2009 Toyota Corolla: misfire or rough idle

Filed Feb 8, 2020 · Electrical, Engine · 91,267 miles · TX

My car has 91,414 miles and has had multiple cylinder misfires with my normal daily commute of six miles each way. In three years on a 4 cylinder engine I have had three ignition coils replaced, twice within two and a half years and 10,468 miles on the #2 coil. All repairs have been completed by toyota certified repair facilities with toyota oem parts. This is not normal for a low mileage vehicle maintained with regular service.

Back in january, 2018 my engine would knock when I started the car. Took the car for it's scheduled oil change only to find out that there was only a quart of oil that drained. My oil light never came on. Needless to say the engine continued to consume oil. Took the car to my mechanic and was informed that my engine needed to either be replaced or rebuilt. I opted to have it rebuilt. I paid $4000 dollars for this. Got the car back and drove for a couple of days and checked my oil only to find it was down 1 1/2 quarts of oil after only 2 days of driving on basically a brand new motor. I'm still making payments on my vehicle and have fallen behind several times to make repairs to my vehicle. So far in the two years I've owned this car I've had to replace the fuel pump/filter, water pump x2, front wheel bearings, timing chain tensioner, spark plugs x4. This is getting really expensive. The dealership I purchased the vehicle from refused to even look at the vehicle a week later when I complained about it misfiring.

I bought the car in 2008 and the following january 2009 I noticed burning smell from engine. My dad began checking oil and noticed I was out of oil well before my next oil change. Went to lipton toyota endlessly over period of 6 years and would be told the oil consumption is normal, not a problem. In 2013 they said they found the problem and fixed it. All subsequent oil loss was normal. My engine light started to go on ..coils started misfiring but when I putin the oil it would clear out. Toyota said not connected. They began another oil consumption test in september 2016 and now they are telling me that the engine needs to be fixed. Still saying it's not related to excessive oil consumption.

After filling the gas tank and driving up a hill the check engine light (cel) came on and the engine ran rough. I nursed the car up the hill and drove home. I found the gas cap was not tight even though it had been clicked one time when the tank was filled just a few minutes earlier. A search for this on the internet revealed that others have had this same problem. I tightened it to one click, of course. A few days later I bought a toyota gas cap at a local toyota dealership. This sequence repeated multiple times; cel turned on, engine runs rough, lose of engine power. In one instance I was passing a car on a four lane highway when the engine hesitated and the cel turned on. In another instance I was turning left to go slowly up a steep hill when it happened again. In every instance the gas cap was loose. It happened once when I started the engine in a parking lot. I've come to the point of checking the gas cap to be sure it was tight every time before I start the engine. In early 2015 I bought another new toyota gas cap at a toyota dealer. It's now march 31. This same sequence of events... Cel comes on, engine runs rough, lose of power for about 15 seconds... Has happened about 12 times with this newest gas cap in less than three months. I always tighten the gas cap to the first click as it should be. This can be dangerous if it happens when we need maximum engine power, as in passing. A search on the internet shows that others have had this same problem. Comments on buying new toyota gas caps at amazon show that still others are struggling with this. I can understand fair wear and tear on the "o" ring in the cap. But when two new caps come loose after being clicked as instructed then something is not right. Mechanics at the dealership don't have a good answer for this.

Car would not start, kept cranking, some times would sputter. After 10 minutes or so of repeatedly trying finally it started but sputtered severely for about 30 seconds then rev up normally. Drove to dealer. Had to pay for diagnostic fee of $110 + $10.95 for efi cleaner. Learned symptoms were as stated in tech service bulletin tsb-0182-09 where engine control module (ECM) would cause the engine to misfire terribly. Fix was to have program update and reflash ECM. The efi cleaner added because misfires may foul fuel injectors. Dealer said they would be nice and not charge me for the reflash /update of the ECM. There should have been no charges at all. I hear 8 years warranty on ECM-what does that include, only flash updates and not diagnostic fees? Four recalls and now this. What's next for my 2009 corolla with <14,000 miles and just 7 months out of warranty. Shame on toyota.

Tl* the contact owns a 2009 toyota corolla. While attempting to accelerate from a stop, the vehicle was extremely slow in accelerating and would not pick up speed.
