Running rich on fuel?

[Hairytoad]

What are the ways to fix running rich on fuel on the 94's.. i know a lot of that bs is computer done, so i expect it would cost a lot but im just kind of curious... Also is it that big of a deal to worry about? thanks

unless it is running terribly rich I wouldnt think it would be that big of a deal...possibly the temp sensor may have some issues. If the computer thinks it is colder outside than it is it would run rich...

could be a bad O2 sensor.
Could be a dirty Mass Air Flow Sensor(use the keyboard cleaner spay that you get at like best buy and just spray it towards the wires in the maf..just don't break them loose).

I would bet on an O2 sensor..but just unhook the negative battery cable for 2 minutes, let it idle for a minute or 2 then go out and drive. If that doesn't work, check the O2s if you shake them and they rattle you need new ones.

Okay thanks i'll try that, are the o2 sensors exspensive or hard to fix?

Try runnin codes first to try to pinpoint the problem. A rich engine can foul plugs prematurely and cause excessive damage to the catalytic converter.
