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.
