Is the check engine light turned on?
Can you rev the motor above 3500 rpm in any gear other than 1st or 2nd?
About how many miles do you have on the car?
When was the car last tuned up? Do you know what kind of spark plugs were used?
When you replaced the fuel pressure regulator, you used a new vacuum hose? Right? If you just stuck the old one back on, did you inspect it for any problems? Did you check both ends for possible rot under the cloth covering?
So you have a really bad misfire.
And replaced the FPR...
being a 99... when was the last tune-up? Sounds like a spark problem to me. How many miles do you have?
Could be a vacuum line, I'm not sure what all those lines control on a 2.0. Replace those at the exhorbinant fee of $0.80 per foot via your local autoparts store. They're 6 yrs old already, probably brittle and dry rotting.
