what could this be?
When i accelerate in my 1987 mazda rx-7 it seems to like slow down and then speed up again and it idles wierd too (between 1000 and 1500 rpm) like when i want to really accelerate and go fast itll start goin and itll get to like 3000 or 4000 rpm and itll slowdown then speed up again, its notlike a cutout, it lasts longer than that, im thinkin i need new spark plugs or somthin, what do u allthink?

has it always idled like this? or just one day it started? usually that 1000-1500 idle would be caused from a bad or misadjusted TPS. your acceleration problems could also be caused from this.

open your hood and look at the 13B INJECTION cast into the throttle body. look directly down in front of that and there should be a black cylinder about 3 inches long and .5 wide...with a smaller cylinder about an inch long sticking out of it. this retracts inside the other one. the device itself is on a small mounting plate and has a decent size white plug attached to it. i've seen tons of pics online of it...but don't remember the addresses...
