ok so i got an 91 EF, for a winter car for right now ( this thing it awsome in the snow) and soon to be my auto-X car. The car was moded to OBD1 and i got a cheap 1.5L to put in there right now just to get it to run. But when im at low RPM and give it a lil gas the motor shakes like there is a monkey in there going wild. I know wierd! but just need a lil direction in order to fix it. here is some pics!!!!

 

what do you mean by shakes? like runs rough? motor moves alot? need more info please

 

moves back and forth very fast it has a bad rear motor mount but i've never had a problem like this with a bad mount

 

i know what your talking about. My whole car shakes somewhere between 1.5-2 but at like 3 it runs smooth. I don't have an exact answer, but i think mines is like that because my exhaust pipe is sitting on the lca.

 

yea exactly ...but what is a lca?

 

lower control arm?

 

oooo well i have an apexi exhaust and it is a lil too big for the car.. what do u think should be done?

 

fix your broken motor mounts

 

hahah kk

 

Tune-up needed maybe?

My brother's CX ran rough under 3000rpm when he first got it. After a tune up(cap, rotor, wires, plugs, fuel filter, oil change, etc.) it ran much better.

 

I would almost definately fix the problem with the mount before resorting to all the tune up stuff, which could be costly.. and you would still have a broken engine mount.

 

Yeah my rear tranny mount is torn and it does that, when you cruise around and press the gas pedal, you feel the motor hop and the dashboard pops up lol.

 

An insert kit is 30-40$ from Energy suspension IIRC. Worth giving it a try. Tune up is always a good idea either way when you buy a new car, unless you know the stuff is fairly new.
