Hey everyone so im a little lost, as to my GP is saying that it has a misfire in cylinder 5, but i assumed it was the coil, i was wrong, bought a new one and installed and didnt fix the issue, so i returned it. any ideas as to what would cause this car to work fine until you step on the gas, then it hesitates and sputters, and shudders, then it continues to pick up speed while shuddering. Im really not to sure what may cause this, thanks in advance!

Replace the plugs and wires.

Also check your fuel injector on that cylinder

i was thinking of the plugs and wires next, but the fuel injector is what scares me maybe to, i also dumped some fuel injector cleaner in it to see what may happen (hoax or not; worth a shot) It shudders and just doesnt seem right, can plugs and wires create that?
04-06-2011
Yes they can
Fuel injectors aren't scary at all....in fact there pretty simple.
When was the last time your plugs and wires were changed?

i just got the car in october and i dont know when the last time was

Ok then yeah start with the plugs and wires
Its cheap and doesn't hurt to be done even if it's not the problem
If that doesn't help we will try other things

lol, i just got my misfire figured out recently. i had a plug that kept fouling out fast as hell on that cylinder. turns out it was a coil.
coil- 25
new plug wires- 25
copper core al 605's- 1.99 ea.
the injectors are easy.
depressurize the rails by pushing in on the rail shrader valve, it faces the front of the car
you may need to get a fuel rail disconnect tool from napa, i had rubber fuel lines so i could bend the hoses pull the rails up with out disconnecting the lines
10mm socket with about 5 or 6 inch 3/8 drive extension
four nuts, one on each corner of the LIM and a 14mm on top of the of the SC
pull the little retaining clips off of the injector plugs, 3 in front and 3 in back, with needle nose pliers
pull the rail up and the injectors will come up with it, with the injector retaining clips that hold it on to the rail
remove the injector that goes to the cylinder with the misfire and swap it with another one, just keep note of which one the 'supposed' bad one was swapped with to see if the missfire moved with the injector
you can clean it out with some carb cleaner or some other type of degreaser, and the injector cleaner will also help
put it all back together, fire it up, and scan. you dont have to put the injector plug clips back on yet, just push the plugs on and make sure they are on snug. see if the missfire moved with the injector, if so, bad injector.
hope this helps, just did it about a week ago and dumped a can of seafoam into a full tank to run through the system. my missfire stayed
