I have this exact same problem too, Zoe cuts out at about 6500rpm which is really annoying.... and sometimes when i pull up at a set of lights the revs will drop and she'll stall. I always look after the engine and I recently replaced the coils and plugs so i knew it wasn't that, i thought it was the turbo because it's what, 20-something years old now, so i took it to precision turbo and had it rebuilt & high flowed for $1350, ........but still it cut out! epic fail! but it does have alot more power now, i thought i'd have a look on here before i went throwing more money around, so tomorrow i'm gona try this contact cleaner for the AFM and if it doesn't work i'll replace it, thanks for the heads up about it, much appriciated (^_^!)
