After bleeding my clutch while in the air on jack stands I raised the car in the air to see if my gears would Engage and wheels would spin. When in 1st gear the engine shook and my wheels barely spinned and stoped. Can this mean I installed it incorrectly ? Also to note I've read when In the air to turn off VCD , can that be the reason why my wheels won't spin properly or can the reason be because my pilot bushing was installed wrong ? Please let me know

The problem occurs every 2-3 weeks

My engine builder has had two new engines fail, one with 580miles, the other with 1860miles, and is warrantying the second engine but is telling me that my cats are bad and led to this second engine failure. I told them that I suspected that the first engine's bolts were overtorqued (cam seals and valve cover seals leaked from the start, at 580miles the rod bearings were so ground down that the oil filter was full of metal shavings, not to mention it never ran quite right. When the second engine failed, I suggested that they didn't flush out the oil cooler, or replace it, which led to the failure. After two weeks of inspection as to the cause, my mechanic is having me replace the oil cooler and the builder is saying the catalytic converters are bad and caused the failure. The car passed emissions three months ago, before the OE engine failure and all this nonsense. Having said all of that, I've had cats fail before to where they were so clogged the engine wouldn't run, but it caused no permenant engine damage. I've never heard of bad catalytic converters causing engine damage and I used to build race engines for a race car shop, have worked at other independent shops and I studied cars for three years in Auto VoTech classes during high school and received an AA from WyoTech. So I'm just curious if anybody has heard anything like this relating to the G35 specifically.

I can drive for miles with my blinker on. I used to get a warning sound, reminding me to turn it off. Is there a way to correct yhis?

Hello. I have a problem with my audio in Infiniti G35x 2004 sedan. First of all it doesent find any radio station, it keep on seeking without ending. I dont know about tape but CD is the only thing thats working but still not as it suppose to. The CD starts working after i switch ignition but the audio quality is terrible, it gets better after starting the engine. But thats not everything, the audio quality gets really bad randomly, sometimes it is like that from the beggining, sometimes it gets bad after the car makes a little hop or when i touch it, but it also happen just by itself. It gets better after I tap or punch the radio panel. I triend to dissemby and put it back into one piece, i checked the wires but it didnt help. The wierd thing I found out is that my voltage meter shows a little voltage on the radio casing and a little bit on the car body. The car was a bit damaged in the rear so the window could be replaced, I bought it like that so i dont know what was done, and as far as I know the antenna is located in the rear window.
Does anyone know what can be the issue?
Do you guy have a diagram where the antenna wire goes? I would also be grateful for a diagram with all the radio plus wires voltage sa I could chcech if everyting is alright over there.

Is they any problems with the car I should kno about before I buy it

why did this car completly shut down and will not start

You only notice the loud noise when the A/C is on.
