Hey guys im new here. just bought my G35 3 weeks ago and now can't drive it. It has 107k. So it was driving fine and then i lost all throttle. then it would come on and off sporadically. when in park or neutral the rpms will jump when i hit the gas but not in drive. abs vdc and slip lights are on when this happens. car will not always start right away after turning it off. had to jump it last night. noticed battery terminals arent on very tight but they wont tighten any more. need new terminals. But what else could cause this. could it just be my battery or alternator? i have a bad belt or pulley which squeaks so maybe its slipping and not charging properly? Before everyone says it i know i need to get it scanned im just unable to do so at the moment. Therefore i don't know what codes it may be throwing. Thanks for any help

 

You can order an ELM327 to be shipped to your doorstep for 15$. Buy the torque/dashcommand app for your phone and you can scan obd2 trouble codes for life.

My other thought is camshaft sensors or the crankshaft sensor. Autozone sells all these replacement parts.

 

thanks for the input. turned out to just be the alternator
