The 300 codes are misfire codes, do a tune up and that should fix the problem. the 155 i will have to investigate and try to see what it is.

2003 acura tl error codes po301 po302 po304 po306 p1399 po300


PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

If a tune up (spark plugs, ignition wires, distributor cap/rotor button or coil packs) don't work, try checking the fuel system.

I have a 1996 crown vic i need to know these trouble codes po301 po304


PO300 Codes-- are cylinder misfires

PO301 thru PO308

Last # is the cylinder

Could be bad ignition coil for a cylinder
or a coil pack for that side,depending what
engine you have

#1 &#4 are at the front & back of the passenger
side of your motor or firewall side if transverse

You will need to provide details of who worked on it
& exactly what was done besides replace a coil based
on a code

Codes aren't very good with COP Ignition but a complete
coil pack on one side should take care of some issue

Vacuum Leaks & other items can cause misfires & the codes
don't tell you to replace ignition parts as you may have

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

What's your problem? my 2004 mercury monterey has eight codes ,po301,poo53,po106,po316,po300,po304,po305,and po306


PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.

On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.

Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.

Hope this helps...
