2000 Nissan Altima • 100,000 miles

I have a 2000 Altima 2.4. The cars starts and idles nicely in park or neutral. But when shifted into drive its does a hard stall. It will restart but cant get it into drive without a hardstall. The car was in water and some things got wet, like the air filter. I gave it a tune up and replaced the fuel filters and air filter. But the car will not run when placed in gear and it doesnt matter weather its drive or reverse.

Scan for codes and check fuel pressure first
