long term throttle pressure drop out and fuel system running to lean

weeksuk

my cupra has been in and out of my local seat dealer for around 3 months now due to an engine mngt light issue.

The errors are always long term throttle pressure drop out and fuel system running to lean. When running the car it seems to hold back a lot and will then suddenly kick in, the revs also drop when the car is idle and it nearly stalls.

The garage have changed every valve within the turbo (more than once), have also changed the fuel filter, they are now going though and removing every piece of pipework from the engine and checking for damage.

Has the car had it or can anyone shed any light??

i had this problem, still have to a point. when the car tryed to stall it turned out to be the maf. had mine pluged into a super dupa computer that said the car suffered air pressure loss or along the lines of that. new maf= no probs, BUT it still holds back on throttle down. didnt know if it was turbo lag caused by heat soak???? is yours remaped???? if so maybe this could be the problem.

Holding back issue sounds like my own car but I gave up trying to solve it and actually have it booked in with Awesome GTi on Wednesday for them to take a look.

Ironically its not too bad at the moment ...

I would have told him to do one mate... private cars are sold as seen and the problem was not there when you sold it. :headhurt:

Remap has been done by chi**ed uk.
