hi im running a 1997 ibiza 1.4 sxe (aex engine) having a few problems with the throttle at idle and when changing up heres the symptoms:
start up seems ok but in idle when its given a little blip of throttle the engine seems to go down by about 100rpm as if its going to die then it kicks in and revs up,theres a good 2second delay,also under the bonnet when you give it some you can hear a whoosh as air is sucked in but it doesnt seem to want to respond until 2seconds later,theres definately a noticable delay,it only happens from idle and responds instantly if reving from say 2000-3000.theres also a tiny delay when changing up and down until the power comes on,so i have to almost power shift to get rid of it. any help would be greatly appreciated.
this is what ive tried already: complete new ignition parts plugs,HTs,dist cap,rotor,(not coil tho)
Cleaned throttle body bore with carb cleaner,used injector/fuel cleaner in tank,new air fillter,oil and filter change,checked breather and vac hoses
