87 5spd situation......

[jlevie]

Sometime when I get going in first it doesn't accelerate like normal. The speedometer needle doesn't move and the idle is at 25-3000 and sounds very high. So I put it in 2nd and then it gets up and then I go back to 1st and its good.

That sounds like it might be a slipping clutch. Have a pro. Check out the car.

If the speedo doesn't work....hit it. Works everytine!

Vacuum leaks can cause things like an uneven idle/hiccup, stumble at partial or trailing throttle, and reduced fuel mileage. A smoke test is a common diagnostic for this, and if that doesn't find anything I would go to the AFM next.

I like to go fast that's why I bought a 5spd. Lol
Should there be any other noticeable issues with the vac leak?

[ELVA164]

As a side note, I never get much above 2000rpm on takeoff and the car picks up just fine. I'll admit that I hate slipping clutches and that I'm not that worried about blazing starts from every stop light, but it shouldn't be an issue to start from ~1500rpm. Helps you work on smoothness, too.

Ok great. Thanks!

It's not terrible but it is time to begin the search for vacuum leaks.
This is considered normal maintenance on an E30.
There is plenty of information on the Goog.
Good luck.

is it bad that its at 1250?

[randomtask37]

That idle sounds too high to me. Should be around 700ish

[IneedaRIDE]

It idles at 1250 rpms.
I finally drove it today to get a soda and it fired right up after a while of not being started
So I start to take off and it take right off.. Just perfect! I felt like a pro lol but like randomtask said I had it up in that rpm range but on a flat area..

[Pdxseth]

What does your car idle at?

[IneedaRIDE]

What if I up the idle rpm's a little bit? Or would that throw off my shifts between gears?

[Pdxseth]

Sounds to me like the amf. You pay shipping and I will send you a known good one to try out on there. But I need it back so you're gonna have to find one if that's the problem.

Without being able to drive the car it is hard to suggest what it might be. But the first thing that comes to mind is a worn and slipping clutch. My suggestion is to have the car examined by a pro.
