I've been told my 2.0L engine is running rich. Can anyone give me some tips on where to start to verify this and get it resolved? I am runnign the stock D-Jet FI.

Where to start? Fuel pressure (should be 29 PSI), check for unplugged hoses, cracked or leaking hoses, mis-routed hoses, wires that are not plugged in or are plugged in but not securely... Is the intake temperature sensor (two-wire sensor on top of the manifold) plugged in at all?
Maybe the MPS is toast. Pull a vacuum on it with a vacuum pump (e.g., Mity Vac) of about 15" and see if it holds for more than a few seconds. Lots of things could be causing it. Once, a chewed-up valve was causing it. It was an intake valve and the mixture was getting pushed back into the manifold, raising the pressure. The FI saw that "extra" air (which already had some fuel in it!) and dumped even more fuel in... Or you could have an ignition problem that is acting like a rich mixture. How's the timing?? --DD |
