Engine Performance problem
2001 Vauxhall Corsa 4 cyl Two Wheel Drive Manual 7500 miles
The problem comes when the engine is under normal operating temperature. What happens is the engine will stall when it is brought above 2000 RPM's. The engine will idle fine when it is at a cold start. Recently, when the added stress of the a/c compressor was added to the engine when the a/c was turned on, the engine started to die when it was at an idle from a cold start. But, when the a/c is off, it idles fine. The problem only comes when the engine is not at normal operating temperature. The car can be driven when not hot, but, what needs to be done is letting the clutch out, trying to keep the idle between 1500 and 2000 RPM and not stressing the engine over much. If it drops below 1500 and you need to push the engine to bring it up to speed, the car stalls. If the car stalls on an uphill climb, it is very difficult to get it moving again. The engine stress makes the engine stall as soon as you press the gas and begin to let the clutch out. After the car is at normal operating temperature for more than 10 minutes it will run just fine under any circumstances. It runs wonderfully after that point. The only thing I know I know for sure that occurs after the 2000 RPM mark is hit is that the turbo charger kicks on. I would go to a diagnostic clinic, but, I'm in West Africa and that kind of equipment is very difficult, if not impossible, to find here. Any idea of what changes occur after the car is at normal operating temperature that would cause a change in the engines performance? Any idea's would be greatly appreciated. I can do almost all work on the car myself, I just don't know where to look for this particular problem. Thank you for your assistance. By the way, the engine is a 1.7 L Turbo Charged Diesel.
have the same problem?
