Engine 850: B5234TR/2.3/20v/T5R: - getting the right hump with it now!!!!!

infinity1 · Jan 2nd, 2008, 17:20

right further to my previous posts on the car losing power etc,but only when its warming up,from cold to hot,when its hot it runs fine its just the bit inbetween!!like today dropped the kids off turned engine off,had a cup of tea etc i was away from the car for a max of ten minutes got in and drove off,and within 500yds all power gone,no response from throttle,put the car in nuetral and watched as it vibrated, shuddered,all lights on the dash flashing,coughing trying to stall,then it suddenly rights itself and its like nothing happened,(at the correct temp then!)
i have had a very lenghty discussion with a lambda expert(!) he said that it couldnt be the lambda sensor(or its highly unlikely it is!) so i am really at a loss as to what i could possibly be, new rotor,dis cap,leads plugs(correctly gapped),new coolant sensor,new air filter,all vacum hoses are good, the only thing i havent done is the thermostat but this couldnt really make this problem could it?
any one got any ides at all cause im buggered if i do know now!!!
heres hoping for a miracle!!!!

there are no codes and i have heard pete's engine run, at the time i was unable to give it too much of a going over, but ONLY when cold it sounds like it is running on 4 cylinders, when its warm it runs fine but is a sod to start.....
cheers

im fairly sure pete has a vacuum leak somewhere, tho on inspection it seemed ok, most of the "usual" stuff has been done, i have a feeling its going to be me, pete and my new halfords tool kit, a lakeside a weekend soon....mini-meet anyone...
