SOURCE: PO 1665 code 1998 buick rivera

EVAP is for Evaporative emissions control system, so no this is not EGR, that is Exhaust Gas Recirculation system, as far as the P1665 goes it is related to the other trouble code P0440, u will need to replace the EVAP system Purge flow control solenoid. This should correct both problems after u replace the part disconnect the battery for 5 min's to reset system.

SOURCE: timing spec. 1998 chev 1500 pickup with a 5.7 liter

you need a scan tool to check the timing. You can get close by getting the #1 piston at top dead center, and then dropping the distributor back in, making sure it lines up with the oil pump shaft. then rotate the distributor back and for untill it runs smooth. again this will only get you close. you will still want to have a mech. check with a scan tool.

Codes po 440 and po 530 diagnostic reading does vechile need freon

440 is for the EVAP system.. Leak some where. 530 is for the A/C. This is a circuit problem. Pull the high pressure sensor plug and jump it. If the compressor starts working, replace the sensor. If not check the plug for power and ground. Nothing there. You need to check wiring, the relay, and the fuse.

Service engine lite came on what does po530 and po 440 mean

The 530 code is for the air conditioner and the 440 code is emissions related. Since you did not post the year make and model it is hard to say what to check. BTW the codes are all numbers like p0530.
