Engine continues to run after switching off ignition..?

[Stubs]

to all you boffins out there, lately when I switch off my ignition, the engine continues to run for a few more revolutions then eventually dies, if I switch back on again and start and then switch off it shuts down immediately, can anyone let me know the cause and fix for this, is it ignition based or something to do with the starter motor ???

cheers Stubster,

You need to change your plugs to a colder rated plug. Yours become to hot and pre ignites the fuel

you got me there cassie, thought plugs were plugs, just different brands but the part number was the same

but its never happened before so why now, have been running same plugs all along ??

[CasKru]

I'm not sure if that could be the only cause but it most definitely is one of the causes of pre-ignition. There is another thread here somewhere on the forum regarding this. Will try and find it

Have you changed the timming?
Too advanced timming can also cause preignition.

Common Ford problem... called run-on... they been working on a fix since 1975! In 1985 they thought they had solved it, turned out the motor was siezed! Back to drawing board then...

You wanted a Ford V6!

[Stubs]

and I do but thanks for the advice

[Hilux 1]

i bet you its something called FORD, thats the problem

[zepplin]

Stu, colder plugs & retard the timing a tad - problem solved.

Hi Stuart.
Ek weet my mazda V6 het n electronical idling jet gehad.
As joune een op het is ek heeltemal oortuig dat hy vashaak
En nie toemaak nie. Dit is n klein siliniod valve op die carb.

The hilux don't like the ford motor and it doesn't like being called a Hiford or fordlux

OR your motor is "DIESILING". main cause is over fueling..
or it could be the modulator (if you got electronic ignition)
if it just started to do it it wont be te timing.

P/S mine started a while ago now it just stoped cause iam driving it easier.
try to idel for a few seconds befor switching off so it can burn the unburned fuel then it wont DIESEL.

or it could be the gaps of your spark plugs

Stubs
Still in Limpopo ?
If so May be timing, since i', sure it was last done at the coast

[Stubs]

Hi george, yeah still in Nylstroom...didnt think about the altitude....

The motor wil rather have a pinging noise at low revs
when you put pedal to the metal due to the difference of altitude,
Rather than pre ignite (dieseling)

Put Toyota engine back-problem solved

Spark plugs for this motor recommended by Ford (sticker on V6 tappet cover) NGK BPR6ES

[Stubs]

Hi Andrew, yes am running those plugs, now I have just come back from a 4 day trip to kruger, Skukuza, lower sabie, back via Graskop, gods window, potholes, pilgrims rest, marble hall and back Nylstroom etc and the motor didnt preignite once ?? however what I did notice the closer I got to the kruger the engine would stutter everynow and then as though it was crap in the carb etc but I see no indication on the rev counter which stays firm and relevant revs, then once back pass pilgrims rest the engine was fine, so dont know if thats a combination of altitude, crap in the fuel tanks, carb maybe needs a service etc....but otherwise I love the V6..I think once back in the cape I will take to Hoppy just to give it a retune and clean the weber as I do have a small flat spot in first pulling away but nothing hectic...

Stuart,
Please check the fuel cut off solenoid. (If you have a carb) Sometimes these things become faulty and they don't cut the fuel off when the ignition is switched off. But also the can cut the fuel whilst you are driving. I would simply buy a new one because they are pretty cheap. At least one potential problem would have been ruled out. In all likelyhood that is part of your problem.

[pietpetoors]

Stubs is still on the road but it turned out that this problem

however what I did notice the closer I got to the kruger the engine would stutter everynow and then as though it was crap in the carb

was the graphite pin inside the distributor cap were worn away

[Mr_B]

I saw Stubs this morning on the road... by the looks and sound of it that Ford V6 is happier in Cape Town! As it should be hey!
