Throttle hesitation

shneidr · #1 03-18-2015, 05:23 AM

Hey,

I have tried searching the forum to see if I can find something close to my issue but haven't been able to find anything. If I am repeating something that has already been covered please direct me to the thread.

I have an 03 E53 3.0. The issue I am having is after about 30 minutes or when its warm my vehicle will start to act as if I am pulling the max load on a trailer. I press on the gas and the response is very hesitant. If I end up having to come to a stop, it will idle below 500 rpm. It will also stall if I do not shut it off soon. It is time for its regular service but I don't know if that is the issue.

Also in the regular drive mode it seems that it will shift at a higher rpm then normal or hesitate shifting gears.

Thanx for the imput.

Does your throttle respond normal when you rev it in neutral?
If it does, and the engine is otherwise acting nornmal, it could very well be your torque converter that is going south.

Mine behaved like that when the DISA valve failed.

Do you have CEL on?

To be honest idk what the CEL is. I don't think it does it when in neutral. Ill have to check next time it happens.

To be honest I think you need to bring it into a mechanic.

CEL = Check Engine Light

That's the funny thing no CEL. I need to get it read if there are any codes.

Ok hick update. I noticed the other day while driving on the autobahn/interstate, I was getting an up and down shack in the string wheel when I tried to accelerate. I was going about 80mph. What's even stranger is after about 10-15 it stopped doong the hesitation. If it was it wasn't noticeable. Any thoughts?

I still haven't gotten a chance to see if there are any codes being thrown.

I finally got the codes read, my O2 is bad and I'm getting a misfire on all 6 cylinders. Is there a distributor cap since a misfire in all cylinders in BMW's? Any idea on good spark plugs if I need to get them replaced?
