Hi team,

Seeking assistance, facing intermittent high idling issue. Normally it idles at 700 to 800 rpm. Sometimes after a long drive the idle tends to go up to 1500 rpm. I figured it was a sticking accelerator cable so I pressed and depressed the accelerator cable a few times to no avail. Switching off the aircond brought the rpm to about 1200. Switch car off and crank it again it idles ok. Due to this intermittent in nature every visit to the mechanic was an unfruitful one .

Replaced:
Fuel divider and air flow sensor - used
Fuel pump and filter - new
Fuel Valves.- new
Beru HT cables - new
Plugs - new

Seeking advice where else can i look at to fix this issue.

Thanking you.
