ok so on my 93 22RE after my motor warms up it seems to have a really rough idle. kinda like. guessing, it will rev up to about 3-3500 then back down to 1-1200 RPMs ive checked vaccums lines, and replaced the throtle pos. sensor. still it done it. but im hopefully droppin a new 22re in it this weekend. just ancase this motor does it. or if it ever happins again. does anybody know what might be the problem???

when i had a rough idle i did a basic tune up and the roughness was gone
