Yaris/Scion & Vitz :: 2002 Echo Misfire That Goes Away During Idle

Mother in laws car had a bad misfire that goes away during idle. It seems to misfire during take off or slowing to a stop and Intermittently during cruise.

Came in with codes p0300 - random misfire and p0304 misfire cylinder 4

What I have done so far.

-Checked the oil
-Checked the plugs - they were bad so replaced them with ngk plugs
-part number - BKR5EGP

Misfire was showing in cylinder 4 on live data still

-Swapped coil 4 and 1
-Misfire moved to cylinder 1
-Swapped cylinder 1 with 3 to be extra sure and mis stayed on 1
-Swapped back to 4 and even 2 mis stayed in 1. Weird
-Pulled all plugs and checked compression getting 170psi
-Swapped plugs around in case 1 is faulty no luck
-Swapped number 1 and 2 injectors with no change.

So my thoughts now are leaning towards an ecm or a valve thing but would those not be on or off fails? It idles great and cruises great it's only bad we coming to and leaving stop.

Yaris/Scion & Vitz :: 2000 Echo Rough Idle Especially While In Gear And With AC Running

My 2000 Echo (auto) developed a rough idle especially while in gear and with the AC running. It's a pretty rough vibration that seems to come from the left side (belt side) of the motor. When at a stop light with the AC off it is less pronounced.

Last year I had the belts and motor mounts replaced. Well let me rephrase.. I paid to have them replaced, not sure if they actually were. But the car ran great all year until the other day. The belts might be due for a replacement. They sometimes squeal in the morning as I accelerate from a stopped position while running the defrost. Also there is no CEL.

Yaris/Scion & Vitz :: 2001 Echo Cold Start / Car Seems To Idle Rough At Stops

I've been having trouble getting my 2001 toyotoa echo to start in the cold weather and STAY Idling. All I can do to keep the car going is hold my foot on the gas until it warms up, then it stays running, low idle, but running. It starts fine the rest of the day, but that first start in the morning doesn't take. The check engine light comes on and stays on, and the car seems to idle rough at stops.

At first the Mechanic I took it to (good guys) cleaned out my throttle body (physically and chemically) and this seemed to solve the problem for a couple weeks. I'm located in Toronto, Canada, and we're heading into cold weather and I just want a car that starts. It started up again recently and I'm now being told (on my second visit to the mechanic) that it's my throttle body/idle control and that this part needs to be replaced, to the tune of 627.00 + labour.

Yaris/Scion & Vitz :: 2002 Toyota Echo - P0171 Code Thrown While Idle

I have a 2002 Toyota Echo. I just purchases a Creader V code scanner. My car is throwing a P0171 code. The light only comes on at idle or while going under 10 mph.

The data from the reader was:
Trouble Code: P0171
Fuel System sta B1 : CL, using HO2S
Calculated Load: 11.76%
Coolant Temp 188.59 degrees

The Freeze frame data was:
ST Fuel B1: -3.91%
LF Fuel B1: 36.7%
Engine speed: 795.5 RPM
Vehicle speed: 0 mph
Intake Air Temp: 82.4 degrees.

I went back today and ran live feed on the O2 sensors. I'm not sure what STF of O2S: STF means. That was another figure displayed on my code scanner.

The O2S S1 was reading between .04 and about .82. The graph looked pretty normal (I guess) in regards to going up and back down between 0 and 1. I don't know alot about mechanics, but I seen a youtube video of a graph showing it going up and down and what is normal. Mine did that on S1.

O2S S1: STF was: 3.89 and -1.57%

O2S: S2 was a different story. It was between like .58 and .66.

The O2S S2: STF didn't give me a value at all. It just said " --% ". The graph of this was slowly going up but in a small range. It started at like maybe .4 and would go up to say .5. The next wave would be like .45 to .55, then .50 to .60, then .58 to .66 etc. So it was not ranging just between 0 and 1. It had a very tight range that gradually increased upwards.

I built my own smoke machine before testing with the code scanner and I didn't get any smoke coming out of the car except for around the air filter housing where the lid meets the bottom portion. I don't know if it's because I had the air filter wrapped in plastic wrap. Can I have an air leak where the filter cartridge connects that would case a lean code P0171? Maybe I should go try to smoke test again. I did it about 3 weeks ago and I can't recall exactly where I had the smoke going into. I thought I disconnected the PVC hose from the brake booster and plugged it in there. I assume the smoke would get thru the whole system. It took about 2 min before the smoke came out of the filter housing.

The car only sets a lean code at idle or going less than 10mph and I'm coasting in a residential area.

I have an inspection coming up in May and need to get this thing fixed before that. I can't find any other air leak, but I wasn't sure a leak around the filter would cause this and I'm not sure the leak wasn't caused by the plastic wrap.

I'm thinking my only other prob could be fuel related. Fuel filter, fuel pump, clogged injector, or can my O2 sensor be bad and causing this? I've already replaced all spark plugs and coils as well as the PVC valve and cleaned the MAF sensor with the appropriate spray.

