Since my DSM injector install the car seems to stumble on cold start ups, once it is warmed up for a few seconds the car runs as smooth as always. Is this a common issue? Do they need to be cleaned possibly? Running them via hondata by the way so thats not the issue (or so I would think).

 

i have the same problem but i am using the vafc hack.

 

I just put my 450s in yesterday, and I have the same sort of reaction when starting my car. Sounds like a common problem.

 

me too. it's wierd. sometimes it starts with less than one crank, other times it takes more than a few.
