Hey there, previously, my car was throwing the Multiple Cylinder Misfire code. Well I changed over the plugs, (the plugs in there were horrible!!!). The car idles much better, and the engine seems smoother. However, after that, my car is now throwing a Misfire in Cylinder 3 code. Should I try switching the coil packs to see if it's the coil pack that is bad(if I'm able to disconnect the plugs...)? My plan tomorrow is to replace the fuel filter. If either of those fail then I'm possibly looking at replacing the fuel injectors, correct? The car does have 171k on it. Is there any good fuel system cleaners that I can buy to try flushing the system out?

Thanks for any help, I'd like to get rid of that stupid light.

Switch the coil packs around, then, check with a hose to see if the injectors are making repetetive noises.

Mine did this last week and it turned out to be a dead coil pack on #6.

So it cost me 71.50 to fix.

 

WOW. A lot of misifire posts in the past week.

I took my car to a shop to have my 2k2 Muffler installed (cut&weld) along with my Budget B Pipe and Magnaflow Resonator. Later that day, my car was running vary rough. I just got a misfire in cylinder #6. I changed all of my spark plugs. Still misfiring. I checked to make sure that there was even sparks coming from the 6th cylinder...and there was. So with that, I ruled out spark plugs and coil packs.

Now, on to the injectors. I switched #2 with #4 (i am calling them #2 and #4 with perspective to the spark plugs) to see if that was the problem. Now I have a multiple cylinder misfire. Also, there is gas leaking in the weld that the shop did on my muffler to make it fit.

I really do not know what to do at this point. I need to *FIND* a place to buy a Noid Light to test my injectors. I also need to get my weld fixed on the muffler. Anyone have any tips?

 

OK, I'm only going to say this once:

IT IS ONE (or perhaps more) OF YOUR COIL PACKS GOING BAD!!! I will put $$ and my life on it!

 

Thanks for all the quick responses!

I will try changing the coil packs around to see if the codes will follow it. Also, looking at the motor from the front, is cylinder # 3 the back middle cylinder or the front middle?

Thanks again!

#3 is back middle
