#1 of 3 2000 Isuzu Trooper possible misfiring by izuzu2000 Oct 26, 2007 (12:23 pm)
I have recently had a new engine put into my 2000 Trooper (dont ask me why) I haven't driven it for a month and it drives great. However for the past couple of days whenever the car is in motion the check engine light blinks on and off and I smell gas. I know this means problem so I call Isuzu service and was told its misfiring. That was a couple of days ago. Today I back the car out to find a pool of what smelled like gas in the driveway and the gas gauge seems lower and then when I put the car back to the original spot there is another pool in the place the car was in park. Does anyone know what may be the problem and does the car sound safe to drive to the dealership?
#2 of 3 Misfiring? by dragonroly Jan 09, 2008 (9:20 pm)
Hello,, I had a check engine light on my 2000 isuzu trooper where the code fault mark the EGR valve that i replace fixing the fault. Now, 3 weeks later is stalling when stop and or in "park". While running and normal speed works fine but the check engine light flashes on and off .The code marked is PO405 and PO300. Could this be another faulty sensor or does the coil or Spark Plugs needs to be change? Replies to this message: brentb1 (Dec 26, 2008 4:40 pm)
