I'm feeling a slight vibration at idle and the car is feeling a little sluggish on accelaration. Also, when on WOT, the check engine light flashes on and off.
The CEL has been on for O2 Sensors for a couple of years and has never flashed.
What led up to this was that I was running out of gas and waited a little longer then usual to put gas in. I filled her up and put in 17.034 gallons. The first time ever I got into the 17s.
Did I screw up my fuel injectors? Should I put some fuel injector cleaner in there. Any suggestions?

BTW, its a 99SE with 131,500 miles and she was running perfect up to this morning.

 

Hey Jude,

Did you try and check if you have any other codes stored in the ECU? Scan the ECU and see what you got there. LMK

 

Hey Luke,
Didn't get a chance to, I have the reader at home. I'll run it when I get home.

BTW, wifey finally replaced her wrecked 06 WRX, we picked up a 97 I30 with 94k miles for $3300.

 

i thought a flashing CEL meant misfire???

 

Looks like you are right. I went to an auto parts place during lunch and they read the code. Its coming back as Cylinder 4 misfire.
I just changed all six coil packs in the last year, this is ridiculous.

 

Where is four located anyways?

 

if im correct the cylinders are as follow

(firewall)
1 3 5
2 4 6
(front)

I found this while searching http://forums.maxima.org/4th-generat...1-misfire.html
see post #6. he has a good idea about switching coil packs from another cylinder and see if you get the same or not.

 

Awesome deal on the I30, and yes if I remember correctly a flashing CEL indicates misfiring.

 

yep it does

 

i hear that sometimes fuel pump gets messed up if let run dry or close to dry but not sure if its your problem. might want to take a look though

 

When the coil pack on cylinder 4 was changed, the connector was britle and broke while being removed. I put it back together as best I can and the car ran fine. its too much of a concidence that now that same cylinder is misfiring. I went to Nissan to see about buying the connector and they said that its not sold seperately and I would have to buy the whole wiring harness.

 

You could always go to a junkyard. I think I have some spare connectors around here, let me know if you need one.
