Grand Voyager

[Soniabulpin]

Hi,

I have a grand voyager 3.3 2001 model.

Having lots of problems with it and even baffling the garages:-( it is gas converted but the problem is in petrol also.

It is automatic, it idles perfect and drives in reverse perfect. But if you select drive it splutters and does not want to go. The more you put your foot on the throttle it's worse, the Rev counter goes up and down on its own radomly but no acceleration. Have codes pointing to throttle position and idle air valve, also pcm.

Have cleaned the idle air sensor and the drove fine for 50 miles now back to square one!

Have changed spark plugs. Any help would be greatfull:-)

have you had any luck with this ?

No unfortunately not:-(

my car had spluttering problem lack power was v6 model turned out to be wiring fault with lambda sensor upstream

car would run fine for a while then when you put foot down nothing

check sensor code is p0134 this part 122.40 from chrysler can get next day 

hopes this helps 

also does car run rich or is your mpg down 

mine was 5 mpg round town 9mpg on run had this fixed now get 18mpg in town 31mpg on run

Thank you for your reply,

Mines doing a bit different to yours. Mine is spluttering as soon as you put it in drive. It's starting to stall now also.

[Soniabulpin]

There is someone on an American site with exactly my fault but doesn't say if it has been fixed or what the problem is :-(

My 06 3.3 gas converted vovoyager is doing a similar thing, started on the motorway when it wouldn't kickdown . best way to describe is it Feels similar to the clutch slipping, only happens when in drive and reverse, smart issue on petrol or gas. Haven't had it checked out yet, looking for some ideas first.

[Semmysonic]

Drove it a short way today and the issue has gone, starting to think it's a sensor somewhere as apposed to something mechanicalmechanical, will try to get it checked this week and report back with the results

[Soniabulpin]

Mines a bit different to that, we can't even get to about 20mph as it splutters and jerks so badly! Garages don't know what's wrong with it either:-(

[Semmysonic]

I've just read the codes on mine, it's a misfire on cylinder 6, just looking there is moisture around the exhaust manifold on cylinder 6. Not sure if this is the cause of my problem, going to the garage on Tuesday to get it checked

[Semmysonic]

Been to the garage today, over fueling is causing the misfire, mechanic didn't get too involved as he thinks it maybe to do with the gas system, going to a specialist to have it checked.

I'm starting to think it might be the plugs or leads now though.

Can't understand why it doesn't do it from cold (only once it's warmed up)

[Semmysonic]

Changed the plugs and it solved the problem. Took it for a drive about 20 miles, including mway, all was well until half a mile from home, when the misfire returned :-(

Hi

I see you are in Cambs.-------are you far from Mildenhall (Suffolk)-----there is a garage that specialises in Yank motors----they do warranty work for the USAF vehicles----------at least they are familiar with Chrysler vehicles-------MUCH better than paying someone to learn about them-------they have helped me in the past

I have now changed the leads and coil, seems to have cured it.

after doing a little research I found that running on gas requires almost double the voltage to ignite the fuel air mixture. Which means the ignition parts take a real hammering due to the extra juice going through them.

Worth a try as it only cost around £100

[Andrips]

Semmysonic, what make /brand leads and the coil you bought? I have similar issues on my new GV and I can find many different makes. Not sure which one to choose. Previous owner claims that he has changed the plugs some 10 k miles ago, I have seen receipt and some pictures, so could be the leads or coil.

[bignev]

I used Blueprint from our local motor factors last August when I did my leads and coil, and NGK Iridium plugs, but mine was preventative.

[Semmysonic]

Blueprint rings a bell but I'll have to check. After some research the best advice I found was, buy the best quality you can.

Even the best quality plugs only seem to last about 12 months or so.

[Semmysonic]

Also check the gaps on your plugs, lpg runs better with a slightly smaller gap than standard petrol plugs.

[Semmysonic]

Off the top of my head the gap should be about 0.8. Think I used ngk laserline plugs

[Andrips]

Thanks. Plugs were changed more than year ago,but not many miles done.so maybe than plugs are creating an issues.

[Semmysonic]

Garage did my last plug change during the service, done less than 5k in 12 months and they were past their best . try to go for a set developed for lpg, they aren't cheap but they make a difference.
