Had the car 10 years . My wife ran it very low on petrol . .Filled it at a good friends garage so fuel is OK , ran it 3 miles and then it sat for three days unused . She then drove it 16 miles round trip to work where it started to run on three cyl. I discovered it ran it another 5 miles and then after changing the oil decided to remove plugs to check . No 1 plug seized in and wouldn't budge other 3 ( Iridium ) plugs came out and were perfect . Put it back together , started it and it went down to running on two cylinders . I checked the timing marks on cam and crank pulley , perfect , pulled the three good plugs out and still had compression on No1 . Checked compression on nos 2,3 and 4 all at 220psi . All four leads giving good spark , pulse getting to injectors ( checked by adapting side light bulb, a neat trick ) . Chenged nos 3&4 injectors for nos 1&2 and engine still fired on 3 &4 . Cam cover removed and cams seem OK .
It's in a local garage now and even he is baffled .
MLS gasket fitted 5 years ago , engine was running perfectly , no water loss or any other HG symptom .
Is there any scenario that would cause injection system to shut down nos 1&2 cylinders under a fault condition ?
I've left the Haynes manual in the car so can't check but is there a crank or cam sensor ? and what would symptoms be if Lambda sensor failed?
Your help would be appreciated as this is puzzling .
