Hi Shantel


 


After I replied to you earlier today I noted that you have taken two payments from my credit card, both of £ 13.00 on 24/03/14. A total of £26.00.


 


When I logged onto your site when I put in e-mail: [email protected] it was rejected so I put [email protected] which was accepted. I then aked one question and gave payment details once.


 


Please refund the £13.00 that you have taken in error.


 


I await my answer.

Hi Greg


 


It is a 2006 Mazda MX5 2.0i Sport.


 


Engine is LF type, number 772520; it has not been modified and the exhaust system is also standard. Routine servicing is up to date.


 


There is a little instability whilst idling but it drives normally.

Hi Bob ..

So many things can trip this this code as it is reporting the engine is running to lean .
Possible cause for this to happen .

Vacuum leak , check here first with you having a slight uneven idle
Leakage at the exhaust.
Rear O2 sensor failure .
IAC and ECT malfunction .
Front A/F sensor malfunction .
MAF sensor malfunction maybe dirty ,clean with MAF cleaner .clear code recheck.
Fuel pump pressure ,test pressure .
Ignition system ,timing out .
PCM malfunction .

Do what you can like with the vacuum leaks exhaust leaks etc
If the engine has over 100.000miles replace the front and rear sensor
but this mat not be the fix the sensor should be changed at this mileage.and where diagnostic tools are needed you wil have to use a good shop .

Need further assistance then please get back to me .


My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back with the reply box below and not the poor or bad service button ,
For further assistance there is no extra charge after accepting.
