Hi all, im new to this forum,

I just aquried an ED XR8 fairmont that had a slight fire under the bonnet (not an electrical fire), I have repaired all burnt wiring and it is running really rich and wont rev past 4000 rpm.

I have removed ECU and had it checked out,
I have checked injectors are pulsing and not stuck open,
Has new dizzy cap, leads and plugs,

Not sure what to do next, any advice is welcome.
cheers

Check O2 sensor, check for any vacuum leak, blocked catalytic converter?, check fuel regulator. That's all I can think off, not well versed with V8 so someone else might chime in.

I found a vac leak which made a little different,
Only engine code im getting is 85 (purge canister circuit fault) which i believe wouldnt cause this kind of trouble.

If you have a code for the purge canister, i would investigate that first.
