#338 of 378 Re: Leaking power steering fluid [tommy97] - UPDATE by tommy97 May 16, 2009 (6:47 am)
Replying to: tommy97 (May 15, 2009 11:46 am) I now know that the leak is caused by a suspicious "pin prick" hole in the pressurized line about 2" from the lower fitting (steering knuckle side). When the front wheels are steered, a tiny geyser appears.   Recall that this line is covered by a slit, corrugated plastic sheath for protection. What are the chances that this hole was caused by "natural" (i.e., not nefarious) causes?    I think I know the answer but thought I'd put the question out there ...   Replies to this message: bpeebles (May 16, 2009 4:32 pm)

But there is no such thing as a perfect machine. Unless you have good reason to consider anything else, you have to assume it is simply a natural failure.

Replying to: tommy97 (May 15, 2009 11:46 am) BPeebles is probably right - I'm willing to accept that the leak in the pressurized p/s line is a "normal" failure. I've also heard other anecdotal experience of the same kind: this line does develop leaks. The good news is that AutoZone had a new hose ("Duralast" brand) - lifetime warranty - for $17.99. I'll replace the line today.   Now let's turn to the Check Engine message I mentioned. I pulled the code and it's P0132 (O2 Sensor Circuit High Voltage). Sensor 1 & 2 on Bank 1 read "1000V 0% S.T. fuel trim". This strikes me as a possible short.   Again I refer back to posts 227 & 228 on this forum, which point to the possibility that the p/s line leak (a mini geyser at times) may have put fluid on the O2 sensors (which I suspect are in that region of the engine area).   I had only one instance of a real sloppy power failure in the last 2 weeks and it seemed to have "recovered". If this theory is valid, I wonder if it's fair to assume the the fluid wetted O2 sensors will "dry out" and eventually go back to normal.
#341 of 378 Overheating by goose1956 Jun 10, 2009 (3:10 pm)
Have a 2000 dakota, V-6, 315000 miles, overheating, checked coolant, flushed, recently change water pump, head gaskets do not appear leaking by checking rear exhaust. I was told check timing, could this be it, any other suggestions beside a different pickup.
#342 of 378 Idle Surge and Hesitation/Surge while in Cruise Control by wrestlingref21 Jun 16, 2009 (10:38 am)
Hello,   I have a question regarding my 2000 Dodge Dakota 4.7L V-8, with 117,000 miles. A couple of months ago, I noticed while having my cruise control set at 60 mph and my rpm setting at 2, that the engine would "surge" just above 2 after going over a slight "rise" in the road (not during) and then go back to 2 on the rpm display. After slowing down and re-activating the cruise control at around 50-55 mph, I would notice as the stick arrived at 60 mph, the engine would give a quick surge slightly above 2 and go back to 2. I added STP Fuel Injector cleaner on three occasions, and it seemed to help temporarily, but it is back and occurs more frequently, even when not going over any rise in the road.   Additionally, about a month ago I noticed that when I would start my truck up in the morning, it would surge while idle then come back down, then surge again, and so on.   Could these two issues be related and what should I be looking at? I was looking online a little, and one suggestion was made regarding the idle surge as it relates to the IAC valve. Any help would be much appreciated!

#344 of 378 Roaring engine at start up by bone5 Jun 30, 2009 (7:09 am)
2000 dodge dakota quad cab 4.7 engine roars when started up and roars for a couple of miles down the road. It sounds normal after about 2 miles down the road. It seems worse in the winter. What could be the cause of this? Replies to this message: bpeebles (Jul 03, 2009 6:20 pm)

Replying to: bone5 (Jun 30, 2009 7:09 am) Totally normal.... You are hearing the roar of the thermostatic engine-fan. The thermostatic fan takes awhile to disenguage. As I recall, it is the very worst right around 40F.   You can reduce the time it takes to disenguage by gently reving the engine for 30 seconds or so before putting into gear and driving....but why waste the gasoline?   Technical details: Silicone fluid withn the thermostatic-coupling is 'stiff' and takes awhile to get thrown to the outer-edges by centripital force.   BTW: If you had use the "search" feature, you would have found several discussions about this since the 4.7L engine was put into the Dak in 2000. Many people mistakenly think that their automatic-xmission is "slipping" when cold.... as least you did not make that assumption.
#346 of 378 Hard restarting by selene Jul 05, 2009 (11:18 am)
I have a 1993 dodge dakota with a 3.9 liter v-6. The check engine light is on. I turn the key 4 times to get the trouble codes. The codes I have gotten are 22, 23, and 45. I have replaced the coolant temp sensor, the throttle position sensor, the intake ambient air temperature sensor, the Oxygen sensor, the pcv valve , and the air intake filter. The engine is hard to start. After the engine is hot and I kill the engine, trying to restart is hit and miss. Sometimes it will start right up and other times it won't. Then it will act as if it is flooded. It won't idle. I rev the engine a little and the rpm's will finally kick up to around 1500. Then the engine will run smooth. The codes I get now are 45 and 22. I can't understand what is going on. Any help will be greatly appreciated. Also, is the heater/AC blower resistor located in the engine compartment on the R/H firewall on a '93 Dakota? Thanks.
#347 of 378 Re: Idle Surge and Hesitation/Surge while in Cruise Control [wrestlingref21] by scheeler Jul 08, 2009 (3:30 pm)
Replying to: wrestlingref21 (Jun 16, 2009 10:38 am) I have the same pickup, the same problem started a few weeks ago for me. I have had it into the shop twice now and they can't find anything wrong with it, seems to cure itself each time I've brought it in. My next call will be the dealer I bought it from even though I have to drive 75 miles, hopefully they will recognize the problem, they are a Dodge dealer. From reading other info online I might try replacing the throttle body sensor before running to the dealer. Good luck! Replies to this message: tlinga (Nov 25, 2009 9:20 pm)
