Yesterday, while driving on the highway, the SES light came on. Then when I got off the highway and into the city, the car would shake like it was about to die when I started to approach and then stop at a traffic light.

I went to a restaurant for a few hours. Afterwards I go home, the SES light is on, but the problem I had before is gone. Next day I go to autozone and have them pull the code, it shows 1320 which isn't in their system.

I go home, turn the car off for about three hours, unhook the negative terminal. Started the car up and began driving again. SES light wasn't on and the problem I'd experienced before still wasn't occuring.

Now today, I went out and ran some errands, no problems. Then tonight, I start driving and the SES light comes on again and I start having the same shaking when I'm slowing to approach and stop at a red light.

I don't understand it. I put on the Frankencar intake about a month and a half ago without any problems, no SES lights or anything. I checked the hoses attached to the intake, no tears, and checked the intake for any leaks, nothing.

Does anybody have an idea of what the problem could be? Could it be a fuel sensor or something, cuz i'm thinking the shaking is due to fuel not flowing smoothly through the engine. Any help woud be appreciated.

 

This is from the service manual, P1320 ignition signal


On Board Diagnosis Logic
NFEC0288

Malfunction is detected when the ignition signal in the primary circuit
is not sent to ECM during engine cranking or running.

Possible Cause
NFEC0572
I Harness or connectors (The ignition primary circuit is open or
shorted.)
I Power transistor unit built into ignition coil
I Condenser
I Crankshaft position sensor (REF)
I Crankshaft position sensor (REF) circuit

 

manual or auto?

 

its a 2k auto

 

jonbth, thanks for your response. I'm wondering if this is something I can fix or if I need to take it to the stealership.

 

Also, wouldn't this be covered under the powertrain warranty?

 

I think it would be hard to pin down without a diagnostic computer. The dealer might be the best option.

 

"Condenser"... this reminds me of something; Nissan Direct Ignition systems typically use a condenser (capacitor) somewhere in the circuit, anyone know where this is located on the VQ30DE and VQ35DE? I wonder if this could be the cause of any ignition system problems...? (maybe cause the coils to blow easily?)
I forget specifically why it's used... I think it might be used to ground out noise/excessive transient voltages in the primary circuit, but I'm not sure. I got that idea while looking at a schematic for the CA18DE (1988 Nissan Pulsar NX SE), which used an early version of NDIS.
