Is there a way to monitor IAC counts using DIC? Trying to troubleshoot decel stall problem on 99SLS with 71K miles.

Don't think so. Pull your DIC Codes and look for P0300 series....near stall, P0335/6 and P0385/6.....CKP (CranKshaft Position sensor fault).

The ol' TB cleaning bugaboo, also.

I'm not a Tech II operator, but maybe a shop could set one up to monitor IAC function during a drive condition.

Submariner,

Thanks for reply; I do get a stall/near stall code, but no CKP codes. TB was cleaned recently by dealer(problem predates this cleaning). This week I plan to clean TB and IAC passages myself just to be sure, then go down AJ's previously published check list.

Have you tried cleaning the EGR valve? It should set a DTC, but can't hurt to clean it anyway.

I have not; I'll do that too. Thanks
