Thanks for the tip very helpful I have a Mazda 6 ,your right there picky
Was injectors the problem or just the plugs?
Awesome Videos. Got a question, 2003 Mazda 6 2.3l AT, car misses at idle but smooth at about 3K rpm, pedal response not good, but noticed at idle fuel injectors 1 & 2 not pulsing open for gas , work when step on gas pedal only. swapped throttle body, swap injectors, gas pressure good, compression good, replacd camshaft & crankshaft sensors...last is ECM..Any ideas on what to look for before replacing ECM?
What was it?
Can you please do a video on a mazda cx7 2.3 pcv replacement
2.3t cx7 Question i have a misfire on cylinder 1 “spark plug ,coil fuel injection ,intake gasket ,pcv valve installed . Still have code says permanent shop erased it and came back on - what else coukd it be.? Ecm.?
Yeah ecu, having the same problem with my mazdaspeed3 I'm going to change the coils but it seems like it is probably gunna be ecu. That's just a gut feeling i have lol
2011 mazda 3i has p0300 permanent on odbII scanner. when the key is on and engine off, engine light flashes 7 times. when the engine starts or the check engine light disappears. engine light doesnt return. what is the issue here?
Excellent, Lots of help. thank you
Useful info for my 98 MPV - thanks, guys!
I have mazda 2 2011
I have suffered from code p0300 random misfire. I changed the spark plugs and also changed the fuel pump but the misfire remained. I dont know what to do
Clean your throttle body. It controls just about everything
Did you check the ignition coils and the wiring harness they attach to?
What was it?
Egr
Cool!! Easy explanation! Concise and easy to follow
Awesome channel
Brand new Spark Plugs are pregap for specific cars.
Hello, thanks very good video, but what if you already changed the spark plugs and even the injectors, you drive the car and the same problem continues to come out, would the oxygen sensor and the catalytic have to be changed?
I just encountered the same issue. Crazy as it sounds, check to make sure the harness that attaches to the ignition coil clicks on and isn't faulty. I had the clip on mine break so it would lose some contact
I replaced all of that and more,still does it,its pointing towards ECU from this guys other video. But definitely check harness connections and Dielectric grease them to be safe.
I have a mazda 2 2014 it was on empty I put gas in it it started misfiring
mine premacy fs-ze p0300 after topoverhoul the engine... before that its overheating.. any ideas? its been a month now.. low idle almost dead
Hey, I'm having the same problem with madza cx 3 , but diesel engine.
Just changing the spark plugs and maybe coils is a big gamble with these engines. This will not fix most of the misfires on this engine
it can only be so many things,, usually a coil or vacuum leak when its random
What does?
@@KollynJfuel injectors
Thank you for the video.
thank you
Please, what is the code of Spark Plug for Mazda 6 2009?
Excellent!!
Helpful video
I have a 2013 Mazdaspeed 3 with same code.
What was the answer?
Nice one good job
my missfire stops when i disconnect the hose from throttle body
Most likely injectors or the seals that go on them.
This is great
My problm there are two code p0300 and p0304..change coil and plugs but the code still come back after 3days. What might be the problm?
I got 0300 and 0302. Did fuel filter, battery, cam angle sensor,
My car threw the same codes (but p0303 instead of p0304) and it was ua-cam.com/video/I9Lz3U4CuT4/v-deo.html
Did you guys figure anything out? I’m going to look at car that has same code
@@stevmarc5425 what was it?
