Question about 2000 Lexus ES 300

Open Question

2000 Lexus ES300 code P1320 and P0505

Got codes for random misfire on a 2000 Lexus ES300. Changed all spark plugs and installed NGK iridium plugs. Checked resistance on all six spark plug coils, and made sure that best coils were installed on the three rear spark plugs (under the intake manifold). Cleared codes and ran vehicle. Got codes P1320 (Igniter circuit #5 malfunction #2) and P0305 (#5 misfire). The resistance on that coil is virtually identical to that of a brand new coil. Any ideas on what the problem could be? Thank you.

My Son has a 95 es300, the amp for it is located under the front passenger seat. The easiest way to access it is to remove the 4 bolts holding the seat down, and remove the seat. Takes about 5 minutes

I just changed the cabin filter of my ES300. I found the instructions on the manual, under airconditioning and audio. It's pretty easy to do. I bought the filter from Kragen's for $21.95.

SOURCE: hesistaton at idle speed. how many ignition coils are used in a 98 lexus es300?

I looked it up on AutoZone.com and it looks like there is only one coil.  You can verify that by giving them a call.  However, to me it sounds like you might be having a problem with your idle air control valve.  Since you are only having problems when the vehicle is at idle I would take a look at your IAC.  It is located on the throttle body and is usually held on by two screws.  When the IAC starts to go bad you will have problems with the vehicle when idling.  Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!

Back trace what you did. You may have unplugged something and forget to re-connect it. You mean the distributor cap,,,,, or the ENTIRE distributor???? If the later, then you must be 180 degrees off.

My 1999 lexus es300 is still reading the codes P0300, P0302,P0303 after giving it a tune up.


Your codes indicate misfires. What was done in the "tune up"? Misfires can be caused by any of several different causes including (but not limited to):
spark plugs
spark plug wires
coil packs
injectors
injector wires

The term "tune up" used to mean, "replace points, condenser, distributor cap and rotor, and plugs". Since most cars no longer have points, condenser, distributor cap and rotor, we need to ask what was done...

Getting a P0300 code. we have replaced all of the plugs w/ NGK Iridium plugs, changed the EGR valve, and one of the coil packs. It ran fine, but 2 days after the coil pack install., we are getting the same...


Have the fuel pressure checked and try replacing the engine coolant temperature sensor. If an engine is not getting enough fuel it can also cause a missfire.If the on board computer gets incorrect information from a engine sensor that is defective ( such as an engine coolant temperature sensor ) then it may set the injectors to shorten the fuel pulse width cutting back on fuel delivery and not knowingly be causeing the misfire its self. That to me would explaine the random misfire. I hope you find this helpfull. From Ernie @ RedDeer, Alberta, Canada.

See if your car has an ignition control module. They will go bad over time and cause random engine misfiring. Just went thru it with my 2002 Buick LeSabre. 120,000 miles on the engine. Replaced plugs, plug wires and check the coils. It was the ICM.

Code reader showes random misfire on cyl 1,3,5, have already changed the plugs


if the wrong spark plugs were used it could create a p0300 code. these cars call for ngk or nippon denso plugs. if i understand what you are telling me you have 4 related codes p0300(random missfire)p0301(cyl 1)p0303, and p0305. if this is the case then check your plugs again. if someone put in autolites to save money, throw them in the trash. they have a place, this is just not it. make sure your maintenance is up to date and the timing belt has been changed. it is recomended by hyundai at 60,000 miles.

P1320 trouble code plus


The P1320 code is essentially a coil primary voltage problem. This is traceable using a labscope or accurate DVOM and perhaps you can isolate one or two coils that still work but are close to failure...but there is a nissan service message recommending replacement of ALL coils with updated/improved models to prevent this type of failure. TCS/SLIP is traction control. Most likely you have a speed sensor issue. Be aware, some vehicles can falsely illuminate TCS because of low tire pressure in a single wheel.

P0300 is a random misfire code, if you are not mechanically inclined the first thing i would do if you havent done so in the past year or more, is change the plugs and wires, a random misfire code can be caused by worn plugs and/or wires not firing properly. let me know if that fixes it.
