Two problems related to cruise control have been reported for the 1999 Mitsubishi Eclipse. The most recently reported issues are listed below.
Since the first month I have owned the car, the car frequently idles low (~500rpm) when the weather is warm. Car has no power and will sometimes stall when I remove my foot from the gas. Car has a 5sp manual transmission. Has been into the dealer 14 times for the same failure without resolution. Typically, they reset the "curb idle" which results in the engine check light coming on 15 miles down the road. The dealership has also replaced the iac motor and the mfi relay. Last time, they adjusted the tps switch and the base idle. The failure still persists.
The vehicle does not stay set on high speeds. If cruise control is set for 80mph the vehicle will drop down 5 or 10 mph less without warning. Dealer says it's made so that driver can't drive at high speeds.
