Conway's biggest headache in the mid-race stint was Oriol Servia, who was never far off the rear of the #27 and seemingly in much better shape on the tyres. Conway pinned his hopes on a switch to the harder black wall tyres for the final third of the afternoon.
"Things picked up a bit on the last set of tyres, I was able to drive hard and was passing people," he said. But the pit stop had cost him still more positions and he was now down in 16th place, although he was able to start carrying out his plan to charge back through the field with a quick pass on Takuma Sato for 15th.
However a late full course caution for Sato subsequently crashing out closed up the field and left Conway battling for position with Conquest's Sebastian Saaverda going into the final lap, and the two clashed.
"On the final lap, I tried the outside of turn two but Saavedra made contact with me which knocked me off the track and punctured my tyre," explained Conway. Saavedra meanwhile was sent spinning out onto a steep dirt incline off track and disappeared in a cloud of dust. "That was the day ended. Not a good finish for us."
That left Conway limping home in 17th place, a disappointing outcome given qualifying although he was still a lap ahead of two of his team mates, Marco and Danica. Ryan Hunter-Reay had a more solid race and just gatecrashed the top ten by the chequered flag.
Conway - who turned 28 in the interval between New Hampshire and Infineon - was quick to put the whole California event out of his mind and look forward to the next opportunity to make his mark, this weekend's maiden street course event on the east coast of the US.
"We now head to Baltimore for the first time," he said, hoping that the fact no one in the field had any experience on the streets of Baltimore would give him a genuine chance of success on a level playing field. "I visited the track a couple of weeks ago and it looked great so I'm looking forward to racing there for the first time next weekend."
In a generally uneven year for Andretti Autosport - with Indianapolis qualifying proving a particularly low point for the team and for Conway in particular, who failed to make it onto the grid - there have still been some memorable highs, with Conway himself taking his series début win at Long Beach, Marco Andretti triumphing at Iowa and Ryan Hunter-Reay retaining that controversial victory at New Hampshire two weeks ago.
Conway will be hoping that Baltimore is one of the 'up' events for him and for the team as a whole. In the meantime, the start of the week saw him return to the reality of real life with a bump, as he tweeted: "Rainy day in Miami! Renewing my drivers license ... so slow!! Feels like Sonoma 5 laps in ... would rather be sliding around than this though!"
Lifestyles of the rich and famous, indeed.
