Had timing checked .. its @ 16 deg- but the it pulled a code 33 and 53 / no voltage to 02 sensors.
Are there typical trouble spots in connectors / wiring? I don't want to spend hours in a shop to diagnose.
O2 sensors don’t normally have frayed wiring issues. Could be a mouse that chewed through something? Do a visual inspection of the o2 wiring runs...shouldn’t be hard on the passenger side. Driver side will be more of an issue.
It’s also possible an o2 just failed? Always a fun time getting the rusted threads to unscrew out...
Ok, replaced both O2 sensors (they were really old anyways) and it seems to have more power -- however, I am still getting some knock at times, it's very unpredictable though,, I can hear a faint "rattle" in OD at low rpms. I also have some lifter noise upon cold startup which may be related?
Which direction should I pursue now?
Ps , engine has only 109K on it so it's not exactly high miles.
My back up light does not work. Many years ago I had the transmission down to do a clutch job. Determining that the switch was bad (jumper the plug) I replaced it. However I replaced it with an aftermarket switch and it does not work. It needs more "throw" in order to engage the circuit. The Z...
Hi everyone, I have converted my 1990 300zx 2+2 to LEDs (mostly). There have been a couple issues since however.
#1 . The red 'Lights' warning light on the dash comes on when braking. I'll try to post a pic.
#2 . The trunk light flashes quickly when closing the driver's side door.
#3 . The...
I have owned my Z for 15+ years, and this is a first time she has left me stranded. Well there was that time the starter fell out of the transmission but I pushed started it and drove it home.
Cold last night. This morning the temp was 10 when I got into the car. Didn't drive it all this...
