hello are you here?
i have corsa 12xep 2008. it has rough idle, or pulsing idle, pulse 1-2 times a second. revs goes up just a little bit, 70-100rmps.can feel car is shaky.
i'm a trader and i can take from good working car any part i need. also have opcom and deplhi and launch machines.
till now i've tried:
map sensor, throttle body, spark plugs, compression test, then took whole intake manifold from another car with all injectors and other bits on intake manifold,tried to remove aux belt, checked timing (with tool) nothing helped. erased all codes , map sensor comes as faulty sometimes and engine light on. but if i erase it it will come just will couple days, or maybe it came back because i unplugged. map sensor tried from 3 corsas, all same with same part number, no luck.
well, i took auxbelt out, feed car with extra battery, and same problem persist, also i unplugged camshaft sensor on rununing car, and it make no difference, im not sure but maybe camshaft takes reading only on start up?
i have already booked to main dealer on thursday.they will charge me a lot for reprogram repair ecu..but if it not helps them ahhhhh.
