If i drive the car with the ECU just laying on the floor in front of the battery it always drives perfectly, but as soon as i try to tidy it away, i have tried beside the battery, on top of the battery, above the glove pocket and tied to the heater pipes then i get an assorted mix of intermittent misfires, coughs and cutting out, i have managed a couple of times to pull over quickly and lift the bonnet, the left hand manifold feels colder that the right one, this is just by hand.
i have pulled back the cable coverings to check the cables, they all look good externally.
Any ideas?

My floor is dry, but wasnt when i bought the car last year, the ECU certainly has external signs of corrosion,
I have opened up the plug and all cables and pins look very good, the plug holds in place very well.
I have thought about trying another ECU but the price for a TVR one is very high, but i see a Land Rover one is much less, my chip is removable and i am happy to swap it over, is there anything i need to check if i buy a Land Rover one?, i see there are some other numbers apart from 14 CUX.
The other option is a break inside a cable, not so easy to find.

When I first started testing this I put the ECU away I then covered it all in with the carpet section in front of the battery, the car ran really badly, but intermittently all day, I removed the front cover thinking it was overheating, it seemed a bit better, but still not perfect until I laid it on the floor
Others following me mentioned that they could smell petrol while it was misfiring, so I don't know if the injectors are switching off or on too much.
So any ideas of how to actually narrow the possibilities down would be grateful, I don't have access to another ECU unless I buy one

I had the ECU open last year QBee, you loaned me your ECU which I was going to try until I found 2 pins out of position on my chip, I know that the internals look ok.
How does the lack of signal to the injectors give the smell of fuel?, but yes loosing a signal makes more sense than firing too much, I guess I can hook up an LED to the output of both, or would voltage displays show more?

If we assume that a break in the cable is more likely than a short, then what would be the reaction to a loss of signal from the Lambda sensor?
I do have Rovergauge if someone could advise on what to look for, the fault can appear very quickly after starting, less than 1/2 mile sometimes

I think having the ecu tested will not necessarily show anything as most of the time, at least 95% everything works perfectly, i have stripped the connector cover off and checked all the pins are fixed correctly, i have removed all the cable wrapping as far back as i could and everything looks to be in good condition along with the various joints.
originally i thought it was heat, but now its tucked up on the roof of the footwell without any covering and still it sometimes plays up within a mile or 2, so dodgy cable / connector does look likely, i guess its going to need continuity testing while i bend all the cables around.
Does anyone have a reliable circuit for a 1995 500?
