I have two very annoying problems that developed during my recent trip to Le Mans, could be that they are both unrelated but asking if anyone has an idea for either or both.
I recently fitted a 1.8k series eu3 engine with roller barrels and MBE ecu changing from a 1.6k EU2 roadsport carusing the loom from the EU3 engine. Everything has been running well, but on the trip after about 1 hours motorway running it starts to develop a misfire or engine stutter better way to describe it. This clears if you accelerate, but if you try runnning at constant speed the engine starts to stutter. This developed into a constant problem unless accelerating, making driving it quite difficult. Was fortunate enough to find a MG / Rover dealer near Le Man and changed the coil packs, HT leads and Spark plugs. Seemed fine driving around, no stutter or mis fire, until started driving back and the same problem developed. The tick over has also changed it seems to be searching for revs varying from 1000rpm to 1500rpm and feels lumpy.
Second problem is the lights now seem to pulse as do the interior switch lights and brake lights. I changed the alternator over from old engine onto this engine, stupid question are the alternators different.
If anyone has any ideas on these problems very much appreciated.
Thanks
