the cylinders?
Okay what was the code that sat when the light came back on, was it the P0174?
Thw bad coil would explain the check engine light flashing for sure.
Is the code still the P0174?
If in fact it is this code is not a HO2S sensor code but in fact a lean code usually set in most cases due to an engine vacuum leak on bank 2. Let get it rechecked and work from there.
Your very welcome, Ill be off this morning but will check back in this afternoon if you need me.
