throttle response

[riceys1]

My 91 laser n/t throttle response is like a mack truck it lugs when you push the gas.It idles fine but when you hit it, it takes a while to rev up.Any ideas?

Sounds like a spark or fuel problem. Have you changed the fuel filter lately? Also, are you sure its not missing, which is usually caused by old spark plugs or spark plug wires? Sometimes you don't notice a car missing when its just idling. This is where I'd start.

Check your MAS, spark plugs, wires, coil, etc etc. It could be something as small as your gapping being off.

What is the correct gap?the book calls for .044. The wires and plugs are new as is the motor was just rebuilt.

Since you're N/T you don't need a tiny gap, but I'd try shortening it just a bit, say to 0.038". Also, you need to check the base timing with a timing light per the VFAQ.

How about look at the throttle cable adjustment?
