yes im crying right now. heres the gest i bought this car a month ago.. its a 1990 300zx n/a 5 speed with cuise contol and the works. when it was new who ever bougt it must have got the full package except the tt , wich is wat i eventually want to do. this time i ever learned about this car i rebuilt one from the round up on jack stands for a friend. i fell in love instantly

so i paid 1300 for it. i drove it home non oped with bald tires no brakes no clutch, barley any winshield wipers lol and its been in the shop since getting a clutch,rear main seal, and frezz plugs. i ve only drove it a few time since then. they hevent got the clutch right at all the last three attempts and now after almost dying in it because they tight the master cylinder too much it was slipping while driving.

anyways i bought the best spark plugs you could buy in between shop visits i put them in and changed the oil clead the maf sensor with maf cleaner. when i got it back the first time they didnt bolt the exhaust back on all the way it had an inch gap and the clutch was way wrong.

i took it back the changed the master cyclinder again and said that fixed it, wich it seemed to. but my engine light came on then i took it back and as of today they said it was a ground wire and fix the engine light coming on.
but before i took it back tis last time when it did pop it was code 52 54 and it seemed my right o2 sensor wasnt blinking like it should on the ecu test. i pick it up today because the mechanic basically told me my cats were bad

when he did the pre smog it read i dont know what to do so lost ......
so depressed..... this is my fav car in the world..........
