A car question

My car (a petrol fuel injected runabout) runs fine till I decelerate. When I come to accelerate again it bunny-hops!
It doesn't stall whatever I do and if I decellerate without using the gears (clutch and brakes) it is fine accelerating
.

Any ideas what could be wrong?

These days with all the computers and sensors its tough to make a call without the device that reads the fault codes. A wild guess would be a fouled up sensor on the exhaust side making the computer change injector spray timing when you get back into it... Without the fault codes you could spend a ton of time and money chasing the unknown...

What make is it and engine size? It could be many things but maybe we can point you in the right direction. By the way is there a check engine light on?

This is way older than a fault code reader. I ride bikes and have banger cars for really bad weather.
Its a 15 year old French car.

If you are talking about a drivetrain issue,

If rear wheel drive, U-Joint could be about to snap...

If front wheel drive, CV joints could be shot and about to snap...

In either case, a bad Motor Mount could cause this as the "slack" is taken up.
