When accelerating on highway check engine light started flashing and engine running rough. Pulled over and stopped vehicle turned off ignition. Restarted vehicle and light was out no longer running rough. Toyota dealer checked computer, cylinder #2 misfired 47 times & cylinder #3 misfired 3 times. They said they could not find what had created this problem and still charged me for engine diagnostics.

Driving down the road and was passing a truck. CEL and TRAC OFF lights came on and truck went into limp mode. Could not accelerate and truck was slowing down. Had to pull over turn truck off and restart and it ran fine until I duplicated the passing and push on the accelerator. Had codes check and was showing misfires on cylinder 3. I changed the spark plugs and checked the coils which were good. Next day was I was driving and truck had the same problems and eventually died and would not restart. I took it to the toyota dealer and they checked numerous things and had found #1 cylinder intake value was leaking. They suggested to replace the entire motor at a cost of $12,000. I declined and took it to another mechanic to see if the head just needed replacing. In that time I found others were having the same problem and it was a malfunctioning part in the intake manifold. https://www.tacomaworld.com/threads/2016-tacoma-in-limp-mode-fixed.659782/ This is the forum were I found the problem and it fixed it. A piece of it was holding my intake valve open and that was the cause of it not starting and the leaking valve. I went and showed the Toyota dealer and they were not aware of that problem. I would like it to get posted so others don't get con into putting a new motor if it has the same problem. It seems everyone that has this issue is around 17 and 18 year models and all ranges of mileage.

Driving vehicle on a side street going approx 20 miles per hour. Car started shaking and lost majority of power. Was able to get car back to residence (only got a couple of blocks away) when heading to destination. Had vehicle towed next day to same dealership who had recently replaced fuel pump under a recall (paperwork for this recall is what was experienced /stalling dangers). Dealership told us not fuel pump but wiring harness needed replacement because rodents ate the wiring ( soy bean covering on newer vehicles )and engine lost power because of this. Thank goodness not on a highway going 75 mph. When this happened as we very well could of been. Told we need to deter these rodents from continuing any more damage. Wonder why company would use a product. Thank you.

On several occasions my car has lost power and started idling very low in traffic. There has been an open recall for several months for this problem and Toyota has not fixed it.

My 6 speed manual V6 3.5L trd off road Tacoma has hesitations and bucks when you apply throttle in the lower RPM 1000 to 2000 range to accelerate and also has poor throttle response when down shifting to slow and make a turn onto a side street. You have to apply almost 3/4 throttle to get the RPM to come to where you can rev match to the appropriate gear. It makes for a jerky ride for passengers and seems hard on the drivetrain. No dealer fix is available. Clutch pedal also squeaks on warmer days.

2018 Tacoma trd sport manual transmission - this has been going on since day 1 - engine hesitation in 1st and most noticeable in second gear. The truck hesitates and surges during light and moderate acceleration - feeling like an extreme lean running condition. This puts the driver and other people around you at risk when pulling out into traffic or highway. If you shift a touch early into second gear the truck occasionally bog ( starve for fuel )heavily - where you must either be patient, slip the clutch press on the accelerator harder, or downshift. The hesitation is there all the time and more noticeable with any load up any incline. This is dangerous and the driver must be prepared at all times to down shift, slip the clutch, and must know about the hesitation. My co-workers and friends have driven with me and can't believe Toyota hasn't fixed it yet. My son came home from driving it - saying its hesitating severely. This has been going on since day 1 and getting worse.

When slowing down before making a left turn across traffic, after the vehicle comes to a crawl or stop and then I accelerate to turn left across traffic, the engine hesitates for 1 to 2 seconds before accelerating. I took my 2018 Toyota Tacoma to my dealer and they were able to replicate the problem. A re-set or upgrade to the computer has not fixed the problem. There is a great deal of discussion of this issue at https://www.tacomaworld.com/threads/3rd-gen-stalling-in-intersection-update.459540/.

There have been several times I have gone out to my Tacoma that I can hear the fuel pump running on it's own. I heard it running one evening, while no keys were inserted and the truck was locked up. The truck runs rough most of the time and I have problems with it stalling and not wanting to start back up again. It will take 3 to 4 times turning the truck over before it will reluctantly will start up. Also the traction control button does not work anymore and the differential button when pushed on does not engage the differential. All of these issues have started at different times. The fuel pump running when no one inside it has just the month been noticed as well as the buttons. The stalling started to be noticed about 4 months ago and I at first thought it was due to it being not broke in or me not giving it enough gas, but it is almost every time now when I back up or go forward it can stall.

Vehicle exhibits a stumbling condition and loss of power when applying heavy throttle to accelerate from a stop or slow vehicle speeds. While driving under moderate throttle at approx. 45-60mph the vehicles engine feels as if it is misfiring and not running on all cylinders with a heavy delay in throttle response when the throttle is applied to increase vehicle speed. Issue has been brought up with multiple Toyota dealerships and also with Toyota Corp customer service. There is a software flash to correct this issue but Toyota refuses to offer it to customer with manual transmissions because their tsb's do not list that manual trans. There is a 145 page forum thread regarding this issue where customers are resorting to flashing their trucks on their own to avoid the dangerous driving condition these trucks are exhibiting. Here is a link to the thread: Https://www.tacomaworld.com/threads/software-update-for-the-manual.562550/ tsb 1 listing condition: Https://toyotatalk.com/wp-content/uploads/2018/07/Tacoma-T-sb-0062-18.pdf tsb 2 listing condition: Https://toyotatalk.com/wp-content/uploads/2018/07/Tacoma-T-sb-0058-18.pdf

2018 Toyota Tacoma I4, when cool or cold engine or transmission will stall & stumble while accelerating you can be smooth or aggressive & it will occur, it has also occurred when it has been very hot outside 85-95 degrees and occurs even at normal engine operating temperature. The transmission also will down shift to 4th gear for no apparent reason while cruising @ 55-65mph on flat and level roads, it also constantly hunts 4 gears. I have been to Toyota dealership several times and the cant duplicate the issue. I have been told by Toyota that because my truck is a (4 cylinder) that they are not as many on the road as the V6's models so Toyota engeneering wont even look into the problems that I have been experiencing. They just say that's normal Toyota performance.

All his happens on and off.

He truck idle speed management under load from cold start is erratic. If I put vehicle into reverse to back out of garage idle speed jumps 200-300 RPM and jerks before settling down. If I turn the steering wheel at creep speed (engine at idle) idle speed jumps 200-300 RPM. I took to dealer 8/7/19 and dealer says no problem found. This only happens when coolant temp is stone cold. It has done this since new.

Vehicle surges when steering wheel is turned, also is hesitant to shift gears on highway. Frustrating as it is difficult to drive efficiently when your car does not shift as expected. Tiring to drive in this way.
