Vehicles with delco ECM have a common issue where the fuel injectors leak into the cylinder causing engine to loose compression. The lowered compression causes hard start (if able to start at all) and if and when it starts the vehicle emits a cloud of white smoke for several minutes. When vehicle is in drive the engine idles hunts constantly. Engine stalls while driving making braking and steering very difficult and dangerous. Ecm has been replaced but unfortunately the damage is done to the engine and needs a rebuild. Multiple vehicles have reported this issue from 2009 - 2013 toyota corolla ranging from 100 miles - 179,000 miles. It doesn't seem to have any different effect with mileage or maintenance.

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.

While traveling nw on hwy 99 through merced ca at 08:30 am nov. 9, 2014, I experienced a sudden acceleration of my car while in cruise mode going up the ramp just at the nw edge of merced. It continued to accelerate till the RPM gauge was into the red. At the same time, I was very tense, maneuvering in traffic while applying the brakes in an effort to slow down or stop, which heated up until they were barely working. I shut the motor off while in drive and turned it back on a few times and each time the engine went right into high rev mode again. I finally put the transmission into n and shut the engine off and coasted to the side of the road about a mile or so from where the problem started, regained my composure and allowed the car to sit a few minutes. I tried the engine starter and things seemed normal again so I cautiously exited the highway about a 1/4 mile from where I had stopped. Things continued to act normally so I came back home 18 miles and had no more problems. What do I do with this car? Keep driving it this way? Take it back to toyota? They did the recall repair for this problem already, yet now this!! Very troubling!

I was driving back home and slowed down with the intention of stopping at a traffic intersection. My brakes did not engage at the normal level of pressure that I use, and I had to press it all the way down. When the brake was slammed all the way down the brakes did engage, but the engine started revving up and the RPM meter was to its maximum. I did not take my foot off the brakes because I knew if I did, the car would have travelled at 120mph. I immediately pulled the handbrake lever up, changed the gear to park, and switched off the ignition. I am just happy to be alive today, and am very thankful for my presence of mind. I immediately called a tow truck and towed the car to the nearest toyota dealership. We did take the car to the dealership a week back to do a software upgrade and a couple of other recalls, and the unintended acceleration that I experienced happened a week after that. Toyota after their investigation concluded that the brake and the accelerator were engaged at the same time. They are essentially saying that my 5.5 shoe size foot was both on the brake and the accelerator pedal at the same time. I did look at my foot to make sure that it was indeed on the brakes when the car was revving up. So I can say with 100% certainty that my foot was only on the brake and the brake pedal was slammed all the way down. Like in previous cases e.g. Oklahoma court case, toyota is blaming the driver when in fact, the software responsible for throttle control was clearly shown to have over 85000 bugs by expert testimony given in the oklahoma case. If not for my presence of mind, I would certainly have been dead yesterday, and I am still in shock and awe recovering from the incident.

01/02/2014 at 7:15am: vehicle idled normally for approx 15 minutes while I cleared snow from driveway. I entered vehicle, put my foot on the brake and shifted into reverse. Accelerator suddenly went to full throttle. I managed to shift back into park and the engine RPM increased to red-line level. I shut off the ignition and the engine stopped. I re-started the vehicle a minute later and everything seemed to be fine. I checked the floor mat which was not close to the accelerator pedal. At least 4" away. My foot never depressed the pedal. I am a mechanical designer and I am convinced that this was not a mechanical issue. I never experienced any accelerator issues previous to this event. I am scheduling an appointment with my local dealer to look into this.

Gas intake pipe cracked so warning light shows on dash. Toyota won't fix as past the three years from date we bought it, wonder if a fire could happen?
