stevezetec Posted June 22, 2007 Author Share Posted June 22, 2007 mine is doin exactly the same!, iv disconnetced the idle valve for now.I found when its revving at 2200 that if you put your hand over the airflow meter the revs drop off to normal ! lol strange and annoying.

mc_hurricane Posted June 24, 2007 Share Posted June 24, 2007 forgot to add try disconnecting the airflow meter and see what the results are??yesterday i only just fixed a problem i was having where as when i put my foot down the car would struggle, but if my foot was half way down would accelerate fine...replaced the lamba sensor (diagnosis machine at my dads garage told us too, shows how inaccurate they can be for £7k worth of kit) replaced the tps,leads,disconnected the exhaust,then dad tryed taking the air intake pipe off (including the air temp and air flow sensors ) and it was fine , so put the pipe back on with 1 sensor at a time, air temp sensor is ok, put the air flow on and acceleration sags again so im driving around with the air flow meter/sensor disconnected while i order 1 from somewhere.....sorry bout the life story just so excited i got my "ummmpth" back ....let us know how u get on ?
