How long did it take and how much did it cost if I could ask Malcolm? It's on my to-do list for this winter.

Everything was replaced Martin under the Intake including the injectors, ISV, TPS etc etc.

We also replaced all gaskets, t.stat etc related to the water bridge, the pwr strg res and both hoses, took both distis off to inspect them and rotors, the tbelt for tension, tighten all acc. belts, flushed the coolant, changed the oil and filter, wheels off to inspect shox and brakes, replaced 02 sensor, reset flex plate, checked auto tranny fluid and probably some more.

I believe parts were $1900 and I spent over 40HRS doing all but everything was cleaned to new spec.

Nice job Malcolm. I have 186k kms on my 87 and it is due for a lot of the same service. Does the 87 have the in tank fuel pump? Ican't tell from the parts catalogue. Did you have to adress any issues here?
Car looks great!!

thx Martin....bring the car over :)

The 87 does NOT have the intank pump so no worries but what I did advise the owner of this car is theres a few things that stop a 928 one being the fuel pump so part of all this work was to replace the fuel pump, the metal S pipe and the fuel filter and the respective copper washers.....cheap 'not get stranded' ins.;)

Hey Malcolm, it may be easier to swap the wires first before you get into the injectors?

Ya, if the plugs and wires don't change anything then recheck the dist caps, remove and lightly touch contacts with emery cloth including the rotor.

I would recheck the MAF connections and anything else electrical that you may have touched.
If you don't find anything then you have no choice but to go after the injectors

The new spark plugs or coil wires didnt cure the issue. I looked under the hood when it was pitch dark and theres quite a light show. we've found a big problem :)

Was in the big city for the last few days and met up w/Glen who has a spare set of wires, disti caps and rotors. I'll get them installed asap and see what happens.

Theres new parts enroute but this will give me a head start toward full diag.

Many thx Glen :)

Malcolm,
Good score! I would caution against using the Conti timing belt though. The Conti belt appears prone to an inordinate amount of stretch, which could activitate your TB warning light or worse.
