No Power - Need help

[dmltml]

All,

My car is running really rough, sounds like the timing or air fuel is way off. I checked the fuel pressure and it is good. Pulling codes 551, 215. Where is the IMRC? Would this explain the issue? I replaced the ignition coil pack, no change. Help. I need to get to work on Tuesday. It starts fine, no back firing, no stalling, just had a deep sound when I give it gas. I can get to 50 MPH probably but it sounds sick. Any help would be appreciated.

here is a thread about code 215, do you have a spare DIS you can try

IMRC is on the back of the intake, sort of in the center and controls the butterflys If you search for code 551 or IRCM, you can find more information on it. Here is one link

Thank you. I think i will order a DIS asap

The coil pack rarely fails. Grounds are the worst enemy of this electrical system, so I would check the intake to firewall one in particular. Make sure the DIS connectors are not cracked, and that there is sufficient thermal grease on the back of the DIS.

Replaced the DIS and she runs like a beast!
