Asked by Apr 30, 2016 at 12:56 AM about the 1999 Mitsubishi Galant LS V6

Question type: Maintenance & Repair

Ok so first was low idle ect so I replaced iac and
distributor plugs and wires all 6 as I don't think the
firewall side had ever been replaced and cat
cleaned maf and throttle body now idles high
2000rpm so it went from the low idle blues to high
idle I can't figure this thing out also while it was
running I sprayed everything with carb cleaner and
when that ran out starter fluid to check for vacuum
leaks nothing no codes either but srs light did trip
after I pulled the upper intake manifold but I don't
think it was that probably just from the battery
being unplugged I checked o2's both looked good
wasn't really even rusty or covered in carbon this
thing is a pain anybody got any ideas ?

...sounds like you got it covered, my friend...one thing is the Battery...will stop accepting a charge after 10 years...and will put out reduced performance after only a couple of years...would think about the main 30 amp cable going to the chassis...and the one to the engine block as well...over time will get corroded....wirebrush clean~ with renewed power things will begin to act properly....like sensors and the ECU~
