I checked all the fuses and some were burnt so I replaced them with the factory recommended types. Then when I turned on my headlights only the high beams would work, so I rechecked the fuses and the headlight one was burnt out. I replaced it again and the lights went out once more. I put in 15a instead of a 10a and everything seems fine, but my dash never came back on.

I recently put in a car stereo and I was having trouble with getting it to stay on, but that turned out to be a ground issue.

I bought a rear caliper seal kit from an autoparts store, for my 1987 Nissan 300zx 3.0l non-turbo. The caliper had some broken parts within the piston which look like o-ring bearings and a c-clip.

1995 300zx both low beams won't come on just started last night all other lights work, relay is good swapped with alarm relay to check and no fuses are blown. Have owned the car 4 years with no problems like this.

I've had this problem for several weeks now. Car feels like it has a constant miss throughout the rev range. I have just done a plenum pull, installed new injectors, replaced injector and coil connectors, new temp sensor and cleaned the throttle bodies as I had planned to do this - no difference. I ran ECU diagnostics with code 55 recorded with engine off - everything OK. With engine on recorded left side O2 sensor is faulty.
I also checked the voltage on the MAF and got a reading of 0.48 volts with key on (spec 0.8V). With the engine running the reading was within spec at 1.29 volts. I cleaned the MAF with MAF Cleaner and also cleaned connectors and terminals. Re-tested - no difference in values.
Voltage on Throttle Position Senser OK at both connectors - spec in the manual states approximate values for a couple of wires - only discrepancy I got was 0.86V wher it states approx 1V.
Also timing belt etc was replaced and has done approx 50,000Km (half way throuigh its life cycle).
I am planning to change the O2 sensor this weekend, easier said than done.
Any help with this issue would be appreciated as I am becoming frustrated - do the figures recorded mean I need to replace anything.

I have a 1994 Nissan 300zx non-turbo.I just had a fuel injector replaced on my 3rd cylinder. 3 days later after my car was sitting for about 7 hours i started my car an it was making really weird noises when i pressed on the gas. I then noticed that i lot of white smoke was coming from 1 of my tail pipes(i have 4) I turned the car off and i noticed that some type of fluid was leaking from the pipe where the smoke was coming from. Inside that pipe there was alot of black sludge. What could this be? Please help.
