V8 Disco 2 not running properly

[finbar44]

Hi all,

I need some advice with my disco 2 V8.

It was barley running with about 10% power and would barely drive off the mark and would not speed up at all.

I have changed the MAF sensor with no change.

I have then checked for spark and was missing spark two cylinders each side, this points to a crook coil pack.

I have put on two new coil packs and a new set of 10mm HT Leads.

This has given it more power but it is still not right with lack of power and hesitation.

It is duel fuel but the problem is on both petrol and gas.

Could it be the ECU? or the leads from the ECU to the coils?
Do the ECU's fail?

What else could it be . Please guys help is needed.....

Cheers Ben....

just a thought, check your TPS wire connector under throttle intake, and see if it hasn't broken a wire off at the connector.
V8's use a TPS on the throttle, (TD5s have it built into the accelorator pedal)
cheers, Mario

get someone to hook it up to a nanacom or similar and reset the addaptive values.possibly not needed but won't hurt to read the codes anyway.
is it still missing or just low power.
