see what I mean? V6 means nothing, for sure lacking a year.

check fuel filter,or fuel injectors, fuel pressure regulator.Also check fuel filler cap.Check exhaust system for plugged catalytic converter,muffler,bent exhaust pipes,etc.

If by flat spot you mean "hesitation" , you need to check the status of fuel filter, air filter and fuel pump. Inspect your spark plugs also as a precaution to eliminate them as the culprit.

Hello! Is the engine an RB or a VE30DE? The code is stamped on the block...From my experience the 1994 Cefiro only came with a straight 6 rather than a V-6...Can you specifically identify the engine? Also does it have two timing chains; An upper and a lower? Thanks .....Guru...Saailer

the steering wheel gets stiff, because the car died and your power steering pump is stopped. beeing a 1994, you may have a fuel pump issue (nissan had campaign on those), but most likely no longer available to you, because of the age of the car. they purge campaigns out as years go on. you could have an issue with distributor. oil leaks pass the seal and gets inside of the distributor assembly on the signal plate (internal component of distribitor) and messes with the ignition system/spark plugs. you may also have a broken intake gasket. When was the last time you did a tune up?? changed plugs, fuel filter and so on???

check your owners manuel..if you have none than purchase one.
I would say leave them alone .

The first thing i'd tell you is to not run the engine at all before fixing this if possible. Diesel fuel doesn't burn very good in a gasoline engine, if at all... There is not enough compression in a gas engine to get the diesel hot enough to burn, even with a spark plug.

There is a few ways to go about this but the easiest one is to find and disconnect the line coming from the gas tank to the engine, as close to the fuel pump as possible (preferably before the filter) and route it to an empty container, then jump 12V to the fuel pump motor terminals, or jump the fuel pump relay terminals (to get the pump running) and let it pump the diesel fuel out in the container...

As a precaution I'd change the fuel filter after this, fill the tank back up with clean gasoline, and give the car a good run... You can expect the engine to smoke and run bad for a little while, as there will still be a little diesel going through.

As for the cost to get it done, I really couldn't give you a straight answer... They could do it like I said or another way (drop the gas tank...) It's not that hard to do if you do it yourself or find someone you know who can do it or a good "backyard" mechanic, but I'm sure some of the shops out there could write up a nice repair bill for this...

It takes unleaded regular gasoline. I'm assuming by water you mean coolant. check the overflow container if it has one, should have lines on it for hot engine and cold engine. Standard oil changes on most cars, if using regular oil, is 3 months/3,000 miles. depending on driving conditions.

Ck your cap .

Turn eng. off sprary with water , wait 3 min. start it up.

Look to see if spark is jumping across to top.

If so change cap , If not ck, for oil inside cap.
