Nissan Truck XE -- engine problem..please help

I have a 1994 (built April '94) Nissan Pickup XE (4 cyclinders). A few years back the check engine light was on but it still drives...so I ignored it. Now the check engine light is not on anymore (I think it burned out). But the car is getting "rough". Gas milage is terrible now and occassionally at stop sign, it vibrates and feel like it's going to die on me....very violent shake.

I'm thinking it's the oxygen sensor (car has around 150K miles now). Is there anyway to check what's wrong with the car to be sure???

Check the sticky at the top of this forum (Truck/SUV) titled "Friendly message from your moderator" and follow the instructions for pulling the codes from your computer. Do not randomly replace parts until you can properly diagnose the problem. "Shotgunning" parts at it will likely only cost you more money and may not solve the problem.

They're on the actual computer unit. On my truck, they're facing the transmission tunnel (as is the small dial), making removal of the seat necessary.

OK, found the darn thing under the PASSENGER SEAT, no that was not the first place I looked.

It has a little dial on the side but no LED's that I could find anywhere! Must be different on the 96. Oh, well, maybe I'll go to Autozone and see if they can do it.

On a positive note, I did locate a french fry that had been missing for some time.

Amazing what you'll find under the seat. I learned things about the previous driver of my truck that I didn't really want to know... liked to clean his ears while driving... liked extra mustard on whatever he ate from Burger King... etc.

The LED will be recessed in the ECU a little. On most Nissans the Check Engine light on the dash flashes with the LED. Might be a good time to replace the dash bulb. Does it come on with the others in the self-test when you first turn the key to the "on" position?

No LED anywhere on the thing on my 96, I looked hard. I think this truck has what's called OBD 2, needs external reader. Check engine bulb is good, light is on steady. I disconnected the batt overnight and got one 5 mile trip with no light, then on next start up it came back on. I'm off to Autozone to get the code read.

the previous driver of my truck liked to pick at his teeth with toothpicks..found half a million of them in my truck! (the person also must've loved chocolate milk..because found a bunch of the things that you rip off so you can take the lid off of the bottle and a bunch of the lids!) WOW! (bunch of french fries, and a rope where the car jack is under one of the back seats!

i have also never seen these LED lights under the seats..how is the easiest way take out the seats in the 95 Pickup XE king cab?? because i have misplaced a couple of things..my CLIE for starters.. and the last place i saw it was in my truck and now i can't find it anywhere! oh well!

If it isn't a Nissan..you paid too much! :jump:

The seats are bolted in. To remove them, unbolt them. The LEDs are on the inboard side of the ECM (where the screw dial is). Apparently not on the OBD-II vehicles, but it will be on a '95.

theres a cheasy black plastic shroud that covers the ECU in my 96. It makes it nearly impossible to see the lights. You practically have to remove the seat to see them.
