i wasnt satisfied with my idle because it idles at 1500 to 2000 so i called up a friend and helped me out.. we tested the tps and it was fine .. and then we tested the BAC valve and it read 12.6 to 12.8 so thats bad so went to the junkyard and got one.. and it read 11.4.. so now i put that on it still didnt work... we check the BAC agen after that it read 12.7 so its bad agen.. so we check the solenoid it was bad as well so i change both of them the BAC and then the solenoid as well... after that it got worst.. my idle is goin up and down and it sound kinda weird we tried timing it but as we move the crank angle sensor it gets worst.

yesterday we fix the BAC and the solenoid and then my idle got worst now its 2k
