| Subject: | Mitsi Galant Viento spluttering |
| Question: | I have a 1990 Mitsubishi
Galant Viento DOHC Automatic. Has been purring like a kitten
for 5 years with regular maintenence. Has developed a sputtering
under 3000 rpm during acceleration after adding STP Fuel additive
to a full tank to clean jets. Have replaced spark plugs which
has restored a large portion of power during take off. This has
improved the problem when the car is cold but still sputters
when hot when accelerating. Have also noticed the trans a bit
jumpy between 3rd and OD and has not been able to mesh into 4th
from 3rd (ends up in a neutral) when going up a reasonable incline
at speed (has done this once or twice). Trans fuid is clean and
full. Any help would be appreciated. |
| Answer: | Simon, The early model Galants are notorious for having sticky transmissions. And with your particular year, it may be an electrical problem. Take a look at this article. Even if it does not apply to your problem, its good to know: http://90gsx.com/eclipse/cap/caps.htm Have your ECU checked along with these other presumable causes: These possible causes are taken directly from the factory service
manual. Have your car inspected at a transmission specialty shop.
Your average mechanics garage may not have the knowledge set or tools
to handle this job. Plus, it will probably be less expensive than
going to the dealership. But whether you take your car straight to
the dealership or a transmission specialist, bring the list of causes
I mentioned. They will most likely be impressed and not over charge
