I notice the mild roughness to the engine when it is cold. I have no problem with this since it is better than the 30 seconds of really rough idle that could stall, and you aren't suppose to push it until the oil temp reachs 140.
: We I start driving my car from cold start up, running 40mph in 4th gear, it feels like the engine is surging or missing. It's very,very mild and goes away once the temp gage reaches mid range. I've had the upgrade on the DME for throttle response when cold, but not the rough idle. It did this before that was done. Anyone else have this?
