Idle problem with 93 Maxima

[PopPop]

Started to smell gas a few days ago in interior of the car but when under eng. compartment no smell. Sometimes these have the bad fuel hoses like the G50's do and crack and needs replacing. Car idle starts to go from 700 to 2000 RPM at times but settles back to where it suppose to be after that. I checked TPS and IAC and Maf all good. Next step might be fuel since I smell this at times and maybe EGR System. All help will be appreciated and no codes/ check engine light

yeah if it smells like gas, the fuel lines are probably beginning to crack and let fuel out. Remember to use fuel lines that are meant for fuel injection (high pressure lines) instead of carb'ed fuel lines (low pressure) when you're doing the change over. It's a cheap thing to fix and probably needs it by now. Remember to get the fuel lines at the fuel tank as well. If you're back there, it might be a good idea to replace the o-ring at the fuel pump sender unit to the fuel tank as well.

Your right about the fuel line a lot of people will use the normal non fuel injected line that wasn't meant for HP injection systems especiallywhen they tell U the price on it. Goodyear makes a good injection line.
