Re: O/T Dodge TBI Troubles
Sound like you've already tried this, but I have a '91 Dakota with the same engine. It ran rich for long time... was ruining O2 sensor, etc. The shop kept telling me that the thermostat was bad. Finally, they compared the temp. the computer said the engine was running to a read off of an infrarred gun. Turns out the temp sensor for the computer was giving a faulty reading (too low) and mixture was constantly rich as a result.
