Toyota - Sequoia :: Ignition Coils Keep Going Bad
Aug 6, 2015
What would cause me to have to replace several of the same ignition coils in less than two years time? It seems like it always happens after I purchase gas.

View 1 RepliesI just had the ignition switch replaced on my 2001 Toyota Sequioa. Now my blinkers work but will not shut off after I complete the turn. Additionally, the blinker "stick" is very hard to move in either direction. I plan to take my car back to the dealer and politely request this blinker repair be warranty work.
View 1 RepliesI have a 2002 Toyota Sequoia, V8 4.7L that overheats only when the A/C is turned on. Without A/C on, it runs perfectly normal. I have replaced the thermostat twice, replaced the radiator, replaced the electric A/C cooling fan, replaced the fan clutch, and just recently replaced the water pump (wow, what a job that was!). Even with all these repairs, the engine still overheats only with the A/C on. What to do next?!
View 3 RepliesWe have a 2008 Toyota Sequoia with 60k miles. We purchased 100k mile warranty when we bought the car new. The past year or so, the car will stall just after starting. There is no rhyme or reason as to when it will do it (hot, cold, morning, day, night, etc.). It will stall after starting and won't start after several attempts. You wait approximately 10 minutes and it will start just fine. This happens about 2x monthly, sometimes more sometimes less. Toyota has no idea what it is, they tried cleaning up the carbon buildup.
View 2 RepliesI have 2 spark plugs not firing. one of the three ignition coils does not fire, the other two do, is the most likely culprit be the ignition control module? car has the 3.8 motor.
View 4 RepliesI haven't had a check-engine light yet, but at idle, my 1996 Maxima has a sporadic misfire -- there's no rhythm to it at all. Does this sound like a symptom of a coil going bad? What would be a good way to test them without having to replace all 6 of them? The car has about 175,000 miles on it. I just put in a new set of NGK iridium plugs, and hope I didn't damage any wiring in the process (that doesn't seem likely, but I guess I can't eliminate that possibility).
View 16 RepliesMy husband's 2001 Buick LeSabre had an ignition module and one ignition coil replaced in March. Yesterday, the car broke down, and the mechanic told us that the new ignition coil shorted out the other two coils. Is this believable? We've been using the same mechanic for several years because we trusted him and have heard a lot of good things about him, but this seems kinda fishy. This car is not one of the GM cars that was recalled.
View 10 RepliesI have a 63 dodge pickup with a habit of burning out ignition coils within 2 weeks. It's happened with the slant 6 motor, it's happened with the 318 v8 and its also happened with the current motor a 440. I have changed the ballast resistor, and the ignition switch, as well as the starter solenoid, and all related wiring.
View 4 RepliesSo the previous owner of my V10 Ex had all the plugs changed and some of the coils needed to be changed at the same time.
Some have a yellow sticker on them. Some are plain black. The yellow ones say "Motorcraft" plainly on them.
The black ones look identical to the ones on my wife's Duratec 3.0L V6 in our Mazda MPV. They also have a Motorcraft part number on them.
Vehicle is a 2005 Toyota Sequoia SR5. Door locks cycle on and off. Happens during wet weather and usually takes 2-3 hours of driving. Sounds like there is a relay shorting out so that even though the doors are already locked, it attempts to relock them. If I unlock doors using the rocker switch, immediately locks them.
Then the lock mechanism tries to lock them again, and cycles through this every 10 seconds to 3-4 minutes randomly. Is there a relay under the hood which might do this when moisture enters the engine compartment? If so, where is it located and what is the part number.
One mechanic suggested that I replace the multiples computer located in the rear tailgate but he wasn't very clear about why he thought that was the case.
I was driving in 4wd this weekend and when I tried to get out of 4wd the center light won't go out. My truck also won't turn "tight " turns like its "stuck". How do I get this light to go out? We tried what the owners manual said and it didn't work.Will this hurt the truck to drive it like this????
