Stalls upon startup or driving
Good morning guys, hope you’re having a good day so far. I need some help in having my mom’s car fixed. She has a 2008 Honda Accord i4 auto with 147k. Her car has been stalling upon startup and as of recent has been stalling while she drives. When she brakes and takes a turn or when she’s at a stop. We did change the Crankshaft Position Sensor (OEM), Spark Plugs (OEM), Ignition Coils (OEM) Starter (OEM), Mass Air Flow (OEM), and Air Filter. Throttle Body has been cleaned, and had a mechanic test the fuel pump and results came back normal and there is no air leaks anywhere. I, along with mechanics are stumped and don’t know what the problem is. There’s no check engine light codes either. Is there anything else that we’re missing to check that can cause this issue? It’s very dangerous and is a safety issue for her going down the road and for others as well. Thank you guys very much for the help in advance!
Something else to consider. Some Hondas had a problem with the ignition key wiring harness. This could cause random stalling. There was a recall for some years and models. I'm not really sure how to go about testing it. But buying a new wiring harness would be kind of expensive, if you could even find the part. I figured that my ignition key wiring was probably OK since it cranks the engine just fine, even when I can't start the engine.
