I have a 2001 Ka with 1.3 Endura engine. I cannot get it to run properly. Symptoms = starts and idles fine but soon as I take off it loses power and sounds like it's running on 2 or 3 cylinders. Very occasionally it runs OK for a few seconds. No fault codes showing. I have taken it to a local mechanic who has all the diagnostics gear and he says ignition and fuel pressure fine. Good even compression ..valve clearances checked. Exhaust analysis indicates it's running lean. I've replaced plugs, leads and coilpack (aftermarket). Checked hoses and filters. Also had injectors checked and cleaned..perfect. Have tried different ICV, throttle body, O2 sensor and throttle position sensor.. .... no change. Mechanic has named it the devil Ka because he cannot explain why it won't run properly. The car has done 101k and is in very good condition so I think worth (within reason) sorting but cannot believe how difficult it is to fix it.
Mechanic thinks maybe ECU itself is faulty? I have some questions around the ECU and would appreciate some feedback from those in the know....
Can I get ECU tested to see if it is operating as it should?
As an alternative can I get another ECU from a car wrecker and slot that in without any drama? Is the ECU standard across all Endura powered Kas?
Do I have to get new key and transponder to make the replacement ECU work in my Ka?
Any other suggestions about how I can get the bas***d running 100% would be very welcome.
