1993 Buick Regal 4 cyl Two Wheel Drive Automatic

I did a full tune up on my car and now it is acting ( no wanting to GO ) I followed the instructions on spark gap but the plug gap was at 0.80 instead of 0.45 like it said to set it at should I put them back to 0.80 or what else could cause the car to act like it has no fuel

Your sparkplug type should be R44LTSM and the plug gap should be.035 correct it and makes sure all connections are nice and firm/tight.

Be advised stay in this post go back and delete the other one

Did you wire the plugs wires correctly, wrong type of plugs will make the engine idle erractically whether its gap properly or not-

Did you gap it yet or what?
