P0305 trouble
|
I need some help. I keep having the code p0305 pop up. Missfire on cylinder #5. I have changed all 16 plugs, and even checked the resistant on the coil pack which was .8 ohms on both banks. What else could be causing this? Car runs great still get 20mpg on the highway. Just idles a little rough. Doesnt feel like its lost any power either. Any idea or tips on what to try next or do? Thanks in advance.

Try pulling fuse #11 in the front fuse box and reinstall after about a minute. This will reset your computer and hopefully get rid of the code.

Heres an update. Switched the coil to another spot just to see if the code would move and the code cam back in the same spot. Put some sea foam in the gas and will probably try swapping the injector next.
On another note i did try pulling the #11 fuse and got the same result. I have been reseting it with a code reader.

Of course IF resetting code with a reader and trying fuse #11 and code is still there the problem still exists. NOW IF YOU HAVE AN 2005 R/T, those have spark plug wires and I changed all of our 05 RTs to Taylor shorty wires and my car runs WAY BETTER. If you Hemi is newer than an 05 you DO NOT have spark plug wires. Have you tired GOOGLE for that code and maybe some forum members have had this problem. Best of luck on your search.
I have had a problem for a couple of months now on my 05 RT where I have NO POWER to only the lower portion of the bazel where air conditioning and heat knobs are and have found NO answers yet. Tried pulling EVERY fuse, pulled console to check connections, replaced relays and still nothing, so sometimes the problems are just NOT obvious.

This weekend I'm gonna swap the injector and see if the code follows. I'll update in a few days.

Swaped injectors did a compression test and still have the miss. Took the car to a very trusted mechanic to let him figure it out.

Just an update. The mechanic couldn't find anything today, but from Saturday to today the cyl#5 lost half of its compression. He's pulling the head today to find out more.
