Help! Car jerks violently from 1st, 2nd and 3rd gear

[Luke721]

Gd afternoon all,

 

My bro's 91 Daihatsu charade just decided to fall sick - whenever he drives and switches from 1st to 3rd gear, the car jerks violently like a crazy bull!

 

The mec has checked and found nothing wrong with the pistons, spark plugs and radiator

 

Grateful if anyone could assist in this 'phenomenon'

 

Thanx a zil

I has this problem on my Mazda long time ago, but it was a leaky fuel hose where air is trapped in fuel line. During heavy acceleration, air went into the carb together with petrol and cause severe hesistation, ping and bounce.

 

Strange thing there is no fuel leak, no petrol smell either. i maybe wrong.

 

HAve u check other possibilities like faulty ignition, engine mounts and vaccum leak or the worst case timing belt slipped by one teeth?

Shag,

 

Thanx for the much needed advice!

 

Just got off the phone with him - now getting the mec to check

 

Thanks again for the inputs

 

 

Luke
