Recently bought a mk1 Leon cupra r 132k 52 plate when the maf sensor is plugged it it ticks over fine but just splutters when I drive. When I unplug it it tick over like crap revving it’s self from 500rpm to 1500rpm but it drives fine when you get going. Got a new sensor and it’s stoll doing the same? Any ideas what it could be? Car has a bad exhaust leak from behind the engine that’s getting fixed Next week. Could this be the problem?

Could quite possibly be because of the exhaust leak messing up the readings from the lambda sensors.

Unplugging the MAF will put the engine in a kind off 'best guess' mode so can hide many problems such as exhaust/ intake leaks!

If i was you id wait and see if getting the exhaust fixed cures the problem!
