I've recently bought a 1996 2.0 AAC digifant transporter (its the facelifted model) and it isn't running right. The local garage I've used for years (who also has a 2.0 T4) reckons its running ok ("they're just slow mate, mines as bad"), but I took my mates 2.0 Caravelle out last night and it is def down on power and feels like its retarded.
In the past few weeks its had
Plugs, Cap, leads, rotor arm, coil, oil, oil filter, fuel filter, cambelt, 3mm vac hoses and Cat. Its got a K&N panel filter (which looks clean) and the catback section of exhaust is recent (but is quite loud). I also took a small amount of slack out of the throttle cable.
It does sound like it has a small crack in the exhaust manifold, but I wouldn't expect that to make a big dent in it.
Put a few more miles on it, bit of Italian tuning, but still the same lack of go.
Plus on a long hills needing foot in the carpet it feels like it surges on and off like the power is coming and going a little
On Monday, fire it up and it stalled straight away. restarted fine and was fine to work. got in it to come home, same again. Once home, tried a hot restart, all good. So next day I replaced the 2 pin temp sender (with one from just campers, £5 bargain) and it worked fine.
Today it went back into the garage to have the timing and codes checked.
The error codes came back with an immobilisers issue and the inlet temp sensor. They cleared the codes and nothing came back.
Ignition timing. Some work had obviously previously been done around this as the TDC mark on the flywheel had a big sploge of tip-ex on it and the dizzy looked pretty new (but needed a mole grip on it to move it). They initially followed the auto-data book on it and that was to run it to 1500 RPM with the temp sensor connected and set it to 6 deg. Tried that, worse.
So they then went with set it at 2000 RPM to 6 with the 2 pin sensor disconnected and the reconnect and check that its getting 20 deg. It isn't, its getting 12. But its back running where it was when I dropped it off.
Tomorrow I'm going to try cleaning the throttle body and the idle control valve, but other than that I'm stumped.
The garage is going to try retiming the cam as the belt needs to come back off as the backing plate is rubbing on the cam pulley again (it was broken when I 1st dropped it off and they tried to weld it but its pretty thin steel so looks like that didn't hold).
