hi people, can anyone help? My Esprit has decided to invent its own random cruise control. Start the car from cold, no probs, warm up in driveway, no probs, drive it around at a legal pace, no probs, but if the red mist should decend and you give it some beans then it decides to idle at 3000 rpm. On the road you dont have to touch the throttle to maintain 50mph Come to rest and it drops to 2500rpm. It does eventualy come down but its no happy. The back ground to this that the engine has been out and had, new timing belts, alternator, air con pump, all turbo hoses, two dump valves, plugs, and anything else that was about to brake. The first thing that goes through the mind is what have i left off/connected wrong, but i've been over everything i can think of and have found no probs. It seems strange to me that it only occurs when you give it some helmet? No fault codes present. Does a proper lotus diagnostic computer go into the system any deeper than the EOBD that I can get into. Any advice would be great and probably stop me reaching for a box of matches.
