I seafoamed my 04 MCS today. Put about 1/2 can into the pvc line and let sit for about 20 mins. Only a little bit of smoke came out but it won't idle. It just dies/stalls if I dont give it any gas.
I also reset the ecu at the same time.

Did I use too much seafoam? How can I resolve this?

 

I would drive it on the highway for a good 30 Minutes or so, that should clean everything out. It will take the ECU a few cycles to get everything smooth, I would not have reset it while you were doing the seafoam, but it should fix itself with some driving.

 

Thankyou.

Everything is running good again

Removed the vacuum line and got the crankcase some fresh air. That really helped it out. Now it's back to normal.
