Cutting out on low revs and idle Db7

[ian lindsay]

Hi I took my 1996 db7 i6 out today for a run and it drove like a dream but on my way home it cut out and would not idle or work at low revs...help it's an auto

AMOC would be a better place to help you, mostly Gaydon cars / owners here

Hi Ian,
I'm not familiar with your car, but it sounds like it could be a problem with the idle air control valve(s).
These allow air to bypass the throttle butterflys when they are closed - they keep the idle steady and also help to slow the rate of shutdown of the throttle to make gear changes smoother.

It cold be a bad connection one of the IACVs - they should be located near the throttle butterflys, but may be slightly remote, with a tube going to the engine-side of the throttle.
Try removing/replacing the IACV connector plugs, in case there is a dodgy connection.

Cheers - Simon

Thanks Simon. I had a look at the connections this morning I could not see anything obvious also it would not start at all . Its a pain once again thanks

Rubber hose from inlet manifold to MAF could be the problem. Might be blocked.

Pull off the hose and clear it with a long wire

Look under the manifold for this hose.

Well that was a long day...Turns out the fuse had blown on the primary fuel pump and that is why it was cutting out and only running at high revs...thanks for your input guys. That's 8 hours I will never get back

Bugger I was going to say "fuel pump?" but I did not have the courage of my conviction and did not wnt to send you on a wild goose chase. Glad you got it sorted.
