325e 1st gear accel

[e30_fett]

So I have an 86 325e and when I punch it in 1st gear it acts like its counting to 3, in means of revvv.pause, revvv, pause, rev the in goes to its limit of 4800 or so its wierd cause no other gear does this as bad. I have bavarion motorsports plug wires, bosh platnem 4's and a cai. any thoughts? I would like to get this fixed before any other mods are done. Thank you

It has been doing this since before the upgraded intake,plugs,and wires.

Stick shift? If so, may I suggest a new clutch?

[e30_fett]

No its an automatic. No vaccum leaks cause all the hoses are new, was thinking o2 sensor or throttle sensor.

Maybe a plugged fuel filter or faulty fuel pump relay?

Bad first gear clutch in the trans is a possibility too. Could be slipping. Check trans fluid, see what colour it is. Make sure its not black and smells like burning

Trans fluid is good its been changed with lucas juice, I was reading through all these forum pages and read about a tps making a click when it is engaged, mine makes no noises at all.....really hope its not a 1st gear cluth. Thanks for the responses.

even tho its brand new fluid, smell it. If it smells burnt, its usually a bad sign. Also, this lucas stuff, I DONT know exactly what kind of fluid a BMW auto takes for one this old, but does this Lucas stuff comply with the use in that particular auto trans? If not, replace it with what it RECOMMENDS to use, coz if you use a fluid type that is NOT recommended, it WILL do a bad number on a trans. K, so I just looked up the spec on Alldata, and it requires Dex 3. But since Dex 3 is no longer easy to obtain, you use either Dex/Merc, OR Dex 4. So if this Lucas stuff is not Dex/Merc or Dex 4 compatible fluid, replace it with Dex/Merc or Dex 4. I recently was trying to find Dex 3 for a powerglide trans service I did on my dads Chevelle, and I couldnt find Dex 3 at NAPA, so I used Dex/Merc coz thats what I could find.

The lucas trans stuff is for all transmission types, but it did that before I changed it. So should I smell the fluid when its warm or does it matter?

So I took off the stock tips to the spark plugs and put the ones on that bavarian auto gave me with my wire set. As I was doing this I noticed a ajustable regulator from following the hose from the intake boot, I turned the car on and held the trottle open half way and with a flat head I ajusted this till I heard a good sounding engine. I went for a test drive and punched it in 1st, no problem revving all the way to its weak 4800 point. Seems to have fixed the problem for now. "fingers crossed"

For smelling the fluid, it dont matter whether its warm or cold. Youll smell it either way

[e30_fett]

Well it just smelled like trans fluid not burnt rubber or anything.

Haha its probly fine if your last post is correct about fixing it. It wont smell like burned rubber, itll smell like burning wet clutch material.

So the problem was these bosh platnium plugs, they are juck and my car requires silver plugs. Guess thats what I get for listening to auto zone techs.

I've never really been a fan of Bosch platinum plugs.
