running rich
#2
ummm that would not cause you to run rich .. that would just cause bad emissions which could cause your eyes to burn
if you are running rich ... start checking sensors... is the ECU throwing a code? if so which one?

there are two sensors that govern fueling at startup - Engine Coolant Temperature Sensor, and Intake Air Temperature Sensor.
If those two check out, move onto TPS sensor and MAP sensors. The test procedure for each is in the Chilton manual.

take out the ECTS and test it in hot water. in the chilton there is a resistance table for each temperature range. it may be thinking that it's really cold outside, in which case cars run better rich (easier starting) so it dumps lotsa fuel in.

b....its not only on startup its running rich,
it runs pretty black when i start it up, the plugs are BLACK carbon, then the temp rises and fan comes on, its not that bad, then if i crack the throttle a bit i see it come out again.

The ECTS governs it all the time. In some cases, there are two ECTS's one for the temp gauge, the other for the ECU only. The ECU one may have failed or may be working half-assed. It's worth checking out. Another one is IAT sensor, just hook up an ohm meter to it, and then warm the sensor side of it with your hands, and see if the resistance changes smoothly as it should. If not, then it's telling the engine the intake air is way colder than it really is. I'm not that familiar with the 4th gen models, so I don't know if you have one or two ECTSs. Basically what you need to do is check under Emissions and Driveability section in your manual to see the sensors involved in closed loop operation, and test each sensor according to the procedures.
