New engine fully rebuilt failed m.o.t for emissions! Ran very rich for idle absolutely choking stuff and had a slight misfire.
Eventually tracked it down to an exhaust leak just after mani where the decat pipe connects which caused these unbelievable symptoms.
Now I have a problem very similar to topmansparkie post where the car seems lumpy on idle, seems as though it is going to cut out then revs go up by themselves and seems to clears self for a while..... However under driving the car can seem to be running alright and all of a sudden it seems to be choking as there is no power and the car will not accelerate(hesitation).
Funnily enough the engine prior done exactly the same thing and was my reason for putting a new one in as it was using alot of oil and just put the rough running down to this however it is now evident that this is not the case............
Electrical?????????
I have changed the Maf, plugs leads coil, Coolant temp sensor, cam sensor, lambda(all with new gen parts) and even the small loom that powers icv tps etc.
The ICV got replaced about 18months ago as did the TPS at the same time(again gen ford parts)
Any ideas please!!!!!!!
You will not be shot down in flames......... I just want more theories
