I did a few searches and didn't see anything which directly addressed this:

My buddy's 02 civic stopped running the other day. He took it to San Francisco (about an hour away) and noticed some sluggish performace under hard acceleration. It got worse as he drove around SF, and found that the problem also occured while making sharper turns (like freeway onramps) at normal speeds, and the problem got worse and worse until eventually the car wouldn't start, but thankfully he made it back home by the time that happened.

So, of course he calls me, I head over and check spark plugs (all of them were firing), his compression (perfect), I smelled for fuel with the plugs out and it was definately there, but I don't check his timing (since he had been running fine for months and the car has only 30k miles on it), everything checks out. Nothing obviously wrong from looking under the hood. I couldn't really look into much else with the limited tool set I had. So, he has AAA tow it to his friend's garage, who's a professional mechanic.

He calls me back 2 days later and says essentially that all they did to get it running was replace the gas in his tank. They told him not to do any hard accelerating, and that he might have "some fuel system problems."

Anybody know what the real problem is? The only other information I can think of is that my boy had his oil changed about a week before this started happening.
