okay, its a 93 Si with about 153,000 miles, and a F22B. It was running great until a few months ago. Above 1,000rpm it still runs fine and pulls like anything into the red. Sometimes if i let it just idle on its own, it just stalls with no warning. When it does not stall, it seems as if it stalls for a second then cranks back up and the idle fluctuates below 1,000 rpm. Then when i crank up the car is has NO idle and is rough. it idles similar to how it did when the #4 rod broke. It does burn oil now, but the gas mileage is still about 27 mpg overall and about 30 highway. Any ideas? After Christmas I am taking it to the honda place to have them figure it out if i cant get it......
