Lexus engine check code P0305

P0300 is Random Misfire. 01, 03 and 05 narrows it down to those cylinders.

Clean throttle body and MAF, you may have carbon flaking off and fouling plugs. You could try taking it for a good thrash down the highway for an hour.

Replace the coil pack.

you have multiple cylinder missfire 1,2,3,5 check your spark plugs, plug wires and coils could even be a o2 sensor

Here's a link to your codes and causes.

P0301 Cylinder No. 1 Misfire Detected
P0302 Cylinder No. 2 Misfire Detected
P0303 Cylinder No. 3 Misfire Detected
P0304 Cylinder No. 4 Misfire Detected

P1349 Variable Valve Timing (VVT) System Malfunction

Stop driving immediately.....

You defiantly skipped on your timing........

You need to have the ecm scanned for codes. The VSC and TRAC OFF lights are one just because the Check engine light is on. Once you clear the code in the ecm they will go off too.

Hi, did you ever get an answer? I have the same issue. Thanks.

I have a 99 mazda B3000 with the 3.0l motor which is the same as the ford Ranger and I Had a misfire and it was caused by the camshaft sensor on the rear of the engine. It is mounted where the distributor should be but these have coil packs. My code was a po1309. If this helps any.

P0401 Exhaust Gas Recirculation Insufficient Flow Detected

P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0305 Cylinder 5 Misfire Detected


I would check out the EGR valve. That maybe what is causing all the misfires.

The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms
