every time I start the car the oil pressure warning light stays on for about a minute. the oil is full what is causing this

Cats and sensors replaced with Bosal and Denso about 2k miles ago. Code returned recently.

Exhaust is now new from engine to tailpipe.

LTFT at 2K is at 16%. Have smoked it several times, repairing leaks as I find them (leaking EGR to intake gasket, cracked upper resonator tube, cracked intake tube, cracked EGR vacuum control valve vacuum tube).

After repairs, the codes are cleared and we attempt to set readiness, but code returns, and LTFT really doesn't drop.

Only one code appears. I have the graphs of the o2 sensors (a/f sensor) as well as freeze frame screen shots, but I am not sure how to post them.

I'm replacing gas filter and would like to correct procedure.

I saw on the 2000 Impala it did, so does the 03 have one too? I can tap my hazard light switch and the blinkers will work one time or maybe 20 times, and then it stops again.

The lights, radio, dashboard lights and everything come on fine. But I have to rev my car while turning it on or it turns right off. Problem happened this morning when I tried to leave for work. All my fluid levels are fine. Please help .
