i recently purchased aem ems i have had problems ever since i have in stalled it it will not idel under 1100 rpm every afr is good timing is good iac is good tps is good iam also running a 2 bar map with 450 dsm injectors and a lc1 wide band im thinking that it might be by distributor but i really dont want to waste my money if i dont have to so if you guys have any suggestions please write back thanks

 

wrong forum, but you proabably have a vacuum leak, try idle screw, pcv valve, intake gaskets or your injectorseals are leaking. try the tech forum

 

it ran good before i took my obd2 computer plus vafc out since i didnt need them anymore and i have checked all my wiring on the harness i also wired in a lc1 wide band with a 2 bar gm map everything as far as air fuel and map readings are good but once we turn the idel down to 1100 it just dies aem is just either to in depth or i need a new distributor oh and i took the throttle body of and cleaned it out all that has been taken care of she just wont run right and where do i need to post because their not to many people in aem forum that will reply and aem techs just dont help at all

 

have you checked for sync errors ? or timing errors ?

 

yes i have i get a timing errors also i installed a aftermarket flywheel but there is no mark for the timing adjustment so i marked the block and the balancer at top dead center and adjusted we are dead on the distributor is dead on also there is no adjustment for it because of the three bolt pattern so i no thats right but i was thinking it was the distributor i heard aem dose not like obd2 distributor because of the crank trigger coil

 

i have no pcv i converted over to a catch can for all the blow by also the injectors are new the orings are new no boost leaks cleaned out throttle body and adjusted back and forth iam stumpted iam thinking of leaving the feed back of the iac off or just start getting some answers from aem they have not been staightfoward with me and iam disssatisfied with the tech support but if anyone has any feed back please contact me thanks
