Engine gurus please help! Do i have a miss?

(O) = Key On Engine Off test (KOEO)
(R) = Key On Engine Running test (KOER)
(M) = Memory code



12 Idle Speed Control motor or Air Bypass not controlling idle properly (generally idle too low) - ISC

41 (R) System lean - Fuel control
(M) System was lean for 15 seconds or more (no HO2S switching) - Fuel control


32 EVP - (R) EGR not responding properly during test - EVP

13 (O) ISC did not respond properly (extends to touch throttle then retracts for KOEO) - ISC
(R) Idle Speed Control motor or Air Bypass not controlling idle properly (generally idle too high)
(M) ISC sticking, open ITS circuit or TP sticking

17 1.9L & 2.5L - Throttle stop set too low - IDLE


18 (R) Check base timing & advance function - Timing Tests
(M) Ignition TACH signal erratic - Ignition Systems


Ok so basically, you need to clean or replace the iac, you need to set the idel and add some fuel too because the advanced timing is making it run lean possibly. and if you have a egr valve make sure the position sensor is plugged in because one code said it didnt respond. A more serious problem that shows as code 41 is the possibility of vacuum leaks.

here is an article on how to set idel.
