Minding my own business today doing normal motorway cruise i accelerated to overtake (down a gear) before dropping back to cruise speed only to moments later have a engine/car vibration and a small loss of power (didn't slow the car, just didn't accelerate as it would normally)
. Applying throttle and forcing a gearchange and it smoothed out, as did tipping down a cog manually. Panicing slightly, i limped to the next exit (no warning lights on neither engine managment or gear selection) with it sounding sick, stopped at the top of the slip road with it just keeping running (3/400 rpm) and chugged to a layby. Stopped the engine and aside from a warm car smell everything was perfect (oil, water, belts, hoses, nothing leaking) the ground was steaming under the cats but everything else was a-ok
Now very confused and not fancying a recovery trip i started the car again and..............normal. Perfectly normal. Like a new one normal.
Pulled away with it absolutely fine, did a short experimental run all fine and have driven a further 350miles including many starts, 30mins in traffic, long motorway run and a lovely winding moors road all fine
What when ping, why did it go ping, how did it fix itself from being ping, and will it go ping again!?!? i'm open to ideas!
my only guess is i lost 2 cyls on the coil, it didn't report it because it couldn't be bothered, injected petrol without burning it straight into the cat which then produced the warm smell) and then magically fixed itself.
HELP!
