I do have a occasional stumble when just driving along. It looses power completely for a fraction of a second, some time multiple times in a row. When it does once it feels like just hit a dip in the road. Some days (today) it will do to 10 times on way to work, then goes a several days without doing it at all. Talked to one mechanic he thought maybe TPS sensor, I moved the SGII to it this week, watching TPS, GPH, MPA, and instant mpg. GPH goes to 0 or close to when it does it, instant if does it long enough goes 9999, I don't see any changes on the other 2.
Thinking of picking up a fuel pressure gauge to see what the pumps doing. Any idea?
