my brother has a 05 and just got the coils and starter done. Literally the next day he starts it up in the morning and it shakes pretty crazy for 5-8 seconds and goes too normal idling. I guess it did it again when he got off work AND the check engine light came on but the car drives fine. Any ideas guys?

They disconnected the battery to install the starter. The ECU needs a few more drive cycles to re-learn the fuel trims. This is normal.

Did the check engine light remain on? If so, go to Autozone and have it read for free.

Yeah it remained on I'll give you guys the update in the morning when he drives it to work lol

Other than the check engine light it seems normal for when the battery is disconnected.

Dso

Yea he's just kinda freaking out cuZ he just dropped 1200$ on all this and then it does this so I said I'd just ask you guys

$1200 for coils and a starter? Man...... The shaking is likely unrelated but it's a pretty vague description, could be many things.

yea 1200 is absurd. Anyhow, my assumption was the shaking was due to the rough idle. Not enough info to really go on though.

Low compression in rotor 2 :-/

So he spent $1200 before spending the $125 to have a compression test? I hope he is still covered by the 8 year/100k mile core warranty!

Ok but that doesn't happen overnight. Was he driving fine before the ignition was changed? Are you sure the right coils are connected to the right plugs?

Theres also no such CEL that would tell you if you had low compression or not.

Dso

Yeah everything was fine until the starter and ignition coils got replaced. It even drives fine when it actually starts up too. Easy redline no acc problems
