Anyone here a mechanic part 2

[Becoming]

Got my codes read.... here is what they were....

P0351-Ignition Coil A Primary/Secondary Circuit Malfunction

P0303-Cylinder 3 misfire detected

P0304-Cylinder 4 misfire detected

Now I did NOT reset the light before getting it read (though I changed plugs, plug wires, oil, trans fluid, filters etc - btw I did not do this as a kneejerk- but because my wife takes godawful care of her ride)

So I suppose I should reset it tonight, and then get it read again if/when the light comes back on.....

I would also think that the Ignition Coil Circuit Malfunction could be causing the other codes to occur?

So how should I attack this if the light comes back on? (which I assume it will considering it is still running a little rough, BTW it runs real rough when I start it... but smoothes out a lot after goosing it.... but still rougher than it should be....)

I know I have lots of green to be dished out for the last thread.... Same applies for this one- helpful advice will be rewarded....

well certainly sounds like an ignition problem. do all the wires in the ignition system seem intact? like are any of them melted causing a short somewhere. did you replace the distibutor cap and rotor if it has one (do newer cars still have these?) Perhaps it fell out of timing can you check it with a timing light, are all the plug wires correct, is it possible cylinder 3 and 4 plug wires are crossed, i've done this before when replacing plug wires.

new wires, no distrib (EFI), plug wires are in right place. light came on before replacing plug wires....

It's your radio. Get a new one.

Buy a new car.

Can't help you on this one. Might have to take it in to the dealer or your repair shop.

Wish I could help.

my guess......
timing is off

i would take it to a good shop, should be able take care of it, counting that nothing is damages from running the oil dry, fried piston ring, no damage to ignition



just my guess though

here is what I have found out so far....

Found this link...

Here are the causes for P0351 reading....

* Open or short in Ignition START/RUN circuit
* Open coil driver circuit in harness
* Coil driver circuit shorted to ground
* Damaged coil
* Damaged PCM
* Coil driver circuit shorted to PWR

So I guess if it is not the coil pack I got to check the wiring after that....

Two people with the same car said they thought it was the coil pack.... One of them had the exact same thing happen, the same codes came up and basically he had to replace his engine coil pack and all was good...

I assume the coil pack is the black box with the six holes and the plug (where the plug wires come out of....)

how quick is this to pull out/put in (anything I have to be careful for?) can I take the old one into autozone and have them check it to be sure that was it.....?

I have checked some prices around here...

Autozone has a Wells for 63.97
PepBoys has a BWD for 69.99
Checker has a Niehoff for 87.99
Cheker also has a GP Sorensen for 132.99

can I just pick the cheapest- or any of these are bad?

I was really afraid of this SES light/code thing before, but now I am seeing how awesome modern technology can be!
