Question about 1983 Mitsubishi Starion

1 Answer

I have a 1983 Mitsubishi Starion. I recently purchased it from a neighbor who has let the car been sitting. The fuel hose that connects to the Throttle body has a pin size leak in it and squirts fuel out. I clamped a piece of rubber hose around it to see if i can find what the problem is with the car. The car will run fine if you shift at around 1500-2k rpms. Once it gets above those rpms it starts to shake violently back and forth and acts like will die out if you don't push the clutch in. I'm unsure if it's all because of the fuel hose leak or if it could be the fuel pressure regulator or if it could be a vacuum leak somewhere.

Check air mass flow sensor, with this unit going bad it will make the car runs horrible. also make sure you getting proper fuel pressure with good working fuel regulator. If it has a tubo, check if the turbo charger still working and hook up especially down at the wast gate control vacuum line still hook up to the wast gate control.

Engine idle trouble

that is not a probelem it is the fuel system warming the engine and turbo
you should always warm up a turbo car before jumping in and taking off and cool the engine before shuting it off turbos are the most temprelental engine part there is. those steps will prolong the life of the turbo and engine. my starion with the g54b 2.6 does the same thing
