Hi, the above vehicle when first started in mornings, the engine hunts when idling and also hesitates when pulling away. The car has been scanned and no fault was shown related to engine electrical system and there are no air leaks on the inlet manifold.
Any idea what the problem can be?
Do you
have the same problem?

Try the in tank stuff first and be patient, it takes time to work. There is also a more intensive professional type that I have used, it requires the purchase of $$ tools and is quite effective. Lets go with the less expensive method first.

Thanks for your reply. I have put a quater of the injection cleaner in with a quarter petrol. I will keep doing this until the bottle finishes and see what happens.

Hi, regards to the fuel injector, the liquid has now been used up. Car seems to improved a bit but still hesitates and hunts at times, even in warm weather. Is there anything else I can try?
Also the speedometer and the computerized mileage in car is now not working. My abs still nedds to be replaced. Is the abs causing this?

Try a different fuel from a Chevron if you have one nearby. As to the speedo being inop, it is related to the ABS issue, fix the DSC and the speedometer will start working again. DSC is dynamic stability control and is tied to the ABS

Hi, one of my keys to the car stopped working. I changed the battery in it and now it can only start the car, I cannot lock/unlock car with key.
I was told that key needs to be programmed, when I do this it swipes out my spare key.
Any idea on how to get both keys working.

You will need to reinitialize both keys. Get in the car, shut the door, put the key in the and turn it on then off then take it out and hold the unlock button and press the lock button 3 times and then let the unlock button go, then the central locking system will lock and unlock all the doors and then you repeat the same process with the second key. Do you understand?

Thank you as usual for your prompt reply. I will try this asap. Only one question, do you turn the car on fully when you put key in and out.

Hi, I have tried several times with both keys as u described. They both do work. However, after the second key is done, the first key seems to be swiped out again. Any other way around this?

There may be a problem with the sequencing. Try disconnecting the battery over night and reinitializing both keys again.
