Q: E85 flex fuel sensor
Please advise- will a faulty flex fuel sensor cause my Suburban to stall out when its warmed up? It starts back up, I can drive off, then it will stall again. Maybe its something other than this sensor. Thanks!
My car has 150000 miles.
My car has an automatic transmission.
The E85 sensor can give the engine computer the wrong indication of the type of fuel being used and the ignition timing will be incorrect. This can cause stalling, hesitations, rough running and other symptoms.
