E30 318i Potentially Major Problem

[dannie 0]

Hi,

I'm new the forums, some of you may know 'tastic', I bought his e30 318i 86' off him.

About a week ago I was going down a long straight and for some stupid reason I went to 50km's in 1st gear, after that the engine just sort of cut out and the rev counter went down to 1000. I pulled over and turned the car off for a while, started it back up and still with my foot to the floor the car would not rev higher that 1000 (in neutral).

So I bunny hopped half way home at a max speed of 15km's in 2nd gear, not going over 1000rpm, I pulled over again and switched the car off for a good 10mins then started it back up. It then was able to rev fine and I got home fine. Anyway later on that night I went into town and all was good but when I was sitting in my car park it started doing it again and it wouldn't go higher that 1000rpm, so I did the only thing I could do at the time and planted my foot right to the floor as hard as I could and after about 5 seconds it shot up to 7000rpm instantly.

Now the car has been running fine for the last week or so but today it started doing it again so I had to plant my foot down to uncap the permanent idle at 1000.

Does anybody know what is going on here, I am going to take it into a garage when I get paid.

Thanks,

Dan

Sticky throttle or AFM sticking/malfunctioning. I've had issues with AFM's where they would suddenly give me a sort of limiter at certain RPM as if I was hitting an electronic rev limiter. It was random also, I for a while thought it only happend when the car would heat up.

It could always be something else though?

check the rotor -see if the cutout spring is not broken and feel if the rotor is tight fitting on the shaft
