no check engine light on, yes it is all the time. is ecm/tcm or pcm a common issue with these? from past encounters the computer is not usually the problem. and one of the more $ parts

Most often I have found the engine light on because of gas tank vent, such as loose
or bad gas cap or the vent valve stuck open. The computer does a cycle ever so often
and maintains the vent pressure build up in the gas tank and vapor canister, and if the purge valve sticks open the computer gives a check engine light and code as the pressure is not in the vapor storage tank when called for.
I would say you have a bad gas cap or open purge valve or a leak in a line or the stowage canister.
You may try taking a battery cable off and turn the key on in order to reset the computer, but if the light goes out it will come back when the computer does a cycle
if the vapor pressure is not there,

The ECM (Electronic Control Module) is a common problem with this generation Quest. The placement of the ECM makes it susceptible to excessive moisture and corrosion. It does cause problems that may lead you to believe it is fuel related since it does control many of these functions. The ECM is expensive but is covered by the 8 yr/80,000 mile emission warranty.
Since there is no "check engine" light, the best thing you can do is have a mechanic troubleshoot the problem. I would have the mechanic scan for codes event though the CEL is not on. Make sure they are aware that it happens all the time. A good mechanic should be able to isolate the problem. let us know how it ends up.
#72 of 164 1996 Villager 3.0 L rough idle
Jan 21, 2010 (5:07 pm)
I have read many posts regarding the distributor and rough idle. Most refer to the '99 year which has the internal module. Mine is external, as is the coil. My problem has not gotten better after changing plugs, cap, rotor, IAC, wires, cleaning the MAF. After warming up it will chug in park, you can feel that the exhaust is not coming out smooth, and stumble/lurch forward at stop lights. I have looked at the dist photo eye which looked clean. How can I tell for sure it is the distributor. The CEL is not "on". It has good acceleration and does not die while driving. Has anyone else solved this problem on the 93-98 model years? '99 model year went to a 3.3 L engine.

Jan 22, 2010 (9:05 am)
Ok so I have a 94 quest. I am poor and this is only vehicle... Firts problem was water pump and thermostat. changed replaced both. no more overheating. 2wks later drove vehicle 100miles, gave it an oil change and plug change, ran nice. out of nowhere after an appointment she refused to start. had to get a local mechanic to tow and repair. 300 bucks later a new fuel pump was installed, and the crank but will not start prob fixed. or so I thought. 2 days later while driving she just started bogging down and shut off on a hill. as if starved for gas. cranks but no start. towed to friends house. we then changed fuel filter thinking clogged. Nope. cranks but no start. next up was fuel relay on injecter rail, changed that. No start. pulled hose from top of filter, flow SEEMS ok, no tool to test presure. squirted ALOT when key turned on fuel pump. left car sit. put a battery in that was laying around and just for the heck of it tried turning over, and vrooom she turned, but died shortly after running her, 3-5 minutes, as soon as it hit a little incline. vehicle is now stuck again I need HELP please. also where is the OBD port on this ahem vehicle? Thanx

Replying to my original post. I took my van to a Nissan dealer. They claimed it was my injectors reading out of range, some high - some low when warmed up. All six were replaced. Van has run fine for 2 weeks. I hope they were right.

Your Distributor just maybe your problem if you have high miles. The bearing on the Distributor shaft gets dry of lubricant with age and miles and as the engine runs the
Distributor gets hot and you will get this code.
Before spending any money I would check and replace the Distributor. You can buy one off EBay for less than $150.00.
Also if you read the posts on the Villager and Nissan Quest you will find it helpful.
