Okay... I've got this '90 Legacy named Blubaru.... mainly because we already had one named Emeril... Emeril Legacy.... (BAM!).... and couldn't come up with any other name. And he's blue.

So old Blue was developing a miss on the hills and the check engine light would come on... coded O2 Sensor. So last week I changed the sensor and the light went out. But the miss is still there. Here are the details.....

Starts easy and runs nearly perfect while cold. After an hour or so, once the car gets good and hot, (not overheating), it begins a subtle miss while going up hill or during aggressive accelerations. This gets worse over the next half hour or so, until it barely wants to climb any hill faster than 35 or 40 mph and you can forget about jumping out into traffic! If you park the car for a little while and let it cool down, it runs good again until it heats back up. The check engine light does not come on.

What is the consensus on the next thing we should change out or test? We are determined to fix this car without taking it to a mechanic!

Thanks!
Mike

Does this link sound like what's happening to you?

If it's not fuel related, the pesky coolant temp sensor may be suspect. About $20 for a new one, super easy to replace.
