Car Forum / Chrysler Cars / December 200797 Voyager 3.3 HELP!!!
Having serious problems with my van..... :confused 1. Van intermittently stalls when coming to a stop or slowing to tur corners, all times - not just when cold. Somedays it doesn't happen.. the temperature or weather does not seem to matter. It always start right back up (that is until yesterday anyway...more on that in a bit 2. Driving down the road (speed does not matter - happens 35+) th vehicle will 'jerk', the check engine light will flash on and rpm guag does it's own thing.... this is all VERY BRIEF and at the same time... then it will give a slighter 'jerk' and go back to normal. (happens ou of the blue and I would say that the car is warmed up I can not get any codes to be read.... everytime I check it reads tha there aren't any codes found About a year ago the c.e.l. stayed on for a while (none of the othe problems described were happening yet) at that point the code suggeste a cam sensor, which was replaced (aftermarket). It was recentl suggested to me that it may in fact be the cam sensor again and t replace it with dealer part. Did that.... yesterday it died whil driving and now wouldn't start right back up.... I coasted it home an managed to get in the driveway and it started. (the car was warmed up Not relevant (I don't beleive) but recently the alternator went and i the midst of it I got a new problem... 3. Lights on diplay board for rear windsheild wipers (which i neve use LOL) and for the ac controls started flashing. They flash all o the time now, replaced the alternator with no effects on any of th above mentioned. (this doesn't really bother me that much and i certainly not on my FIRST TO FIX LIST, but thought I would mention al that is happening. Which reminds me...LOL the heater/ac fan switc only works on hi for about 3 months now. Again, not another biggie just thought i'd mention it I know the van is getting 'tired', but I need it to 'hang in' there bit longer... Just so you know... I have disconnected the battery and let it 'sit' bit to try and reset the computer..... but NO LUCK In advance I would like to Thank You for any input concerning thi problem -- novrain1 > About a year ago the c.e.l. stayed on for a while (none of the other > problems described were happening yet) at that point the code suggested [quoted text clipped - 3 lines] > driving and now wouldn't start right back up....

(the car was warmed up) Had some similar with an Opel only in autumn, till I disconnect every connection and cleaned with a contact cleaning fluid, coonectors from air-mass meter, throttle-valve sensor, etc. Regards, Ralf How are you checking for stored error codes? You really need to determine the error code from the check engine light. If it stays on, then AutoZone will read this for free if you have one in your area. It also would be helpful if you posted some other useful information as well, starting with the vehicle's mileage and the maintenance history (specifically, when was the throttle body last properly cleaned and when were the battery, plugs and ignition wires last changed)? What is the battery voltage (both when engine running and off) that led you to suspect and replace the alternator? Good luck. Many on this group will help you, but you need to provide more info to allow anyone to do more than just guess.

And when you go to AutoZone to have them pull codes, borrow their fuel pressure gauge and make sure you have a steady 42+ PSI. It could be the fuel pump starting to go bad. > How are you checking for stored error codes? You really need to determine > the error code from the check engine light.

IIRC the fix was simply to unplug the knock sensor itself.

(happens out > of the blue and I would say that the car is warmed up) Your fuel injection has a problem. The most common is that one of the sensors has gone bad and is intermittent and is giving intermittent inputs to the engine computer. This also could be a vacuum leak but most likely a sensor. Possible ones are cam sensor o2 sensor egr valve map sensor throttle position sensor vehicle speed sensor coolant temp sensor There is of course a possibility this could be low fuel pressure or bad ignition coil or wires but it doesen't sound like that. Particularly since most of the time the van starts right up again. For what it's worth, recently I had my van develop similar symptoms, problem was bad MAP sensor. I was lucky in that it did set a code. I also own a code scanner. But besides the MAP sensor code it also set a lot of other codes. Relying solely on codes can make you waste a whole lot of money. > I can not get any codes to be read.... everytime I check it reads that > there aren't any codes found. I hate to break it to you but if an engine sensor has gone intermittent it can do so in a way that is NOT detectible by the engine computer. Remember the old Garbage In Garbage Out for computer systems. The computer can easily detect sensors that have shorted or opened. But a failure where a sensor just starts reading off what it's supposed to be reading isn't going to always set a code. Particularly if the thing being measured is NOT a digital quantity. (ie: MAP sensor) However my personal opinion is that there's a code, your just not reading it properly. > About a year ago the c.e.l. stayed on for a while (none of the other > problems described were happening yet) at that point the code suggested > a cam sensor, which was replaced (aftermarket). In one of these designs I forget which, when the code says cam sensor it's actually the crank sensor, and when the code says crank sensor it's actually the cam sensor. > It was recently > suggested to me that it may in fact be the cam sensor again and to > replace it with dealer part. Did that.... yesterday it died while > driving and now wouldn't start right back up.... I coasted it home and > managed to get in the driveway and it started. (the car was warmed up) If your insistent on shotgunning then go to a wrecking yard and pull ALL of the sensors I mentioned and swap them in one at a time and cross you fingers and hope the ones you got from the wrecker are good. > Not relevant (I don't beleive) but recently the alternator went and in > the midst of it I got a new problem....

Now you see here is the problem, you have been putzing around with it for so long now that now something else has gone wrong and now you have 2 problems in the van. These may or may not be related, but you won't know if they are now because you've let it go. > I know the van is getting 'tired', but I need it to 'hang in' there a > bit longer.... > > Just so you know...

Yeah well these are the kinds of vehicles that get sold on the used market for pennies and picked up by someone who spends a few hundred bucks having a really competent mechanic diagnose it, and ends up with a vehicle that is worth a lot more money.
