Diagnostic codes for a mitsubishi eclipse 2001 v6 p00100. mean

Usually happens when oil gets through the rings to the pistons. Might need engine rebuilt but fast and temporary solution is that smoke be gone stuff you can find in stores

no it would only have to do with idle

that code is for the MAF sensor , firstly clear the code and test drive and see if there is any improvement , if not then change the MAF sensor located on the inlet manifold

Misfires are set because one of three things is wrong or missing: spark, gas, or compression. One of those is compromised to set a misfire. You just have to isolate the problem. It sounds like your engine is missing pretty consistently.
I would start with a fuel pressure test (checking the fuel pump and fuel filter). If pressure is correct, check for any air leaks around the intake manifold-the wrong fuel/air mixture in the cylinders can cause misfires.
You indicate it hesitates more after warmed up. You might try comparing the spark from each cylinder after the engine has reached normal operating temperature. It is a tedious process pulling each plug wire off the plug and then have someone crank the engine over. But you might notice a weaker spark from one or more? You would want to see a strong blue spark from each plug wire. Then you could be pretty sure the ignition system for spark is okay.
If you still haven't found it, it is time to do a compression test of the engine. You would expect all cylinders to have pretty even and balanced compression. That means full power and no hesitation, no missing. The ECU sets a misfire code because it senses the lag in crankshaft rotation-one or more cylinders is not producing the expected power output. So there's a map for you: gas, spark, or compression- which one is your engine missing.

You must do a fault code test, anytime the check engine light comes on a fault code is set in the computer control units memory. To do this test without any special tools follow the instructions at the link below.

Hello! The Top Dead Center Sensor is the most likely culprit...However, it is not sold as a separate item and is part of the distributor...The cost of which is $350...I would suggest having the vehicle hooked up to a diagnostic machine to be certain...A diagnostic check should be under a $100...See distributor picture below...

drop the tranny and it will be right there

Assuming you have a V6 yea the upper intake has to be raised up. The book time is 2 hours. I guess I would say the job is semi easy.

yes this affects the emissions coming out of exhaust sytstem it really does choking the engine..also check the coil packs if you have any
