The po300 is a misfire code.This means there is probably a plug,plug wire,ignition coil,or ignition module.Check the coil towers one at a time.These are know for corroding.If you find one that is corroded then replace the plug wire also.Po171 is a lean condition code.The po300 could be causing the po171.If you have not had a tune up Now would be a good time.Hope this helps.Good luck.

I have a 2006 Pacifica touring and the following error codes: po700, po562, po736; po732, po731 and po,720 and po480. Can you tell me what I need to fix this?


With that many codes and those specific codes I would suggest finding a reputable transmission shop. I suspect either a wiring issue or a bad trtransmission control module. A good shop should be able to determine which in just a couple hours or so.

Gm code po300


This is a misfire code. Start with the basics, fuel filter, spark plugs, vacuum leaks, wires etc. If after checking/changing necessary parts, if problem persists you will need to go deeper as in coils and computer controlled parts such as map sensor, maf sensor

2000 Lexus GS300 I have codes po300 po302, po303, po304, po305, po306,po171


We can't help you here

You need the car diagnosed

I doubt you have lifters,should have
OHC valve train

Most likely the oil passages are clogged up
in the cams with sludge

That's what happens when the wrong oil
& too long between changes takes place

You ruin the engine

Fault codes, PO300, PO171 and PO174


The Po300 is a random misfire code where the PCM is picking up the misfires. The other two codes are lean mixture codes. More than likely these are due to bad intake manifold gaskets allowing unmetered air to enter the engine causing the engine to lean out and possibly run a little rough when cold.
