Start Up Sputtering
Only does it when doing the cold start. I let the engine run for 10-15 seconds to return to the optimal temperature so it is no longer running at the cold start rpms. Once i put the car into drive the car slightly sputters for several seconds. Its not enough to be jerky, but enough to make me have some concern. This usually lasts for around 15-30 seconds, half mile or so. It does seem to go away and only do it after the cold starts. Should I put a can of Techron through the system? My car has 40k miles on it.
