Question about 2000 Mitsubishi Eclipse

1 Answer

Rough start, smell gas

When I start my car and it is cold, my RPM's jump up and down between 1000 - 2500. When I drive away my car jumps back and forth like crazy. Once it is heated up and my temp is right in the middle, the car runs fine. When at idle, totally steady and runs fine. It only happenes when its cold. Outside of my car, it also smells like a boat. Like it is buring alot of gas. I usually get about 300 miles to the tank. Lately I've been getting about 250. Its a V6 3.0 Stick shift. Please help.

For the RPM's jumping up and down i would replace the throttle position sensor. If it smells like bad gas or rotten eggs these are signs that the cat. converter is going bad. For the poor gas mileage replace the fuel filter.

The chain could jump a tooth or two, but normally a chain or gear breaks. You could pull the spark plugs and check compression to find out.
It sounds like one or two injectors may have failed allowing liquid gas to flow into the cylinders.

Unfortunately, you might have to replace every sensor until the problem goes away. It is a matter of process by elimination. I am in the same position. Good luck

Your automatic choke is probably sticking. Spray it out with 2+2 Carb and Choke Cleaner. Do this when the car is cold so you don't start a fire. While the car is running see what position the choke butterfly is in when the engine is hot. If it is partially closed you may have a bad spring in the choke mechanism or it may need an adjustment.

When starting car the rpms jump up to 2000 then jump down to 500 while feeling like the engine is going to stall out then the rpms go to a normal idle but idles rough for about 5 seconds


its becouse the cars computer tries to heat its self for it not to work when it is too cold
so just leave it there for a while till the rpm go to normal
