Today my 986 died on the Bay Bridge

Batteries can do some crazy things to modern cars that depend on a very steady voltage. The speedometer in my S-10 used to warn me when my battery was going south. If the speedometer started bouncing around it meant that I'd better park somewhere good because I was not going to get it to start up again. Corrosion on the terminals of my 944 used to cause complete electrical failure. I'd be cruising down the highway at night and the entire car, headlights, taillights, dash light, engine would all go black. I'd have to coast to a stop then it would fire right back up and work fine for a few more days.

New battery has been called in and is awaiting me for after work today at the local store.

we'll see what this does, then move on to the fuel pressure testing.

Thanks!

So... of course. I changed the battery after autozone tested it, and put in a new one. It now starts and drives, albeit with some loss of power. I'm going to jack it tomorrow and pull a plug and see if I can get a clue as to what's going on...

Update:

Some loss of power is a pretty consistent loss of power in every gear. It drives, but is slower to rev, and on the freeway cannot get past 65 MPH. I've parked it back in the driveway. It's got 92k and the original MAF.... I'm thinking that after looking at all the other high mileage cars on this forum, that could be the culprit?

No codes are being thrown right this moment, and the engine does make a backfiring noise if I gas it too hard to "overcome" the loss of power

BUMP.

Who says MAF is the likely culprit?
