It took a while of terrible running to get check engine light. I rented a code reader after seeing I have good fuel pressure. Here are the codes
P0171 (lean-bank 1)
p0300 rand-multipal misfire
p0301 cyl1 misfire

now I cleared codes and ran it-still just bogs and miss's over 1500 rpm, but check eng light doesnt go on- I could probably get it to go on if I beat the crap outa it, but it sounds pretty bad and I feel with the info I provided one of you can tell me where to go from here.

Hello,

Ok, when was last tune-up?

On the Lean Mix code check for Vacuum Leaks at intake manifold leak, leaky vacuum hose, leaky EGR valve, leaky throttle gasket or low fuel pressure (weak fuel pump or bad pressure regulator).

On the Misfire codes could just need a tune-up. Depending when last one was done. Would inspect plugs, wires, Cap & rotor if equiped and Coil.
