Slow throttle responce

Ok so I got my 1987 VW cabriolet running after it had been sitting for about 2 years, it has a few vacuum leaks, but some of them are plugged. When I press the throttle wether its an inch down or all the way or any in between (in Neutral) it takes about 3-4 seconds before it even starts to increase the RPM's and then it goes up to the speed. (dosnt change wether its in neutral or any gear)
The car is 5spd which im trying to lean how to drive, with the help of my dad its easy but with it running this bad its hard to drive.....alos the gas petal is quite stiff, but dosnt stick.... ok to WD40 the cable it has???

You can lube the cable. I use a graphite lube for stuff like that.

As for the poor running, before you tear into it, try Sea Foam (from auto parts store or Walmart) in the gas and oil. Just follow the directions on the can.

If this happens to have a carburetor - the carburetors I am familiar with all had an "accelerator pump".

The idea of these plunger devices built into the carb was to eliminate the very problem you are having. And if the accelerator pump seal goes bad, (or even if the float level is too low for the the accelerator pump chamber to have gas in it) you have the very problem you speak of; one big flat spot - a big power lag - when stepping on the gas.

If fuel injected - never mind.
