When my cousin gave me his father's 2000 Toyota Camry LE on May 23, 2018. I bought what the owners manual said to get. I bought NGK Sparks Plugs, Wires, and Coils. The mechanic put on the Spark plugs and wires but the mechanic wouldn't put on the new coils. I still to this day don't know why. The old spark plugs that came out of the 4 cylinder engine had only been changed once. One of the spark plugs ceramic was cracked. I can't believe my cousin was driving the Camry that way. I do some of the repairs myself because I don't trust mechanics where I live. The Camry needs alot of work. It's a challenge that I want to do. Like this video thank much.

if ur ride doesnt run smoother after new ignition parts, give the computer a few miles to learn the new parts, a lot of times computers in vehicles adapt to conditions n have to relearn new ones, u can reset the computer so it learns them faster, but most ppl dont have access to that n it figures it out on its own anyway so....jus give it a few miles, i just dealt with this exact thing on a 99 dodge 1500 5.9, it took about a week n it slowly ran better n smoother

Great video. Just installed a 3.9 L Range Rover V8 into my 1983 Land Rover Defender. Motor was running rich, you can smell the fuel, also seems to be missfiring with low fuel efficency and also low torque for a V8. Will check the plugs, coils and wires! Also running hot, will check that as well

I’m not popping any codes, but my 2001 Accord EX Coupe that I bought for $600 18 months ago runs really rich. It just went over 131K, and now I’m wondering if the plug and coils have ever been changed. Think I’ll be doing some inspecting and probably ordering new ones from 1A Auto. I’m an actual customer and have received no compensation for my endorsement, and I have purchased parts for most of my current and former vehicles from 1A, including an new alternator for the aforementioned Accord. It works perfectly, and the price was about 1/3 that of an OEM.

I’ve seen people test which cylinder is gone bad by removing the coil pack and/or the spark plug while the engine is running (to test for decreased engine performance). My issue is, the air filter is in the way. Can i remove it while the car is running?

I have this same problem. Check engine light is on rough idle it goes up hill fine but you really have to mash on the throttle very heavily. I can't figure out what the problem is ,. You have any idea what could be wrong. It does have broken motor mounts but I don't think that is the problem. The hose or intake pipe , rubber hose that goes to the top of the motor. You have the box that has the air filter enclosure. Hook or clamped to the air inlet that goes into the manifold part ,. It had a tear in the part to the clamp onto the not the box but up by the motor. I took it off to duct tape the ripped piece, but, the whole thing ripped off. So I removed the house clamps and remove the rubber part out it back on , and clamped it down , now the check engine light is on. It wasn't before any help would be appreciated. Thanks

i always was told blinking check engine light means more than one trouble code.i have also learned to believe on my own it means usualky more than one usually but means the car isnt getting enough piwer to function properly.from 1 or a combination of issues that wether together or alone means the car isnt making power.often a misfire for whatever reason ..which is true?

If your car's checking engine light flashes 5 times then stops AND no code reported after you've turned on the ignition BUT not starting/driving the car, that's a different scenario. In this case, the car's computer is trying to tell you that you need to do a drive cycle (see the car's manual), so that the computer can collect data on the emission system to monitor!

However the mass airflow, Throttle body, alternator, compressor, intake manifold are all disconnected from the engine. The first electrician said it's the faulty electric installation, and the 2nd electrician said it's the ECU module. Truth is the engine cranks but won't start. I am having a nightmare.
