1989 Trooper Engine loss of Power

Asked by Jul 07, 2018 at 04:05 PM about the 1989 Isuzu Trooper

Question type: Maintenance & Repair

I have a 1989 trooper.  It runs very rough and has no power and struggles to
go 20 MPH.  It idles, does not smoke but has rich gas smell to exhaust.  It just
will not go.  Replaced, fuel filter, EGR valve, cap, plugs, vacuum lines and it
has no catalytic converter.  Any clue as to my problem?

Temperature sensor is faulty and sends signal to shut the air. So you flood the engine. After you replace the sensor change the oil. There is gas in the oil now.
