What car / engine?

tock standard carby 1.6L twin cam, in the 1990 model corolla seca.

4-AgE

apprently i think? i hope heheh

yeh it might be the needle and seat, i dunno i think its carby, can any of u tell us how to check these probs?

4AGE is EFI (Electronic Fuel Injection), if thats what it is then it doesn't have a carby, If its a 4A-C then its got a carby..

 

To find out what it is read the ID tag on the firewall of your engine bay, it will tell you exactly what it is..

Or normally if u open ure bonet up and have a peek u can either see TWIN CAM written on the block, or u can see 4AC on a sticker on the right side of the block.

 

i know ure car, and i "think" it is the 4age, but the 86 Kw one.. i stand corrected tho !

Sounds like a 4afc. Twin cam carby.