The car runs ok. The exhaust seems to smell RICH. Like Gas. I don't think my fuel economy is as good as it use to be. It has dropped from as hi as 42 mpg to between 38 and 40 if I'm lucky.

Back when I was having problems before and realized I had a bad coil, I had tried some injector cleaner. Why the codes were back then, but I had erased them and the car ran fine for about 2 months and the light came back.

My MAF sensor was .14 lbs when I was watching the live data above. I plugged my fuel pressure tester directly into the fuel line coming from the fuel tank and got a reading of between 42 and 44 lbs (car not running, just by trying to turn the engine over). I don't know if that is as accurate (or useful) as having the fuel pressure tester on the car and in line to allow the car to start up and run and watch the tester. I have to wait until my part comes do run the test that way.

Yaris/Scion & Vitz :: Echo 2003 - Check Engine Light But No Code

Recently changed a front pipe manifold on my Echo 2003 4doors Five spd.

Noise I was reporting ealier thread seems to have subsided somehow but I did not hit the high road again, since the repair.

But I have this check engine light that went off 3 days ago and stays on.

Tried 4 times to read the code of OBd II reader and it pulls nothing. As if everything was normal.

I changed the batteries but it acts like it does regularly and it shows like there is no code to pull out.

Could that be a Ghostly Check Engine. It is still on at the moment meaning every time I drive the car.

Yaris/Scion & Vitz :: 2003 Echo Running Rough At Low Speed - Engine Light Blinks At Acceleration

My car is a standard and was working fine not indication of any troubles. Stopped and pumped $20 gas. Started to drive and car starts running rough especially at low speeds. Going up hill is brutal. Engine light flash when trying to accelerate, slow getting up to speed, shudders- not a lot of power, once up to speed engine light turn off.

Press the gas to go up hill- engine light comes back on and it begins all over, it also sounds like it is not running on all cylinders.

Is there any suggestions: fuel pump, fuel injection...spark plugs and wires? Something more serious

Yaris/Scion & Vitz :: 2002 Echo Misfire And Lose Power When Accelerating

Driving on friday night, started to hear at idle the car rpms wavering. Drove home fine with no issues other than at idle. Then Sunday, drove the vehicle, and sometimes had issues when accelerating, seemed to misfire and lose power. Then when driving that day it died completely and wouldn't start. It turns, but no firing.

Got it towed to my place, ran the codes, showed 1300, 1305, 1310, and 1315. All to do with ignition coils. Did a quick spark check, and no spark at any cylinders. I figured it would be weird that all 4 would go at the same time, so i replaced the ECM instead. Still no spark. Where to go next? Also the car does have an immobilizer in it...that could be causing it to malfunction?

Yaris/Scion & Vitz :: 2005 Echo Misfire Intermittently - Cannot Drive Out Of Driveway Without A Sputter

2005 Echo auto 120,000 km

I have intermittent misfiring (a few seconds every couple minutes) and get the codes 301 and sometimes 304/300. I cant drive out of my driveway without a sputter and when I turn into a parking spot or make a quick stop the problem is magnified. I initially suspected a wiring / coil issue but here are my results:

Shuffled coil packs. (1/2 & 3/4)
Shuffled fuel injectors.
Good compression.
Swapped ECM.
Inspected wiring harness.
Goof EFI / cutoff relays.

None of these led to any change in the codes (300, 301, 304)

Yesterday I swapped the fuel pump and it worked flawlessly for an hour of city driving (first time in two months) ... then the issue returned as before.

Yaris/Scion & Vitz :: Echo - Vibration Or Rattle While Idle In Drive

I have taken this problem to the dealer 3 times in the last 6 months and they claim not to notice any vibration or rattle. However, whenever I am at a stop sign or stop light with the car in Drive (automatic trans), a loud vibration sound can be heard and also felt in the steering column and the brake pedal. As soon as I press on the gas pedal again, the vibration goes away. The only other way to stop the noise is to place the car into Neutral. What might be causing this? Apparently, the noise is not audible outside of the vehicle since none of the techs at Toyota were able to hear a rattle or vibration.

Yaris/Scion & Vitz :: 2002 Echo Dying At Idle / Sometimes Restarts

My Echo died on me this morning and would not restart. I was at a light at the time. I pushed it aside, waited a bit and it restarted. I made it to work and it died again after several hiccups along the way. It then died in my parking spot but would restart. It has 192k miles on it.

It was acting weird earlier this week in that it would lose power (not electricity) while moving and then continue on. It seemed to work if I gave it more throttle. I feel like its fuel related but I don't have a lot of spare money to guess at the problem unsuccessfully.

Yaris/Scion & Vitz :: 2001 Echo Engine Light Came On / Code P1349

My great 2001 Echo is acting up for the first time in 11yrs!.. This weekend I decided to have my mechanic change the manual transmission fluid and do a general inspection of the vehicle. He found nothing wrong. I decided that before embarking on a long trip, that I would change the oil/filter, flush the radiator and put new antifreeze, change the airfilter, replace the alternator belt, added a small bottle of Lucas complete fuel system and a new battery.

