Repair P0301 Misfire P0171 Lean Toyota Camry √ Fix it Angel

[@spelunkerd]

OK so I'll add some dialogue as to what I believe happened. The car presented running rough, and was found to have a cylinder 1 misfire and lean codes on the scan tool. On freeze frame data the engine had not yet warmed up. The usual approach with lean codes is to run the vehicle with live data running and then open up the throttle to see if it improves. Improvement would point in the common direction of too much air from a vacuum leak. Here the live data verified the upstream oxygen sensor is cycling fine, and the fuel trim actually worsens with open throttle. Overall this points in the direction of something that would specifically impair fuel delivery to only cylinder #1, and the most common cause of that is a stuck closed fuel injector. When the computer detects too much oxygen in the exhaust, it responds by prolonging injector pulses to all cylinders on that bank, which caused three cylinders to run rich. Of course prolonging injector pulse has no effect on the first cylinder which wasn't getting any fuel, so it keeps increasing fuel. If the injectors were easy to get to I suspect he'd have done a few tests on the injector to look for a signal from the pcm, but he couldn't get at the injectors without removing the valve covers. So, he removed the valve cover gaskets to get at the fuel injectors, and he proved the #1 injector was bad by testing resistance. Then he replaced the injector and adjacent seals, he replaced a pcv valve while there, and put it all back together. The real message here is not to guess about the diagnosis, this is a real pro at work.

Yeah, I just ran into this. Mine started out with multiple misfires so changed the plugs and wires. Now I'm only throwing a code for cylinder one and pretty much determined the same thing. At least the job isn't too involved. a HUGE thanks for the no bullshit video editing.

I like your way of handling tools and components. I used to be terrified of handling car parts cause I didn't know anything about them. Now that I understand so much I can just throw things about and know what goes where and its very comfortable to work on cars. Makes them waaaay less intimidating.

Lubricate the o-rings on the injector. I use Vaseline on them. Keeps them from dry rotting and sticking to the metal next removal. It also makes installation easier.

[@nickv4073]

Vasoline is petroleum based and eats rubber. What you suggest is a mistake. You must use a silicone based grease on O-rings.

[@user-pj5ff6xw4x]

Just dip your o-rings in gas ⛽

Check if your radiator is full of coolant. if so, then check your engine coolant temperature sensor(ECT). It could be bad like this. kzbin.info/www/bejne/eoC7hqCnl7R8l7s Also try testing it. Remove it and see if it's not corroded or cracked.

[@lhpfla]

Very nice video. Well done.is that a new gasket for the camshaft cover, or did you re-use the old one? Also , the Toyota seal packing you only applied to a few spots...why didn't you apply it all around the entire surface?

how goes the engine Toyota Camry 2.4 VV-TI 2 AZ-FE?

[@rouge0449]

Hi Angel. I recently changed my 3SFE engine cyl #2 injector and I noticed that the spark plug turned carbon-fouled. I swap the cyl #1 plug with #2 plug to test and the plug from #1 got fouled and the #2 plug got normal looking (carbon got burned). #2 cyl seems to be the only one running rich. Tension wires are good, 4 spark plugs are new, coil is ok too, no leaks on fuel pressure reg. Any tip to make cyl #2 fire normal just like the other 3 cyls? Thanks.

[@tigergray1100]

I got the same problem on my Corolla so I replace all four spark plugs, coil packs, and fuel injectors . I also put new MAF sensor and a new fuel pump but I still get misfires on cylinder 2,3,and 4. I get codes like p0171, p0300, p0302, p0303, p0304. The car idles bad I took my car to a mechanic for vacuum leak test but it's normal. Can you tell me what's the problem what to look for? 1zzfe engine is pain in the ass. I like the v8 Lexus 1uzfe vvti a lot easier to work with

My Lola has a 2002 toyota camry Le and it shows Random misfire on 3 out of 4 cylinders and 171 lean...codes...I went ahead and replaced coils and spark plugs because she never had them done. STILL SAME CODES COME UP. MY QUESTION CAN A FAULTY FUEL INJECTOR CAUSE MISFIRE CODES ALSO... THANKS

[@FixItAngel]

Hi Lito, yes it can be bad fuel injectors or it’s plugged up.

it would have been a better video if he would have called out each part he was replacing. but so far the best video on this particular engine. Which is the same one I have.

[@CHIBA280CRV]

Nice job , but how did you know it was the injector ? You did not do a injector balance test . Thanks. Angel another fine video.

[@FixItAngel]

JOGO hi, the p0171 is a lean condition, less fuel indication. so I figured the #1 injector is clogged. Honestly, I never done a balance test. Maybe next time I will do that. I guess I got lucky?? Thank you for the question

[@VENUEATHENS]

Hi Angel, I'm getting the p0171 code on 2000 toyota sienna... I took out the injectors cleaned them with carb throttle body cleaner, changed the little filters in them and replaced O-rigs one top and bottom for each injecter.. I also did valve cover gaskets, and the spark plug seals, I also changed the spark plugs and put in a new wire harness for the spark plugs. I cleaned the throttle body, and changed whatever hoses that were old and hardened. . I also replaced the intake plenum gasket and throttle body gaskets. Before this god I was getting misfire for cylinder 2 and 5.. after replacing what I listed above it worked fin for a little while then I got the P0171 code and check engine light came on.. Perhaps the spark plugs for 2 and 5 were bad and it would be better just to replace them all.. Do you have any suggestions? Anything will be very much appreciated, it's my dads van and I'm trying to help him :(

[@FixItAngel]

Hi Tony, try cleaning the MAF sensor at the air filter intake tube. see if that works.

[@VENUEATHENS]

@@FixItAngel thank you, I will try that.. I noticed there are 2 sensors connected to the throttle body, attached by screws. I think when I sprayed cleaner in the throttle body maybe some of the gunk got on those as well

[@VENUEATHENS]

@@FixItAngel I'm really sorry for such a long reply, I just wanted to be thorough to what I did to the car.

[@l.w.f.c3291]

Very nice video. Love the fast forward and camera work was very clear. I have the same error but not a misfire error. I changed the big rubber snorkel to the throttle intake. I never reset the error though. It does give me trouble every morning I need to spray starting fluid. Or it won't start. Any idea? I put injector cleaner in fuel but did not help. Any thoughts for me?

[@FixItAngel]

Reset the check engine light by removing the negative battery terminal for a minute and put it back. drive it and when the check engine comes on, tell me the code.

[@kevinkidneyy]

You the GOAT

[@liam71rock]

Did you de pressurize the fuel system at the pump/filter or was that the EFI fuse removal step?

[@FixItAngel]

yes, I removed the Electronic Fuel Injection(EFI) fuse.

[@liam71rock]

88bmyvegas Thank you so much for the video. It was well made and explained the process well. I did have fuel spill from the injectors when I pulled them but no pressure. Popping the fuse was SO much easier than the Haynes manual method. This job took about an hour and that was with sending my son for a new valve cover gasket and replacing the seals/grommets on all the injectors I wasn't replacing.
