High Idle when hot - low power on up hill
#1
Hello everybody I'm new here...
Have this problem with my Suzuki Vitara 97' - any help will be very appreciated...
I live in Israel so its a pretty hot weather here...
When I start my car the idle jumps to around 1500 - when I am pushing the gas pedal the RPM jumps even higher and not going down even when the engine is hot... As I want to start to drive - I changing the gear from "P" mode to "D" the RPM goes down - seems that the gear connection with the engine stopping it from being higher... So it drops to around 1000 RPM..
When I disconnect the ISC electronic connection the idle is drop down - BUT sometimes it may be around the 800 RMP and sometimes its return to be high again..

Well I checked the engine for air leaks - no leaks...
So today I cleaned the ISC - I noticed when I blow into the coolant liquid hoses there is no air flow... is it suppose to be like that or something is stuck there ?

Is this the problem of the high idle ?

What can be the reason of the low power on up hill ?
