The next thing on what seems like an ever expanding list of things that need fixing on my LCR is the slightly rough idle. Basically the revs stay constant apart from every now and then (around every 30 seconds) the revs will fall for a split second and the engine seems to struggle for half a second before returning to where they should until it happens again.
I have done a bit of searching around at the usual causes and so far i have had it in the garage to check for vacuum leaks which they fitted a blanking plate for the secondary air filter that had been removed and called it fixed (not sure if they checked all the other hoses etc)
i also sprayed some electrical contact cleaner into the MAF sensor through the mesh (i didnt have the right tool too take the actual sensor out of the housing) As well as cleaning the throttle body by spraying a load of egr/air intake cleaner and wiping with a micro fibre cloth which someone pressed the accelerator so it was open.
Since doing all of this i'm sure sometimes when i first start my car and drive off in the morning it hesitates slightly, but only right at the start, its fine after a minute or so.
Does anyone have any suggestions as to what could be causing this? if its required i can try and capture this on video but i hope i have explained it well enough!
Im thinking something along the lines of getting it booked into a garage for a proper smoke test to see if there are any vacuum leaks or possibly buying a new MAF sensor?
