Cold Start Problem 700 1991

Not clear. It idles excessively or does not idles well. If it will not run properly for a few minutes and then smooths out, could be your temperature sensor in the block (under intake manifold). If so, you are actually running too rich until the temperature changes the resistance of the sensor to the computer.

If you start the engine, run it for a few seconds, stop it and then pull a spark plug and see it is wet, then the temp sensor could be your problem. ($35.00)
