VTII jerking under load

[Muttley]

I am hoping someone can help me. I did a search but found nothing.

Have a VTII Berlina with around 135k on the clock. When under load, say pulling up a hill, it tends to give a strong kick, like it's missed a beat. It's especially bad in top gear, until it changes down (auto) and the revs pick up, but it has also been known to do it in the lower gears. At first I thought maybe plugs and/or leads, but would that be affected by load or engine speed? What else? Something in the gearbox perhaps? or a uni joint or something?

Any help appreciated.

My guess is sparkplug lead. The can fail under load.

so can plugs, id say start with the basics, air filter, fuel filters plugs and leads.

mate had a similar prob...turned out to be the throttle position sensor

 

[Muttley]

Ok. Plugs and leads are easy to do so will give that a go first. Air filter is fairly new but will check it anyway. Thanks for the replies.

do any lights come up on the dash wen it breaks down?

 

[Muttley]

No lights or any other indication.

 

[veclubby]

should be just leads or plugs then....check that and see how u go....on my mates wen it was the throttle position sensor the engine light kept flashing up on the dash so i dont think its that....:thumbsup:

hope that helps mate

also it won't hurt to check your error codes too

yeah throttle position switch can do all sorts of stupid things, thought my tranny was stuffed in the stato as it was slamming into gear and revving right out ended up beeing my throttle position switch
