What order to do timing, tps, iac??
Since changing the timing will affect idle rpm, how should I go about precisely tuning the car? It's a tpi iroc lb9. Should I do IAC and TPS then timing or the other way around? It just seems like adjusting the timing can change the rpm which will make me want to reset min. air which will make me want to reset the tps...you get the picture. Thanks for any info...

Ok, did the timing change your idle rpm? I have my IAC and tps set right and I'm just messing with timing - the manual that came with the light says that timing changes can affect rpm so it seems like we're dealing with a loop of cause&effect. Thanks for the reply.
