I popped this code several times this weekend. While the light was on the car doesn't want to start as easily. After the car is started it seems to run fine. I checked for fuel in the vacuum line and found nothing. I cleared the code and it would stay off. After more driving (with some hard pulls) everything seemed fine. The light was still off and the car was running good. Once I stopped and turned the car off, the light would appear when I restarted it.
P0190, but sensor and car seem fine

im assuming that code is fuel rail pressure sensor... have you checked the pressure?
well its throwing a code for either too much or to little fuel pressure. i would suggest starting by checking your pressure. do you have a preadator or any scanning tool that you can see live data tables? you can even borrow somebody elses predator to run a scan with.
you may have to use a serial cable and a laptop. i know its very easy with a predator. i personally have a predator just for logging my car(its married to an other car, but i dont use it to tune)
you could always go to a parts store and rent a fuel pressure gauge and see if the car is close to 40psi. the problem is you are reading actual pressure and not delta pressure (difference between rail pressure and intake manifold pressure).
find a way to get fuel pressure and report back your findings and we can go from there. there is no way anybody can really diagnose your car from behind a computer without more knowledge of the situation.
I'd just keep an eye on the FRPS.
I am having the exact same problem to, exactly and i put a kennebell disc on back in November. Car runs fine, but the code comes on when I hammer it. I just ordered a new FRPS from tousley, I hope it solves the problem.
yep code here but vac line is fuel free and car runs fine except for the other day which is what brought me to this thread. Any updates??
