1987 Pontiac Fiero my car stalls when given gas

Check your fuel filter or just replace it. The fiero had heat problems due to engine placement and you may replace the distributor cap and spark plug wires. Especially if this hasn't been done recently. Then after doing this remove the air cleaner and spray some choke cleaner on the idle air control valve as it is probably gummed up as well. If you don't know what it is or where it's located then have a mechanic do it.
