*New Here* I am in some TROUBLE! 2004 Mazda 6i - Mazda 6 Forums : Mazda 6 Forum / Mazda Atenza Forum

Hi guys, im Corey and new to the forum. A lot of good info here but nothing that can help me answer my question, so here is the scoop.

12/22/12 around 2:30pm went to the car wash, washed the car and decided to pop the hood and do the same ( all with a pressure washer ) also kept the car running the whole time and didn't spend much time under the hood with the water. Everything was fine when I got in the car and took off but about 1/2 mile down the road I got a horrible misfire, drove home about 8-10 miles away and plugged in the OBD2 scanner. 2 codes - p0301 ( I believe ) Cylinder 1 Misfire and a second one pending. Checked all the plugs they all had oil on them, cleaned em off and changed all the coil plugs. Still, getting a horrible misfire. its sat since about 4pm up until now which is 8 hours later and still a horrible misfire but now its even worse.... Upon heavy acceleration it falls on its face and jerks bad! also the Speedometer is going crazy jumping up and down on its own. I checked to see if cylinder 1 is getting spark and it is, hmmmm... I am lost!! I am shocked that is gotten worse and not better, not trying to drive it much don't wanna mess it up... here are the specs on the car ---

2004 Mazda 6i (4Cyl)
5 Spd
144k Miles ( No service lights til now )

If anyone has any idea, experienced this problem or could lead me in the right direction I would greatly appreciate it!

Thanks,
Corey

PS. Forgot to mention that I moved all the plugs around ( they all had a good amount of oil on them ) and still cylinder 1 misfire..

Also checked MAF sensor and it was dry..

I am so lost

I wouldn't quote me on it but I've always been told not I spray wash your engine especially if its on because it can short circuit electrical components.

Washing the engine with a pressure washer is fine. Your issue is you did it while the engine was hot & while running. Two big no-no's. you also want to try avoid electronic areas like the ignition coils. Spraying water on a hot engine can cause cracked/warped heads/block as well. Lesson learned i hope....

Try taking the ignition coils and moving them around to see if the misfire follows. You may have toasted one or more coil. Also spray some wd-40 or contact cleaner on all the connectors & pins between coil packs & wires to get rid of any possible moisture in there.

If you have spark then the next thing causing missfire can be fuel related. Maybe the injector is not operating as it should. I would assume that you do not have a mechanical issue on the engine internals based on how it all went down.

Just because he has spark doesnt mean the coil pack is functioning properly. It could be shorting out even if it seems that its sparking like it should.

I would say just a shitty wet coil. Ive done all of the above with no issues.

hcokiid · 12-23-2012, 12:55 PM

Ok so the misfire is now gone thank god but now I have a new issue. Car was running great for 5 minutes then it cuts out and rpm drop to 0 and the red key comes on the dash then it goes back to working perfect. Did that about 3 times. I'm hoping its just wet still and will be completely healed later.

Mr.Smoke · 12-23-2012, 01:00 PM

You likely just have some moisture on connections still. Everything should be ok once it dries up.
