does one bad coil affect the performance of the others

No it doesn't. I've replaced a few individually in the past with no performance difference. After have half of them being two different types, I just replaced all 8 of mine with this coil.

NO, but the bad one will affect on the engine performance and turn on the check engine light. I replaced 5 out of 8, but looks I'm gonna replace the rest also.

No. Each cylinder has a coil, it will only misfire on the bad one, unless more than one are bad. I bought one of these to replace a bad, which I couldn't figure out until it got bad enough to throw a code.

Define performance? It does not effect the performance of the other coils but it does effectthe way the engine performs which has an effect on the otherr coils if that helps you any.

What what I've read, no. But, I replaced all of them at once since I was doing my own work and they all were old (12 year old truck). Probably wasn't necessary since the auto-parts store told me which one was bad.

Typically if you see a break in the coil this would indicate the bad one. I would recommend you replace all of them at once.

The coils I bought for my Honda Fit did not work they were defective and I had to have them replaced within a month.

First, change your spark plugs. Then you should read the codes, but they sometimes lie about which cylinder it is. To confirm the bad coil, you can disconnect the coil connector, and drive it. If it drives the same as when it is connected then it is a bad one. This doesn't work too good if more than one is bad.You could just replace all 8 and be done with it.

Briggs & Stratton.......but I think coil wire was a little longer. I didn't need it anyway. My old one was good. Be careful with test procedure.....even Briggs tech line was wrong.

I'm running a stock Bosch coil too. As noted, be careful with the wiring. This distributor is much-much better than the stock. You'll be very happy.

I would check for spark first, a simple test for this would be unscrewing the spark plug while connected the putting the against a piece of metal if you see sparks consistently then the coil is good and it most likely is a fuel delivery problem. This one way work I would mesaure and make sure the screw holes line up otherwise you may need to machine new holes. hope this helps.

If you have a US Fit it should be fine. I would also guess that the coils should work fine with other versions but I can be sure.

This product is packaged to prevent any damage however if the box is compromised in any way the coils will break. Thank you for your question.

I don't think so. It only reads errors that the on-board computer returns. It wouldn't tell you if a coil was shorting, or any other mechanical problems causing a misfire like a bad spark plug or a dirty fuel injector.

Nope. It is better to buy something that is rated higher. In case there is a need of higher power consumption. Besides, it is better to be over-rated then under in such scenario and prevents any of this eletrcial items from burning out.:)

Never has, It will run rough but not on certain cylinders sounds like a coil pack, plugs or wires to me

I wouldn't assume this to be the answer. Could be your distributor, wires, your fuses, your O2 sensors...this rig is notorious sometimes. I did use this injector though, and more efficient fuel delivery is noticeable, especially at lower RPM's. If your injectors are shot; I'd replace them with this; but don't expect it to fix all of your issues at once. Good luck!

It is better to replace both than trying to find out which one is bad. Also if just one has failed the other may fail soon.

If u wrap it around a plug wire, u will get incorrect readings and response, but if u wire to the coil u get no lag

No. All of these coils was damage. Maybe in 2 months all of these parts was fail

Excellent Indoor Air Quality (IAQ) is ALWAYS worth it. Health reasons aside, your indoor coil will stay clean and never require ($) cleaning. It will transfer heat at maximum efficiency also. That lowers energy costs.
