P0300 and hesitation going up hills

[Rocket Man]

Get outta my mind!

Lmao just what I was thinking...

Thanks yaw! I last changed in 2017 and remember going through hell. I look more forward to this job now. I ordered the 41-162 from autozone with $7 discount and a mail in rebate I know i'll be too lazy to fill out. Came out to $62 before rebate. I'll record the misfires after I replace hopefully tomorrow and if the amount is still high, I'll work on the plugs next. Wasted my money on a spark tester

Glad you went with a reputable source for the plugs... I learned my lesson with Ebay/Amazon plugs. Too easy to get fakes, that's why I went with Rock Auto last time... plus they were the only ones that carried the Ruthenium plugs I wanted to try.

Yea my first set was from amazon. Maybe that was the problem. Reputable seller though, 4 stars....but the few $ saved isnt worth the risk I'm learning.

It’s fine when you buy direct from Amazon, it’s when you buy from a third party seller that you need to watch out.

Once you enable the PIDs then you will want to go back out and go to Realtime Information and long press on a blank screen and Add Display then choose which type, I use the Digital Display then you scroll down,like you did before, until you see Misfire Cylinder (X) current or history and select the one you want to see. Do this for each cylinder.

Dang, you just made my Torque Pro much more useful. Thanks!
Is there a webpage that lays these tricks out?

Your welcome. I'm not sure to be honest, I just get in the app and start playing around checking out all the different menus until I stumble upon something useful... lol

I just got the idea that the other sensors probably work the same way. Long road trip coming up, I'll play with when it's my wife's turn to drive.

Any suggestions on what to look for in torque app to test starting issues? I have another car that has trouble starting after it has been driven a little until it cools down. Narrowed it down to an evap canister or injectors issue. It never turns over unless it sits and sometimes helps to remove gas cap for a little while.

 

[Fless]

Are you saying that the engine doesn't turn over (doesn't crank), or that it turns over but doesn't fire up (crank but no start)?

 

[Meccanoble]

Cranks but doesnt fire up. This is for a Toyota Camry. Some say evap, some say injectors leaking and causing engine to be flooded with gas until cool off time and clears. When cool, starts up with no issues and drives fine with no issues. Turn off to run to the store and wont start up unless you let sit for like half an hour.

 

[Fless]

At least it's reproducible. I'd monitor the fuel pressure with a gauge to see if it leaks down quickly after it's hot, or anytime after you shut it off. That could indicate a leaky injector or bad fuel pump valve, etc.

thanks for the direction

The next time it won't start like that hold the accelerator pedal all the way to the floor (wide open throttle) while cranking the engine over.

If it is flooded this will clear the flood because it will shut off the injectors while cranking.

If this causes it to start up then the most likely culprit is the evap purge valve on the engine.

I'll try this. I normally keep pumping it while cranking but never held it down before starting nor holding it down the entire time.

Here are the old 41110 and new 41162. The rain is slowing me down but almost done. The trick worked great for cylinder 7 and about to start 8

 

[Meccanoble]

That Cylinder 8 is still tricky. I got it done but could not for the life of me fit the torque wrench. That heat shield all in the way. I gave it a snug fit and everything else went smooth. Fired her up and she sounded amazing and fired right up. Lately she had trouble starting. I went around the block and up a hill I commonly use for testing and issue is definitely gone. I have to do more testing to see if the wires or coils may have issues. Should have a better update on misfires after a spirited drive.

Thanks everyone, saved me some $ because I was definitely looking at replacing coils/wires first with the sad assumption that I had more time on the plugs.

 

[Meccanoble]

I was complaining about a stutter with the truck for the longest and blamed it on the transmission. This seemed to have went away as well but will confirm later today.

 

[Rocket Man]

Awesome! I sure hope your troubles are gone. Sometimes it’s the simple things. I remember when I had plug wire problems and thought the worst. I had those fiberglass heat shields on and they say they are good to like 2000* or something so I never thought of removing them from the plug boot and inspecting the brand-new wires (they were tight as hell on the boot and hard to get off) but I used my Tech2 and saw which 2 cylinders were misfiring so I did the troubleshooting procedure and when I swapped those wires to adjacent cylinders the misfires followed. Then I removed those heat shields and saw brown spots on the wires where the shield and wires were touching my headers. I finally bought super short wires that stayed away from my headers.

Me for the win!!!.... lol

Glad you got it sorted out and it didn't cost you an arm and a leg.