View 1 RepliesI have a 2001 Toyota Sequoia that started having problems with the intermittent setting on the wipers. It is now to the point that it runs just like the slow wiper setting with no delay, it also doesn't "park" the wipers when turned off. I found that with the ignition in ACC position the wipers work perfectly (intermittent works and wiper "parks" properly when turned off) but when the engine is running I only have a Low or High wiper speed and no "Parking". I have researched online and most say to replace switch or wiper motor but both work with engine off so I am wandering if it is being overpowered with the engine running.
View 4 Replies2001 toyota sequoia had oil changed but the oil leak out within 1/2 a mile. Engine automatically shut off. Oil was refilled but when we tried starting it, it would not run. The engine would crank over and over but would not get to the point where it would run or start. Ive been told there may be a safety shut off unit that activates when there is very low oil or no oil at all. What may have actually happened? Can a motor seize within a few minutes of driving @ 40 mph?
View 11 RepliesI have 06 XLS with 56,000 miles and about 3 weeks ago the check engine and VSC lights came on. It was fixed, a ignition coil on the 4 cylinder.
Now driving home today the check engine and VSC lights are on again! I was wondering should try to get the dealer to replace all the remaining ignition coils ?
Plus I read their was some type of manufacturer defect on the original ignition coils from the factory. Why Toyota won't recognize this issue ?
Two ignition coils in a little over a month . My first Toyota and I'm rolling with the punches .
what's causes the "vsc/trac" warning light and "vsc off" indicator light come on and off, together with the "brake" warning light while i'm driving?
View 4 RepliesMy wife has a 2007 Toyota Sequoia with only 17,000 miles on it (as of Mar 2013). It has had regular scheduled maintenance - engine oil changes, etc. However, due to low mileage, it has never had Transmission or Radiator fluid changed. All miles have been in town, short trips. Is there a need to have these fluids changed just due to the age of the Sequoia and type of miles driven. It is an expense I would rather not do unless necessary. We do plan on keeping it to well past 100,000 miles. Considering the age and miles, is there anything else that I should be watchful for or take action on?
View 13 RepliesI have honda civic 2005 Lx with 170,000 miles. I noticed increased RPM about 1.5 with cold start but no missfire. I attempted to take out ignition coils to see if genuine ones solve the issue. It is very little rainy today with high humidity. After I put new ignition coils, I noticed increased shaking with misfire. I have not touched anything except for putting in/out coils. I ensured the position and connection of the coils. Is this anything with humidity? I did it really quick without much exposure to the rain. How to resolve this issue? at least return to previous condition?
View 7 Replies2001 Toyota Sequoia LTD, 115,000 miles, replaced cal & discs & steering rack bushings early last year. Lately after 20 to 30 minutes of hwy at 70mph touching the brakes to shave off 10 to 15mph causes heavy vibrations from the front brakes like the wheels aren't round. No lights, ABS or VSC, no noise from the ABS unit. Same in 2WD, 4WD, VSC on or off. Touch the brakes from 70mph and it feels like slowing/stopping on washboard??? Tech checked, no codes present . Brakes function fine around town as does the ABS & VSC, alignment good.
View 1 RepliesI recently noticed louder than normal road noise coming from he front end of my SUV, which is right at 150K miles. I thought it was bad tires; both front ones had uneven wear. Got new ones and the noise is still there, loudest at 35-45 mph. The tire guys said I need new tie rod ends. From what little I know about those, they don't make the kind of noise I'm getting, but what do I know. I do know they are safety hazard and plan to get them fixed pronto. But will that fix the noise? I had the left side wheel bearings replaced last year, but this sound is not the same as this. Much less pronounced, but still fairly bothersome.
View 8 RepliesI need to know what the resistance should be on my 2002 Echo's coils. I have an intermittent sputtering problem and it's driving me nuts! I put E3 spark plugs in the car about a year ago to improve the power and economy (it was on the original plugs at 160k miles!!) and they did work a lot but not long after that the sputtering problem started.
The car does have a code for the pre-converter O2 sensor but I replaced it, cleared the code and it keeps coming back. I have not pulled the codes recently but will in the next few days.
I've also read that the fuel filter is inside the gas tank but there is an access port under the back seat. I doubt that would cause the intermittent problem but I could be wrong.
I have a 2000 f150 with 198,000 miles. The lite on the dash came on, "service engine soon" , I had the codes read and they said the coils are going bad.
