Hi all,
At my wits end! The idle speed on my 940 will not drop below 1100 rpm. Have tried all the usual stuff, changed IAC, TPS , ECT,,and carried all the adjustments out as per the manual and the tickover speed still doesn,t drop to the magic 750 as required! When driving up to lights or whatever it will drop to @ 1400 and when you take your foot off the brake then it will drop again to @ 1100. Occasionally but very rarely, it does stay at 750 and then when you drive off and stop again its back at 1100. Its got the Bosch LH 4 injection by the way! If anyone can help I will be eternally grateful to them!! HELP !
