BMW E36 Forum

Just noticed the other day that my car was begining to hop in 1st gear under heavy acceleration.
I remember someone on here looking for help to a similar problem. I began checking fuel and then the entire system today, started at the back and worked forward. No problems there
Took the car out for a spin for a closer feel to the problem, this time it was hopping (losing power then suddenly regaining power) badly in 1st and a little bit in 2nd. The slightest bit of acceleration in 1st was making it do it, i couldn't push the accelerator past 1/3 open before it would do it.
I drove the car very easily untill i got home.
I thought the diff might have some nasty particles in it that were jamming cogs under heavy load. No joy
Now i was getting pist right off!!!!!
No warning lights or anything. I decided to check air system and i found it. The intake pipe behind the air filter had a big rip in the under side.
A full morning wasted on a bit of rubber corrosion.

Well I spose the good thing is you fixed it and it wasn't a huge cost.
Thanks for letting us know hopefully it will help someone else in the future.

I didn't even think of doing a complete visual check, i don't know why but i just got it into my head that it was a fuel issue.
I got a soldering iron out and melted the rubber back together and then wrapped it in insulating tape. Forgot to say how i fixed it.

I wouldn.t have thought of the soldering iron tried that sort of thing b4 but never had much success but then thats me prob would have just used some duct tape(also known as gaffer, 100mph, cloth tape) and contact adhesave super glue is 1 of my fav fix it tools hahaha

Im a big fan of using the soldering and a hair dryer for repairing plastic and rubber ribs or cracks. After enough practice i can make it look like there was never a rip or crack in the plastic or rubber.
