I today attempted to drive the car for mot, got as far as the petrol station and found the car was running extreemly lean ( 16 on wide band but 16 is as far as it goes!) on part throttle and on light load doesn't pull at all feels very weak I'm assuming this is due to lack of fuel.
It's not misfiring died a Cople of times at idle from cold.
Have now had enough and shipped the car of to a garage (Tsr) to fix an oil leak from the endplate at the cambelt end of the block as it's leaking from where the oil gallery in the end plate meets the block I think it's the rubber tube between the two. I asked them to check mechanical timing and cam timing while there at it.
My main problem now is this running very lean as it's dangerous. Especially as the engines just been rebuilt. I injectors where cleaned and tested, fuel pumps new no leaks, fuel filters new. Chip is ment for my spec. Maybe pressure regulator any one had any problems with theirs. Could it be 51mm throttle body letting in to much air at part and full throttle? Felt very slow when give full throttle hardly moved at all!
