Need help with 92 lt1 running rough
The engine runs great until it reaches operating temp, then it seems like a fouled plug. I keep threatening to get an OBD1, just havent yet. Any ideas what to look for? Thanks

Have you tried pulling codes using the paper clip method?

Under dash on drivers side jump out with paper clip. You will not get any thing of value. The OB1 system sucks. Go to Auto Zone let them pull the codes for free or Oreilys . No codes just go out and buy the service manual for your car and read and read eventualy you will step by step find the problem .The other thing call that radio program the car doctor .
