Rough Idle/Acceleration

[tylers97SHO]

Alright, last night I was driving around quite a bit. When I got in to start my car one time, it started fine but was running really rough, almost shaking the car. It then sounded really rough while I was accelerating, almost like it was missing cylinders. It did that for the rest of the night and again this morning. While looking at the engine while it is running, you can see it physically shaking quite a bit. Any ideas???

I did have the car throw a code with the "insufficient flow to EGR" quite a while ago. I have since replaced the DPFE valve and checked for clogs in my EGR passage. I have found nothing and I don't even know if this is related but I thought I would include it. Let me know what you think!!!

if you can see it shaking, chances are its a misfire and probably a coil pack, but i would get it scanned to see what cylinder(s) its on

Coil pack most likely. You'll probably have to keep driving until it throws a code.

Alright, maybe this will help. I went and got the codes read and I am getting a P0305 - Cylinder 5 Misfire. So if it is the coil pack, can you tell me which one it is so I can replace it? I am not very good at this whole fixing cars thing so lots of help and/or pictures are greatly appreciated! Please please please.

Also, it read a P0401 - EGR Insufficient Flow AND an P0402 EGR Flow Excessive. Any ideas on that? Again, detailed explanations and "how-to's" are greatly appreciated. You guys rock!! Thanks!

Search the other two codes and you should come up with a fix.

As for cylinder 5:

1st in front row

Firewall
1234
5678

well usually if you get an EGR flow insufficient its just the passage is clogged up and you can clean it, but if both of those are coming up then it could be the actually EGR vavle itself

I sincerely hope it is a coil pack. My P-0305 was a lot worse.


Of course you should only experience this kind of damage from a little to much oxygen in that cylinder.
