I have recently acquired a 1996 URS6 running circa 400whp with a Gt3071R, I'm struggling to pass the UK exhaust emissions test as it is running very rich indeed
Parts checked so far..........(updated as I check)
ECU coolant temp sensor
Lambda sensor
FPR 4bar
Vacuum lines
Pressure tested intercooler pipes and hoses
Does this leave me with the MAF, MAP and FPR?
When unplugging the MAF at idle the engine changes note and speed significantly
I plan to fit a Wideband to see what the actual AFR is but before this any help is greatfully appreciated
