i keep getting a code 332 after i replaced the egr pressure sensor and cleared the computer. what else is there? engine is running a little lean. any suggestions?

O2 sensors and the MAF can also cause a lean condition, as can a clogged fuel filter. Can you give us more info about the truck (motor, mileage, etc.)?

I see you have a 94, if it's got the 4.0 check the lower intake manifold bolts. They are bad about loosening up and causing a lean condition. They will also cause it to use some oil. Check your vacuum lines to make sure none of them are cracked, especially the one going to the vapor collection canister.
