about 3-4 weeks ago i had code p0420 so i had my catalytic converter changed. today i was ready to go to work and when i turned on my car it started shaking and i can hear the exhaust with kind of like a stutter effect and i noticed my CEL light was blinking. i did a little research already and i read it could be a misfire.

my exhaust sounds something like this

any advice on this? PLEASE HELP!

yeah, get new spark plugs.

DjDannyXL

Is that the only thing it could be?

check your spark plugs and coil packs. Usually, but not always, a misfire is a result of one of these. For more accurate responses, post mileage, last oil change, last tune up, and CEL codes.

DjDannyXL

Mileage is 81,800 last oil change was at 80,555. I got the car at 80,555 miles and i havent done a tune up. Dont know if previous owner did one or when. And CEL codes idk since i just started having this problem this morning b4 work. Would it be safe to drive it to autozone to get the codes read. Its about 2 miles from my house

I was also having somewhat of a rough but not to rough idle when stopped in nuetral or in gear b4 this happened. Its manual transmission

Yeah, you're about due for spark plugs. I got mine at 80k, didn't have any misfires, but changes sparks at 90k just to stay on top of it. It's not safe to drive with a misfire as you could blow your engine, but if you have no choice, drive slow and safe. Check your sparks and if they're bad, change them. Should only take you 30 mins, 15 mins to let the engine cool down, 15 mins to change.

Alright. Thanks for the help. I might not even get the code read. I'll just go buy some spark plugs and see if that fixes it since theyre not expensive anyway.

Get the codes read anyway. you never know when you have more than 1 problem.

DjDannyXL

Yea i am.. What brand of spark plugs do you recommend? I know theres like $5 spark plugs. Are those reliable?

Yeah, NGK should work fine. That's what I have in my car right now and no issues. You can get the Denso ones from the dealership, but NGK shouldn't give you any issues if you get the right ones.

DjDannyXL

How much does the dealer have them for? Meyers auto parts has densos for $11

Go to toyota, they run about 8 bucks a plug, total cost will be around 30 bucks. Toyota's plugs are good for 100k. Good luck with your issues!

hey dannyxl.. don't buy your plugs from meijer. we have meijer here too, and they're not that reliable with customers/kids throwing them around having "fun" in the auto parts aisle. Not a reliable place to buy them.

the part is from NGK part number 4589, you can get them from autozone, advance autoparts, oreilly.. they're about $8 a plug, called "Laser Iridium".

EDIT: the dealer has Denso parts branded as Toyota. The tC came from the factory with either NGK or Denso plugs. Mine came with NGK and I personally like the NGK better. I tried the denso, didn't like them, but some do, didn't work for me.

DjDannyXL

thanks for the advive

DjDannyXL

i made a quick video of the sound the car is making, just to see if you guys still think its a misfire b4 i go out and buy the plugs. let me know asap

Get your CEL codes read man, at least start there. Like I said, you won't really know what's going on until then. Your CEL isn't blinking anymore and I fairly certain a misfire wouldn't cause your exhaust to shake so violently.

DjDannyXL

im scared to drive my car to get the codes read. and i barely moved to nevada so i dont know anyone who might have one i can borrow
