Ford Ranger

[Peter Shoebridge]

Any help/comment on the issue below would be greatly appreciated:

My friend has am '88 ford ranger 2.9 v6. I don't know too much about it but 
he has a problem with it stalling occasionally when taing his foot off the 
throttle. Doesn't seem to have any relation to temp, can happen straight 
after starting or after several hours of running. Only common aspect is 
going to closed throttle and sometimes it's fine, other it's not.

AFAIK plugs/leads/dist cap etc are all in good cond. It's been into a ford 
dealer and they couldn't fix it although I'm not sure how hard they 
tried......

Any advise welcome.

Thanks in advance
