Help - my new to me 1973 1.7 Djet came running really sweet, but almost immediately developed the 'hunting tick-over' of lean running / air leak. We replaced all the vacuum pipes, found one of the inlet gaskets had a very slight leak. Seems somewhere along the line things have been tweaked to compensate for the leaks so that now they're cured, the car is running super rich. Having had a L-jet for years the Djet is new to me so any advice on where to start first would be much appreciated. Thanks Chris

Pull a vacuum on your MPS
Make sure your diaphragm isn't cracked |

Pull a vacuum on your MPS Make sure your diaphragm isn't cracked (IMG:style_emoticons/default/agree.gif) See if it's been opened before, too. If it holds vacuum but has been opened up (rivets replaced with screws), it may need calibrating for your engine. Also make sure the ECU and MPS match & are correct models for your car. |
