#591 of 4276 Increased hydrocarbons at idle
Dec 30, 2000 (4:05 pm)
I own a 1995 Dodge Caravan with a 3.0 motor with 82000 miles on it. This past month, this vehicle failed the PA state emissions testing. The problem is that at idle, the hydrocarbons are too high and the hotter it gets the worse it is. However, at 2500 RPM the hydrocarbons drop down to an acceptable level. Since the first test, I changed spark plugs, spark plug wires, distributor cap and rotor, PCV valve, and replaced a bad fuel injector. On retest the same results were obtained. The idle is a little rough at rest but off idle it runs fine--no hesitation. Any ideas greatly appreciated.

Possibly an O2 sensor?

#595 of 4276 95 dodge caravan, 3.0 , intermittent engine dying
Jan 03, 2001 (2:47 pm)
I have a 95 Caravan and the engine intermittently dies. As long as I constantly give it gas it will run but, if I pull up to a stop sign and take my foot off the gas it will cut off. The van will re start as long as I keep the gas pressed. In order to pull away I will have to keep some gas applied as I put the van in gear (with brake applied). This problem may not happen for over a month and then it happens all the time.
The engine sounds like it is not getting enough gas or maybe oxygen. I don't have an idea what may be wrong but the dealer says it needs I happen while they have it on a computer. There is no indication that anything is wrong on the diagnostic. HELP ME PLEASE....

jdowens: My Haynes manual has the following sources for "Engine Stalls": 1. Incorrect idle speed, 2. Fuel filter clogged, 3. Distributor components damp or damaged, 4. Faulty fuel system or emission control system sensors, 5. Faulty emission components, 6. Faulty or incorrectly gapped spark plugs or plug wire faulty, 7. Vacuum leak at throttle body, intake manifold or vacuum hoses. Your case is complicated by intermittent malfunction and apparently no sensor error codes. So it is not a typical failure of a distributor, sensor, etc. It could be a clogged fuel filter or maybe a fuel injector malfunction or an intermittent vacuum hose leak. I would be sure to be up to date on preventive care such as PCV and fuel filter replacement as well as inspection of distributor cap and rotor and vacuum hoses. When the problem is occurring, inspection of the plug wires for arcing under low light. If the fuel level makes a difference, the fuel pump is suspect, usually with low fuel allowing the pump to get too hot and drop fuel pressure. You may ultimately need a continuous diagnostic computer and a problem that can be expected within a reasonably short time. The following is an interesting discussion of fuel injection function and diagnosis:
#597 of 4276 Front wheels pull to the right
Jan 05, 2001 (4:38 pm)
If you are getting a slight wobble feeling in the front wheels I'ld venture to bet it's your transaxils...mine did the same thing anf both transaxils were out...I replaced them and the front stopped pulling and the wobble disappeared. By the way that was my second set of transaxils in two years and I don't drive my vehicle hard.
#598 of 4276 craigwilsontx - Ignition cylinder or Neutral Switch
Jan 05, 2001 (7:59 pm)
I posted a problems similar to your (late Dec). My was corrected by the replacement of the Ignition cyclinder. My syptoms were a little more serious in that I had some electrical problems associated with it -- but the Service Manager said that the Ignition and Steering column was so complex, it can affect alot of things.
Previously I had a vehicle (non-Chrysler) that also had problems like yours. It was a defective Neutral Switch,...could be somewhat related as it too is based in the Steering column / Ignition.
Hope my experiences help....good luck.
#599 of 4276 Leaking intake @ 15K miles?
Jan 06, 2001 (9:57 am)
It seems our 2000 Chrysler Town and Country, 3.3L V6, has developed a coolant leak where the intake manifold meets the cylinder head. There is crusty red and white coolant residue all along the back side of the intake, and along 3 inches in the front near the driver's side. It seems there are a couple of small wet spots, but it's hard to tell for sure since the coolant boils off the hot engine right away. This seems quite odd for a vehicle with only 15,000 miles on it. Has anyone else had this problem, or are we just lucky?
#600 of 4276 2000 Dodge Caravan Base
Jan 07, 2001 (7:09 am)
2000 Dodge Caravan Base with only 2,400 miles. Oil is leaking from top of engine. Low wash light came out indicating that the windshield washer fluid was low even though is full. Took it to the dealer yesterday. Let see what they have to say this week. I am wondering if they sold me this van with rebuild parts. Any suggestions. Thanks
