Hi there. Seen a lot of postings on here regarding this, but when hot the idle hunts between 500-900rpm, and occassionally stalls when you lift off. Standard ecu, passes diagnostic. It's running 12-13psi. I'm going to clean the throttle body this weekend when I do the suspension and brakes (busy weekend!), but should I also do the fuel pressure regulator and fuel filter as a matter of course? Can't find out when it was last done before I bought the car, and I have only covered 2500 miles in it. Cheers, thanks for all the continuing good advice!

PS I have a lovely shiny pair of Japanese adjustable upper arms and tension rods looking at me in my hotel room here, just shipped from Courtesy! ;-)

go round giving all the connectors a good clean be surprised what a differance it can make,unfortunatly theres a few things that can cause idle problems but by eliminating them one by one

change fuel filter

clean TPS connector

clean IAA connector

clean MAF connector

throttle bodies
