#3 of 102 rough idle when stop
Jan 09, 2008 (9:16 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?

There is an ignition sequence that will help reset timing. You are supposed depress the accelerator slightly while starting it. Let it run for three seconds and then turn it off. Leave it off for 10 seconds, then restart. I did this and it seemed to help. Once I pulled the fuse for fuel system and started the car, but not sure if that helped reset or not.

got an initial idling problem. 6 cyl 2002 Rodeo. When cold, it won't stay running until I restart 4 or 5 times. Check engine light is on.. faults that showed were EGR and O2 sensor. Runs fine when warm. Any ideas? I don't want to just start replacing parts I don't need.

i cant remember if its throttle body fuel injection,so if it is you might want to check the iac[idle air contol] might be dirty with carbon,or need replaced hope this helps.ihis is for the 91.the newer ones with multiport will have the iac also but will give a code for it
#9 of 102 1992 trooper (sohd)

I just bought myself a new toy a 1992 trooper. it had some problems but it was so low on miles i had to take it. 112k miles. I changed the plugs, oil air filter, most of the vaccume lines, fuel filter, checked most sensors the seem to work, ran sea foam through out entire vaccume line system and break booster line, I think the IAC VALVE could be bad. The problem is when I want it to start I have to really be on the peddle in order for it to start. once started it runs rich a little bit of smoke and then has a fluxuation in the idle between 800rpm-1200 rpm's. ANY HELP PLEASE thank you

ok ive changed plugs,plug wires and plugs are only 6 months old.Changing the plugs got the rodeo to where itd crank but its doing as it did before it died,it will bog down and barely go,then check engine light comes on and it runs great,im thinking its cutting something off by default,then when it comes back on it starts messing up again.Does anyone know if im on the right track in thinking its fuel pressure regulator problems?ill change oil next cause i do have the fuel smell in the oil,hence the black smoke from exhaust
