Had similar on my 90 petrol, would not do much over 30 mph and if you put your foot down hard at any speed it misfired and cut out, turned out to be fuel pump.

Check fuel pressure... my money's on coil pack/leads.

If ok under load when cold then the fuel supply is ok, it sounds like something not liking heat, so I'm going for HT coil or ignition amp module. Badger.

Hi matey, just spoke to the chap, he says it runs mega sweet at idle, once driving on load it 'hiccups' now & again.
Does it hot or cold.
I am off to pick it up week after Easter, i was gonna take a load of stuff with me to bolt on, like coil, leads, fuel pump etc
Any clues from the comprehensive description?

Hmmm... unlikely to be fuel I still reckon, but check for split vacuum hose at rear of plenum to pressure reg, although that would have more of an effect off-load. I'm thinking possibly airflow meter in addition to what I suggested previously? Badger.

Hi, it's an 89 with new head gaskets, known good compression etc
He's done the following...
new airflow meter new leads new plugs dizzy cap rotor arm
not sure of coil
He seems to know what he's doing too, but it's got him stumped. I'm not that arsed, but i will be driving it home & it's 180 miles...
The fuel pumps die on load dont they?

He hasnt tried a new coil on it yet, he's going to try a new one for me. For what they cost, may as well fit one anyway.

if it's a RR 3.5, it's a different pump. I was takling about the ones in the 3.9 RR and disco tanks, which are f*ck-off big thing incorporating the gauge unit as well.
coil is a possibility, make sure it's the right one too - electronic-ignition ones are different, different primary resistance ISTR.
