chrysler grand voyger cutting out when foot taken off accearator

accelarator.

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.
