misfire

I am having a cylinder 4 misfire. I have replaced the plug and the ignition coil, but still misfiring. Sometimes the CEL won't come on immediately, but after driving for a while (I still notice the engine is not running as smoothly as normal). Any ideas as to what this might be? Most of the...

My 94 FZJ80 starting to properly stutter/misfire and rough idled. Particularly bad under load. Initial thought was the plugs and leads so replaced them to no resolve. Then added 500ml Nulon Petrol System Extreme Clean (per instructions) and seemed to clear the issue right up. Having heard...

Hey All - Another highway shuttering/misfire thread..... I have read all of the past posts and have tried most of the solutions but wanted to post my particular situation to see another set of eyes could give some insight. Issue Between 50-60 mph at around 1800 rpm the car begins shaking...

1984 fj60 2f australia spec - I’ve been having a really annoying problem lately that i’ve been trying to chase, the car will run fine and i can plant my foot without any negative effects while it’s still warming up, but after an hour or a couple hours (it’s completely random) of driving the...

Hello all! Im looking for some advice with our GX470. The vehicle is occasionally misfiring on cylinder #6. I swapped over number eight number six coil pack and it didn't change anything. The spark plug seemed a little fouled so I put a new spark plug in. My p0306 code went away but the live...

Battery died, so I replaced it with a Duralast Gold 27F. + and - connections are correctly attached. After I changed out the battery, the LC intermittently but regularly shakes and lurches at low RPMs and in tight turns, and lights dim. Once I give it gas, its fine, but the rythmic shaking...

To those more knowledgeable and experienced, I’ve got 2f with a misfire on cylinders 1&2. I’ve been daily driving the truck since 2019, done a lot of work including a head rebuild in the last 5 years. I was driving a short distance around town last week and noticed the beginnings of a rough...

I took my 2000 LC to a shop to get checked due to a misfire on cylinder 1. As a preface, this rig had the motor replaced maybe about 170k ago at the Toyota Dealership, and it currently sits with 270 on the odo. The lady who sold it to me allowed some kind packrats to live in the engine bay for...

Hey all! 2005 that I have owned for the last 15 years. Currently sitting at 250k and I have started to get cylinder misfire codes being thrown. Started with and is primarily a cylinder 1 misfire but now includes other cylinders as well. -Generally only happens on a cold engine -Did change...

01 LX470 with 198K miles CEL started blinking while on a 1500 mile trip. Hesitation and slight shuddering when going uphill or accelerating (when giving it gas). CEL stops blinking when going downhill. Pulled DTC codes and P0307 comes up after clearing codes. [Also P0305 in history but I am not...

I have check engine light with loss of power and rough engine. Check engine light with code misfire on cylinder 3. This only happens when driving on interstate 65-70 mph. The truck will recover and run normal below 60 mph. I plan to replace plug and wire. Any other suggestions? Thanks

Hey yall! Long story short: overheated my 07 100 series, radiator blew, head gasket blew, replaced all of it (by the book(FSM)), immediately had rough idle on start up, only in drive and reverse at idle letting off brake, everything was solid enough to load up 3k pound trailer and drive 21...

Hey y’all, hope everyone is good on this fine Oct day. So I have a misfire that has me stumped, I’ve chewed through every misfire post mostly on here and even some others with vehicles that share my engine (2uz in a 2000 lx470). I’ve got a rough idle, regular throwing of a p0304. Weirdly it...

My fzj80 isn't running smoothly, slight misfire, ticking from the front/top of the engine. No CEL (sadly) and it runs okay. When the engine is cold, and I first start it up it runs absolutely amazing, no ticking, not misfire, no shaking. Once it warms up and starts reading the sensors it runs...

Looking for some advice on a persistent idle misfire I’ve got on my 2/70 1F. I purchased the cruiser a year ago and I’ve been a frequent visitor here to learn about everything FJ40. I don’t know much about the history of the engine, if it was ever rebuilt, etc. I do know that the entire block +...

Well, couple days ago I posted about my issue, today I figured out the problem. I have a 1998 Lexus LX470, 197k miles, the seller I got it from said it needed a new fuel pump and the symptoms it was having made it seem like he was correct. Then after reading up more on it, I saw there was other...

Hi All. This is my first time posting here. I've had my FJ62 for 13 years now. It was and remains my dream car and it's been great to me. Recently, though, I've been having a confusing issue that I would love to get some opinions on. Here's the deal: When I start the engine cold, she runs...

I have a 1994 Toyota 4Runner 3.0 V6 4x4 was running perfect then randomly would start shutting off while driving. Now it starts but has a really bad misfire spitting out black smoke, they remove the O2 sensor just so that it can breathe in case it was a cat issue. Also, I changed FUEL PUMP, the...
