Changed the spark plugs, swapped out the first coil pack, no change, put the new coil pack in the second spot and the second one in the first spot, no change, Just did the EGR valve because there was no vacuum in the lines @ 2000 RPM. Not getting the flashing check engine light now, but still misfiring and just got these codes. Can anyone tell me what to do next?

The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms

My 1999 lexus es300 is still reading the codes P0300, P0302,P0303 after giving it a tune up.


Your codes indicate misfires. What was done in the "tune up"? Misfires can be caused by any of several different causes including (but not limited to):
spark plugs
spark plug wires
coil packs
injectors
injector wires

The term "tune up" used to mean, "replace points, condenser, distributor cap and rotor, and plugs". Since most cars no longer have points, condenser, distributor cap and rotor, we need to ask what was done...
