This is defiantly an ECM issue. unfortunately, this is a dealer part and, you will need to order ti fro a local Toyota dealership.

the ecm controls all ignition timing with the help of a few sensors(CKP,CMP).

The symptoms you are describing, are the direct cause of a fualty ECM.

I have a 2000 Dodge Stratus with a random misfire on 1,3 and 5. The engine runs fine besides a twitch in the motor that can be felt while idling. Already replaced plugs and wires. Suggestions?


get the OBD codes read this will tell you which switch/sensor is causing the issue , the last random misfire i encountered turned out to be low cylinder compression so if the OBD code says " random misfire " then get the cylinder compressions read , hope this helps

Random multiple misfire P0300, P0302, P0304 on 2006 Kia Rio


A competent mechanic will check all probable causes associated with these DTC codes.
Code P0300: Random-Multiple misfire detected. Probable causes:
1. Vacuum leaks, damaged hoses, or improper routing
2. Fuel contamination
3. Ignition system - Ignition module, coil, spark plugs and wires
4. Fuel system
Code P0302: Cylinder 2 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system
Code 0304: Cylinder 4 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system

Be sure the invoice enumerates all of these probable causes as having been checked. Also, some of the replacement parts installed earlier may be faulty.

Need some more info on some diagnostic codes that came up on my truck & how to fix them. P0137 o2 sensor, P0300 random multi miss, P0303 cylinder 3, P0306 cylinder 6, P0307 cylinder 7


Replace your O2 Sensor and Spark Plug Wires. If you still have the Random Misfire, replace your Spark Plugs, then Replace your Distributor Cap and Rotor. If you still have the Random Misfire you may have a Timing Problem, or Ignition Coil problem.

Piston missing code 0300 comes up 2000 tundra on 90,000 miles


po300 code is a random cylinder misfire. start with checking the plugs, plug wires, coil packs, make sure no plug wires are touching exhaust manifold. If it is none of these you might want to take it to a mechanics shop or dealer. might be something internal like leaking valve/s, start with the simplest things hopefully you can find problem.

6th cylinder misfire. replaced spark plug and ignition coil 6 months ago and already misfiring again.Is this a problem with 2000 toyota tundras or is this normal to have to change spark plugs and ignition...


Did u find code p0306 comes up ? Two things can cause this if the plug and coil have been replaced.the intake manifold may be leaking in the area of cyllinder 6 or its a mechanical issue.try doing a cyllinder misfire test and also check the compression on all cyllinders

I am showing a #7 misfire on my 2000 tundra v8 4.7l. Have changed sparkplugs and still have same problem. Is there a way to test this ignition coil?


You can switch ignition coil to the other cylinder to check if the misfire follows that pack. Or check for ohms.

96 bmw 740il misfire


This is a pretty common problem. I would change your valve cover gaskets. They run around ~ 50 bucks. If they are bad it will leak oil into spark plug well and cause a misfire. Very known on the 740.. Also if tune was not anytime not too long ago id change spark plugs while you at it. Then clear the computer and if you still get misfire on 8 try changing the ignition coil which is right about the cylinder with cylinder ignition coil 5. clear the computer. if you get random misfire and misfire cyclinder 5 after then its your ignition coil. parts store runs around 100 bucks

Random Cylinder Misfire


The problem is the ignition control module such is under the coil packs. It seems to be an internal problem in the design. I have seen it many times and if you don't belive as many will not. So disconnect the modules electrical connector and just let it sit for two to three days. After that clean ir replace your sparkplugs, they will be fails up dew to it running lean and rich. Plug it in. Plug it in and wala its fixed $ but only for a week or two then back to the same thing so in short change the ignition module and save time and money, and don't forget to thank your friendly neighbor hood mexican mechanic.

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.