I was proud of my DIY performance except that the next day the engine light came on! I took it to AutoZone where I purchase all the supplies and battery and they came up with CODE P1349 which I researched and found out about VVT(variable valve timing) malfunction. Some of the reasons for this malfunction are: low fuel pressure due to clogged or bad injectors..... Fuel pump regulator....camshaft malfunction or ECU (engine control unit) problem.

1.This morning the light was off then ten or fifteen minutes later it went on and at the same time the iddle got much faster for about two or three minutes, (in other words the engine was running faster even when I took my foot off the accelerator) and then came back to normal.

2. Later on the light was off again followed by the same sequence of events. Then at one point later I could tell that the the engine was running fast again for a couple of minutes.

Yaris/Scion & Vitz :: 2003 - Echo Won't Start

My wife's 2003 Echo is sitting at 255 000 KM's (Canada) and has hardly had a days problem.However yesterday tried starting and completely dead-not battery as almost new. Ignition makes clicking noise-lights/radio etc all working.Called the BCAA ( Vancouver) the guy tapped with a pole on something in the engine and voila she started. He said something about the starter or starter solenoid-today again the car is dead. Will take it to the mechanic on Monday but how do I get it started meanwhile ? what did the BCAA guy do and what did he tap on ?

Yaris/Scion & Vitz :: 2001 Echo Coupe With Excessive Vibration At Idle And When Running

My 01 Echo coupe vibrates at idle and when running. I changed all mounts, with OEM ones,,,changed the bent cross-member, installed new rack and pinion, new bushings, terminal, bushings...and still the lil guy vibrates like a rattle snake tail.

I noticed that time chain is a bit slacked... what may be the culprit for that vibration, you can feel the vibs at gas pedal, dash and steering wheel.

Yaris/Scion & Vitz :: 2000 Echo Check Engine Light On / Code P0171

First owner, 192000 miles. Check engine light came on during last winter, I put fuel injector cleaner with gas and it went away for a while. It came back on, if i reset, I can drive for about 50 miles before it comes back on line. Also, may be two or three times a week, when moving after a stop, the vehicle stalls, i have to take the feet of the gas pedal and give gas again.

I called up the dealer asking for fuel filter and fuel injector parts prices. Fuel filter is in the gas tank and not meant to be replaced. The fuel injector I was told 4 x $155 each. For diagnostics they need $100

See attached, I was able to clean sensor 1. I could not unscrew sensor 2, the screw is rusted, plus there is no room to get a longer screw driver and turn.

Yaris/Scion & Vitz :: 2001 Echo Faulty ECT Sensor - Error Code P0125

I'm getting error P0125 on my 2001 Echo, which points to possibly a faulty ECT sensor.

Where is this sensor located? Seems like under the air box? Is replacing this part as annoying as it looks? And, are there any other possible causes for code P0125?

In case it's related, I will mention that code P0171 (mixture too lean, I believe) is present as well, and the car does hesitate upon initial acceleration when standing still. Once it's moving, it works fine.

Maybe it's time to start thinking about replacing this car... it has 216,000 miles...

Yaris/Scion & Vitz :: Misfire On Cylinder 3 - Car Hesitate In Reverse And Drive Only

Okay, the code I am getting is a "Misfire on Cylinder 3" code. The car hesitates in REVERSE and DRIVE only, not in neutral.

This is what I have already done: checked all wiring (fixed a bare wire), did an ignition coil swap (#3 to #2) to see if it was actually the coil (no change), replaced all the spark plugs (no change), replaced the MAF sensor (no change).

A shop I tok it to said it was the ignition coil, and that all the spark plugs needed to be replaced. They did not know that I already replaced all the plugs and, having already done the swap with another coil (and getting no change), I find it hard to believe anything they say.

I am leaning toward an O2 sensor issue or a fuel filter issue (but these cars are supposed to have lifetime fuel filters and that is not a job I ant to do if I don't have to).

I was also told that the "green thing" in this photo might be bad. What that is and/or why it would be bad. it does move a little, but so do all the others.

Yaris/Scion & Vitz :: 2003 Automatic Echo Won't Start

I have a 2003 automatic Echo, 200 000KM. I was on the highway with the A/C ON and i suddenly noticed it started blowing warm air(because it was a hot day). I was a bit on a rush so i decided to just roll down the windows and keep on. Once i was on a red light, i noticed i could hear a sound, coming from the straps(wich seemed logic to me since the A/C stopped) The sound was a kind of continuous screeching. It also smelled a liitle bit like burnt plastic or rubber. So i stopped the car, check under the hood, saw nothing, so I decided to start it again. After like 50m, it stopped by itself, and now i can't start it. I even tried to jump start it with a buddy's car and nothing changed! I still have some battery, everything works, but the starter wont even "click" when i engage it...
