Have to floor it to get it started but cuts out and dies? We tried Putin sum fuel in the carborator it would stay started for a little longer then die. I don't know we however not to long ago replaced the alternator& fuel filter. It was running fine unroll we put in New sparkplugs?

It was OK, you put new plugs in, and now it won't stay running?

Are you sure you got the wires back on in the right order?

Did you install the same plugs that originally came in the vehicle? Cross-over plugs sometimes cause serious problems.
