checked all hoses visually and all seems fine, noticed car seems ruff on idle now as well with rev fluctuations, if the car has went into limp home mode, do i need to reset the ecu to get back out or is it automatic

i belive that you need a code reader to erase any codes to get it out of limp mode?

ide turn the car on and try listne out for any boost leaks too (might be hard over engine noise)

bad idling will be a leak somewhere, pulling in un-metered air

I may be wrong but I think limp mode goes off when you turn the car off. Obviously if whatever caused it happens again once you start her up again then it will go back into limp mode until switched off again. I was switching the car off and starting it up again whilst moving when I had the problem with mine.

didnt think it was too hard tbh,on start up its ruff then idles for a while and then goes ruff again, , its actually cutting out now, have checked the ignition amplifier, seems ok, but my experience with them is limited lol
