massive power loss. I'll be as descriptive as i can with the prooblem.
99 Astra 2.0 SRi X20XEV engine.
Car has trouble starting is the first problem, coughs and then struggles to idle but levels out eventually. Now when the car is moving there is very little torque low down in revs. 1st gear pulls with a it less power than it should but hard to notice, 2nd gear feels like theres nothing there, takes an age to get through the rev range and theres no powerband, if you half throttle and let it crawl up the revs i can feel random power bursts for less than a second, feels like its trying to go but something stopping it, its like that through the rest of the gears. 0-60 rough time is about 14 - 15 seconds. The car is standard apart from an egr blank plate and an back box. The egr blank plate was put on as i thought that was the cause of the problem. Does anyone know what it could be.
Things i've checked so far are:
AIRBOX (removed the restrictive pipes)
Car was fully serviced when i bought it 3 weeks ago and oil level is still fine.
I'm at my wits end and its making me not want to drive the car, if anyone knows what it is can you give a rough guide on how to sort the problem.
Thanks in advance
