95 Golf 1.6 (AEE) Accelerator Dead Spot - Phevans
Afternoon all

I've got a 1995 1.6 Golf with an AEE engine. It had to have some work done recently which involved disconnecting the ECU (don't know if this is relevant, but . . . ). Since then it's had an intermittent (but consistently intermittent!) dead spot on the accelerator. The dead spot is about in the middle of the pedal's travel, and corresponds to between about 65mph and ~100mph in 5th. This makes motorway driving very annoying :)

To go into a bit more detail:

- When I start the car, it's fine, but the idle's very high (2k - 2.5k rpm)
- After a few minutes driving (varies), the dead spot kicks in. This happens every time.
- If I'm in neutral for more than 30 seconds or so, the dead spot goes (but will come back in a couple of minutes)
- If I hold the accelerator in the dead spot position and depress the clutch, I can see the revs spike from ~1000rpm to ~1000rpm every second or so. Very odd!

Has anyone got any idea what could be going on here? There car's driveable, if very annoying, but it can't be doing the engine much good for it to be kicking in at full torque every now and again!

Cheers

Phil

Without a diagnostic check difficult to say & needs checking to make sure there are no air leaks on the induction side but I suspect it will be an air flow meter fault! the ECM had learn't the paremeters of the old one but once battery dissconnected couldn't relearn. AFM failure quite common

Cheers for the advice Doc :) I guess this is something best handled by a garage then? Any idea what kind of cost I should be looking at for a replacement AFM (if indeed it is that)?

It really does sound like you have a big air leak poss around the throttle housing or servo hose split. Find a good independent VW specialist & they should go straight to it
