I am calling the mechanic to get them directly.
ok Dan I got a call back...
Po300 random miss fire
These are all codes that keep coming back
It seems to be running fine. At an idle and highway speed.
I commute about 12 miles home in the evening. At about 3-5 miles down the highway the light will start to flash....go off....flash again....go off....flash again and about 6-7 miles into my commute the light will then stay on.
we had...not that long ago. I will ask him when that last happened.
wires, plugs, valve cover gasket replaced 7K miles ago. Sept 2012
Can sensor replaced @ 54K
coil pak is original
OK, I would suggest working on the P0300 code first, as that is a random misfire code, and misfires can cause other codes to be stored. 1. Tell him to check the compression on all cylinders and make sure they are within spec. and that the plugs look good that he replaced a while back. 2. If compression is good, with everything else you've tried, I would replace the coil pack as it is responsible for firing the plugs, and may be arcing or shorting out not getting fire to all the plugs like it should. 3. He can check the coil pack by spraying it with a solution of baking soda and water and then revving the engine and watching it. If it arcs or he see's any sparks fly out of it, Then I would replace the coil pack.
well I appreciate your thought on the p0300..the mechanic does not feel that it is the issue...it has only showed this code twice..... While we are still having the same 3 code issues even after replacing the two o2 sensors...what would be the next thought of where to look? Possibly poor connections, grounds ?
po057,po032,po038 are the primary three....
we have replaced the sensors for the 32,38
"po057,po032,po038 are the primary three....
ooops sorry po507
which I understand....that seems to be what is making it stall after my drive home.....
so let us talk the po032,po038
they are the 2 codes that still come back even tho they have been replaced
I have relayed this to him. How likely is it that the PCM would need to be replaced? At 72,000K miles even? I appreciate your input today and your troubleshooting from what I have been able to convey to you. If I need to come back and ask any more question I certainly will. Thank you Edward. Victoria
