chrysler grand voyger cutting out when foot taken off accearator

I have a T reg grand voyger for the last 3 to 4 months at least three times
per week the car will just cut out when I take my foot off the accelarator.
This is sometimes very dangerous as I have no warning when its going to
happen It does'nt splutter and stall it just cuts out and I dont realize
till the power stearing has cut and the yellow coil light flashes. At
firdt it wont start and then after 1 minute it starts agin no problem.
The garage say until it wont start agin then they wont able to find the
cause of the problem, which is quite worrying as I often have five
children in the car and it has cut out on the motorway before. please
help! Ree

 

If you were to hold your foot on the gas pedal will it start and then die
out if you let your foot off?
If so have the throttle body cleaned out by someone who is familiar with you
vehicle.

Mine is doing the same thing. Would it be possible for me to clean it
myself and how would I do it?

Would carb cleaners work without dissembling it ?

Thanks Dog

 

You dont really have to remove it, Just hold it wide open (engine off) and
clean the inside bore of the throttle body and upper and lower part of the
throttle blade.
A gum cutter or throttle body cleaner with an old tooth brush ( or your
wifes) will work well

Thanks Maxpower! I'll try it tomorrow (with my wife's toothbrush.

 

Make sure the container of the cleaner you use specifically says it is
for *fuel injected* vehicles - there are some g.p. carburetor cleaners
that will destroy the o-rings used on fuel injectors. The manufacturer
that claims it is OK for use in fuel injected vehicles is certifying
that it does not contain chemicals that will damage the o-rings.

IOW, if there is no mention of fuel injection on the label or in the
name of the product, do not use it.

Thanks Bill. Will do.

 

Interesting Bill, Explain?. If you are spraying the cleaner into the
throttle body how is the cleaner going to get into the fuel rail to be
sprayed thru the injector?

 

You may be right about the Voyager. I was speaking in general. For
example, the fuel injectors in the LH cars are, according to the LH car
FSM, "in the cylinder heads with the nozzle ends directly above the
intake valve port". There are two o-rings: One where it seals to the
head (in intake air stream), and the other to the fuel rail. Of course
it is the former one that would be exposed to whatever cleaner is used
to clean the throttle body and would therefore be at risk.

Just curious: Are the fuel injectors in the Voyager engines not in the
intake side air flow downstream of the throttle body and sealed by an
o-ring at that interface?

I think the warning on that would be not to spray the liquid spray on the o
rings, such as bench cleaning. Im sure the possibility of swelling could
happen. but by spraying into the throttle body, I wouldnt think it would
cause a problem.

 

It may also be a matter of cracking ( = leaking) where it gets exposed.
I certainly will not take the risk on my cars.
