Hi, I have the good fellow, called santamo, crossfingers!!!!

During last month, when hot, and in very much city driving, start stop, temp normal, and i got the idle go from 900-300-900 rpm, almost stops.

This happens only when very hot, and in city.

I know the mitsubishi DSM ISC valve cleaning, but, in our cars it seems to be again different.

The DSM ISC has plastic cap with 3 cross-screws, and before this 2 screws more to be able to take it out and clear it.

Our has only the 3 cross-screws, on the plastic cap with the 6-pin connector, so how should i disassembly?

Anyone clean it before?

mitsu is http://www.dsmisc.com/dsmweb-d…s/bigpics/P1010004001.jpg

mitsu has 2 rear screws for disassembly.

Hyundai don't have.

Hyundai if i unscrew these 3 screws i will have this

have you ever disassemby it?

cause if you unbolt 3 screws, of plastic black cap, then it is going out, but in pieces.

update...

I didn't unbolt these 3 bolts.

I just cleaned with brake cleaner, the throttle body, very carefully, which looked very clear.

and i didn't pressed brake cleaner through ISC motor, as i didn't wanted to
get in trouble, 1 in a million.

anyway, i installed all back, and idle is very-very stable.

so problem solved.

According to service manual, the 6-pin connector of ISC, must measure the resistance of 4 coils inside. so , in pairs, 1-2, 2-3, 4-5,5-6, and all of them worked at 38 Ohms.

According to manual, these updated ISC value is about 40 Ohms.

So everything good.

I just wanted someone of you to inform me, if he ever opened in parts,

so noone did it.
