A lot of Nissan's are having this problem especially the Z's and the Infinity G35. A few people have reported changing their PCV valve which will be in the top of your valve cover and goes to the intake.
Mechanics report that there are 2 oxygen sensors after the cat converter that it could be, and also run a bottle of Sea Foam through to clean your injectors. You will still have to go to Advance or Auto Zone to have it reset, but either way I would try the Sea Foam and the PCV valve first since thats really easy.
sea foam ?? what is this please never heard of it before ,anyway have checked out the autochoke device ,their should be a sensor on the cylinder head thats is a temperature gauge and it turns on the autochoke and this circuit has a problem but as to exactly what is the problem i couldnt say without a detailed inspection
hello, also check plug wires,distributator, cap and rotor button, you can check plug wires,at knight time, crank engine, with hood up, walk around car, look at plug wires while motor is running, see if any sparks are coming from plug wires, also if it clunks, like you said, you may have broke motor mount, transmission mount, check for air lines leaking also
there might be a problem in your fuel line. try buying a can of sea foam [Red and white bottle.Available at any auto place. Around $9]. pouring about half in the tank and the other half thru a line in your brake booster or another vacuum line. the line will be under the hood to the very top right. it should be black, round, and two lines coming out of it. do this with the car running so maybe have someone else hold the gas to about 1500 RPM. Slowly drip the sea foam in until it almost dies then put your thumb on the line to keep it running. keep doing that until the can is almost or fully empty. Let the car sit for about 5 mionutes then start the car and keep the RPMs to about 2 grand. There will be smoke fromt the exhaust SO DONT WORRY! Just keep on the gas until the smokes clears. If that doesnt help let me know!
Everyone is guessing. If they do know the answer they're not telling because it's a B- - - H to get to. It's your IAC valve or idle air control valve and it's located underneath the intake manifold. The part might cost $40 but labor is a different story. Good luck.
It sounds like a clogged catalytic converter. If you can unbolt it; try unbolted it and see how it runs. Also try unplugging the sparkplug wire one at a time and see if the shaking gets worse or stays the same. When you pull a spark plug wire and the car stops shaking then that cylinder isn't firing. Watch out though, you'll get a nasty shock if you do it without insulated pliers. It could be a stuck valve or bad ignition.
Your EGR valve shouldn't open up during idle or the engine will run rough and may even stall. Remove it and clean the plunger and port with a wire brush and some carb cleaner. Test the diaphragm with a vacuum pump. If it doesn't work after cleaning, or the diaphragm is bad, buy a new EGR valve.
you don't have to pull off the intake manifold. take the egr off and clean the port is all. then the code has to be cleared.the egr is on the right side of intake(closest to the firewall. you can use a small wire brush or old toothbrush to do this. also check the wires and plug and if you egr valve has a vaccum line make sure it's not plugged loose or missing. use a lil bit of carb cleaner to clean port. replace egr and clear the code a scan tool will clear this code. please rate this thanks
