Toyota Corolla 1999 code p0301

My engine light is on. I have checked and know that it is the misfire of the cylinder 1 and the code is p0301. I have changed the spark plung, spark plung wire and igition coil but the code still comes back. Is any one can help me to fix the problem, please?

    Great answer, Toyota Ed. I found this searching on P0301, thought it might be worth mentioning - http://www.obd-codes.com/p0301

    The next two steps are to determine if the inhjector is working (is it clicking with the engine running), and a compression test. You have ruled out all 3 of the main possibilities, the only thing left is injector, compression or wiring faults.

Were your plugs oily when you took them out?The reason very often is leaking valve cover gasket. If the gasket is leaking even slightly in the plugs cavities, the oil will ground the spark plug shorting the circuit and throwing misfire code. That is why, the problem reappears when you replace your spark plugs, injectors and ect. New valve cover gasket solves the problem.

What causes the check light to blink, a rough idle at times and hesitation in a toyota altis( corolla) 2003 series


a blinking check engine light usually indicates a misfire. It could be a bad plug, a bad coil, a bad wire, or a condition known as carbon tracking.

Pull the codes first. This will narrow down what cylinders are being affected. I'm betting you have one of these codes P0300, p0301, p0302, p0303, or p0304. The last number of the last four i listed are the specic cylinder that a misfire is on.

Let me know what you have for codes.

Let me know if you have any questions. Thank you for using FixYa.com!

Chech engine light code OMDII 300 vehicle back fires from stand still till speed 35 to 40 mhp 1998 corolla can you help


OBD II 300 Random/Multiple Cylinder Misfire Detected

When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.

Possible Causes:

Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues
