Could someone please give me some information on these p-codes?

p0300
p1153
p1406

I'm afraid AutoZone was not very helpful other than pulling the codes. Although they did mention that p0300 was a misfire in multiple cylinders. I am planning on changing plugs and wires tomorrow.

I’m also looking for your thoughts on plugs and wires. One point of interest is cleaning the plugs. It has always been my opinion (with standard plugs) that some people could benefit just as much from cleaning the plug as they would from replacing it. I am not sure how this relates to the platinum plugs used by our cars. BTW I live in Dallas, TX and would appreciate any input on who might have the best price.

I would also like to add that I have had a lot of trouble with #6 wire getting burned up by the exhaust. I have used heat shield for plug wires, but it only seems to delay the inevitable. I have not seen this problem posted, so "I" must be missing something!!!. BTW does anyone know where to get plug wire heat shield in Dallas (I live in East Dallas)?

As always THANKS! for everyone’s help!!!

DTC P1153 HO2S Insufficient Switching Bank 2 Sensor 1

DTC P1406 EGR Valve Pintle Position Circuit



I would change plugs and wires first, then see if it still throws those codes.

 

Did the ses light come on before you had it checked? Or does it?

 

Hey, did you get that problem fixxed? My car's throwing the EXACT same codes. I replaced the O2 sensor, no go...
