Monte/Mike i need your help plz

[DXB_Tuner]

Strange! many fault codes appeared when i scaned (121, 0300, 420, 430 and 513) and the engine is not working well. I did clear all the codes, but a missfire code always showing up and the engine is not running 8 cylinder. am having 07 Escalid EXT and am using U7194, v9.r07. Do you have any doubt, I need your help plz..

For your information, i removed the cataly and switched off COT.

If your getting a consistent misfire code....then you probably actually have a missfire.

i feel that the rear 02 sensor which i switched them off been damaged and caused this problem!!

Id restore the stock tune and see if it still happens.

i did restore the stock tune, but still the same..i took my car to the dealer and am waiting for their report..

[pheonix311]

well, i dont see how a damaged 02 sensor could cause a misfire in more than 1 tune.....im interested in what the dealer says

yeah, if it's still doing all that on the original stock backup, then it's not a tune issue... definitely a problem with the vehicle...

Finally, i've got the report from the dealer and thank god it was an injector fault. One of the injectors went off and the dealer replaced it and the engine now is running smoothly...I'll plug in the predator and install the tune, so am back to business guys..thank you all for your concern...
