weird tug/jerk while i drive

[e30zues]

OK so for like the past month or so I been getting this tug/slight pull and it's pretty annoying while I'm driving. I've switched sparkplugs /wires/cap nrotor /fuel filter/ cleaned the injectors but can't seem to get to the source people say it's my gaskets others say it's my fuel pump so2 if anyone can help me out highly appreciate it

Is she hot? I like getting jerked while I drive. :giggle:

Be a little bit more specific like is it dropping rpm's?
Intake leak possibly...do a smoke test.

Oh and welcome!

E30GUS Lol Dayum u busting my balls well since the jerk started my rpm gauge was going crazy when I floored i t I don't see the rpm go down u can just feel the jerk/tug back when u are driving
what's a smoke test.?? O.o

Start by searching R3V, there is a wealth of knowledge/problems on here that have already been talked aboot.

Check your fuel rail pressure to make sure it isn't one of your pumps.
Could be an intake leak in which a smoke test would tell all.
Do you own a Bently manual? You have an E30=you need a bently.
Then search again!

Idle air control valve i have the same problam rite now but there not cheep

[hahaitzskippy]

the issue is worse for me between 1-2 RPM when cold.

not as apparent when it is warm or hot but it is there.

only happens when im holding the gas so when the RPM is between 1-2. as if the car isnt sure how much fuel to pump into the system or something...

SYa thats the same thing my e30's doing i replaced my iac with one from a junk yard and it solved the problam for a few month's but then that one took a dump on me and now my cars doing the same exact thing but be warned as i have found out to buy one new is not cheap but most of them have life time warenty and your lookin at around 200 bucks depending on where you get it
