Coil misfiring? I had to have my car towed 11 days ago and they told me the coil was misfiring and they replaced it. Tonight I drove it and it was doing the same thing! It sounds like crud when its idling and when I slow down it seems like its going to die! Is it the coil again? Will it be under warranty still?

If the code has been a misfire in the same cylinder every time, the problem is very likely the ignition coil for that cylinder. When the ignition coil first starts to go, the malfunctions will be sporadic and therefore difficult to troubleshoot. The ignition coil can be tested for resistance on both primary and secondary windings in the coil to prove it is failing.

was the any oil on the coil boot? you can have a weak injector or a stuck vavle

it could be plugs ,coil pack,a sensor just have to start checking i would try plugs first then go from there if they dont solve it i think it will..

Sounds like either a bad plug or wire, replace both.

faulty coil packs or problem injectors

just be careful i almost set my rx on fire i was told to get a tow to start it all that happened was the unused fuel was pumped it the cat and the whole lot was glowing orange when i stoped the car. the fault was a coil pack it cost me loads to get repaired

when the engine light flashes its telling you the car is miss firing and from your description it was...even though you had coil packs replaced that is by far the most likley cause .if they were genuine parts you will have unlimited milage 2 year warranty.get the fault code read to find out what cylider the misfire was on and change that coil pack..

your vehicle uses a wasted coil pack so two cylinders fail together using that coil so change the coil pack sounds like the favorite to me 3 and 6 are the two cylinders using the same ignition coil

check spark plugs and coil packs
