Question...

[Kaldar142]

Okay so,

I picked up a automatic 89 325is and had a few questions.

The tachometer only goes to 5000, I thought 325is had the 7000 rpm tach? Is it because it's auto?

The speedo does not work at all and the gas gauge goes crazy.

It has a rough idle and when I rev it, when it comes back down the rpms dip and sounds like it will die but it catches.

Lastly, the car is really slow LOL...

[Kaldar142]

The abs light is also on and so is that weird inspection light

[kamotors]

either its a 325e or someone swapped the cluster. the idle dipping than catching could be the car running rich, whats the temp gauge at when this happens? have you tried replacing anything?

[jrdeamicis]

Get a service manual.

[Kaldar142]

No have not replaced anything, the title says it's a 325is but is there a way I can check the vin?

It does it cold, I actually have not even let the car warm up yet. I just picked it up the other day with a trailer and only moved from trailer to garage. Just took a lap around the neighborhood (no tags)

when the engine is cold it is sending a lot more fuel than normal, I wouldn't be super worried about hesitation when the engine is cold,check if it also hesitates when fully warmed up.

The speedo does not work at all and the gas gauge goes crazy. - speedo circuit board might need to be re-soldered

It has a rough idle and when I rev it, when it comes back down the rpms dip and sounds like it will die but it catches. vac leak

Lastly, the car is really slow LOL...seeeaaaafoooaammmm

[lukem23]

when i had a hesitation problem it was my afm.

[Kaldar142]

haha, you guys think seafoaming this mother fucker will help? i've had some great success with it in the past but never on an an engine / car this old LOL

why would someone swap to an ETA cluster?? lol

do you think getting a whole different cluster all together (the proper one at that) will help with my gauge issues? (speedo, gas gauge... etc)

lastly how do i check for vac leaks or rather... where are the most common leaks at?

[Wh33lhop]

Get on it hard. Will the tach go past 5k or does it bounce off of a 4500rpm limiter?

If it's really an eta then a) you kind of got jipped and b) that explains why it's so slow. automatic etas aren't exactly speed demons, hell 325i 5 speeds are ok but nothing special.

[Kaldar142]

it went shooting past 4500, actually way past 5 too lol i guess that means i'm OK.


so i seafoamed it today and OMG, it made a HUGE difference WOW WOW WOW the car actually sounds good now :) no more stumbling or choppiness

[Kaldar142]

sooo now that its running fine, what about the ABS light?

So it went to about 6-6.5k?

Check your ABS relay, should be the polished silver relay hanging under the steering column. I'm told this is the most common fault in the ABS system.

Could be a wheel speed sensor as well.

Or a bunch of other things.

Really just go out and buy a Bentley manual. It's well worth the $30, and you'll learn a lot about your car in the process.

yes
