Datalog the car and test fuel pressure. Could be a ton of things. Are you not getting a CEL?
This is a discussion on Problems =( Car dying, no power, bogs. within the General Maintenance, Troubleshooting & Accidents. forums, part of the Tech & Modifying & General Repairs category; So I'm driving home from work and notice the car lose all power and has a hard time passing 2.5k ...
So I'm driving home from work and notice the car lose all power and has a hard time passing 2.5k RPMs.
Then it dies on me. Sit in a parking lot for a sec and check everything out, oil fine, coolant fine.
Start it again, idles fine. Goes around the parking lot fine, but when I take it on the streets same thing happens, cant rev past 3k, loss of power, dies. More gas I give it the worst it seems to be.
Sit at a lot for a little bit longer, for stuff to cool down. Took surface streets home. .5 miles away from home car loses power and dies. Had a hard time starting and keeping it idle. Sit in middle lane for 1 minutes. Car starts and I limp to a parking lot. Stay there for about 15 minutes and drive home. No problem boosts fine. But I know this isn't the last of my problem.
Can anyone explain my problem?

I'm looking at a particular component to be the problem, but want to head opinions first. Thanks.

Could be anything from a bad oil pump to a bad tps. It could really be a lot of things man.

That's just what I suggest from my experiences. I'm sure you guys have similar suggestions for him.
I'm leaning towards clogged downpipe. 146k miles on it. My uppipe was clogged last year. And the second downstream cat was slightly smoking. Could it have caused all of this? With work I have been taking lots of short trips lately and with my mileage...
Thanks a lot guys.

I'd honestly check fuel filter first. Start simple. They are known to get clogged, especially at high mileage. It may allow adequate fuel pressure to pass through at cruise around a parking lot, but once you start giving it more gas, it just might not be able to do it.

I'll double check, I actually changed and relocated my fuel filter... 6k ago-ish.
Thing is that doesn't explain my inability to keep the revs up in a lower gear. Whatevers I'll check it out anyways. Thanks Mikie. Man I really wish I had a wideband right now...
And as of this morning, it drives just fine. Fuel economy is crap...ier than usual.
I'm also thinking my MAF is going bad. Learned A/F is has been interesting as of late.
