I'm losing my mind over this.....
My SPI intermittently hesitates when i accelerate (not specifically when the engine is hot or cold).
I've taken it to a garage and they've changed the:
Breather Purge Valve
manifold sensors (lambda / temp .etc)
and its still Hesitating!
As part of my own fault finding, I've notices that there is a bit (tiny amounts) of fuel in the vac lines going from inlet manifold to fuel trap, and from the fuel trap to the ecu... I'm going to safety assume the fuel trap should prevent fuel from going into the Fuel Trap --> ecu vac line! Theres also a what appears to be a tiny amount of 'brownish coloured' residue coming from the MAP sensor port on the ECU - my guess is thats petrol!? Am i right in thinking its a good suggestion to take the ECU out and place it over a radiator for a few days to drain any fluids out of the sensor port?
Ive blown through and inspected the ends of the 2 vac lines mentioned above - as per Sprockets helpful SPI thread but its still hesitating!
Is a good bet to replace these 2 vac lines and fuel trap for new ones - just in case there is any left over petrol residue? (the other vac line to the air filter is all good)
any help would be appreciated!
