    OK, That knocking is the Pistons. Pretty Quick you are gonna have to Rebuild that Motor. Until then try and keep the Oil just a Tiny bit about the Full line.

Why does my 420a 96 eclipse idle high at 2k and after running It goes up 4k idle? It has a miss fire and smells of gas when running. I have trouble codes p1294, p0443, p0340 any suggestion?

p0340 is the cam sensor, 0443 is the purge solenoid, 1249 is the wastegate on the turbo. The smell could be from 0443, it might be the solenoid on the evaporative system is bad or stuck, the cam error could be the sensor, wiring or the cam itself and the wastegate is the part of the turbo that dumps the excess compressed air that the engine does not need.

Swapped a 1999 420A engine into a 1995 eclipse (also a 420A) and we have no spark. We started by checking the cam sensor and it is working properly it is upside down from the 95 but the ASD relay is...

first the cam sensor shouldn't be upside down from the 95. they both should be with the plug facing down. they 95 CAS has a different plug than the 99 CAS.
the 95 has round pins and the 99 has flat pins.

also the 95-96 relays are opposite the 97-99

besides that it could be the ecu. i also have heard of the locating pin on the intake cam shearing off, allowing the gear to turn with the timing belt without the actual camshaft spinning.

Since you didn't specify if you had the turbo or non-turbo engine, i'll give you links to both.

How do i remove the starter from a 1997 mitsubishi

mitsubishi offered several different motors, if you have a 4G63 or 4G64 (spyder), it is under the intake manifold, you will need to remove the battery to make it easier.
If you have the dodge 420a motor, I don't know off the top of my head

Motor swap

If your planing on swaping the 2.0 non-turbo(420a) to the 2.0 turbo(4g63t) your problem will be that the motor and transmission are on opposite side of one another. My GST has the trans on the passenger side and the motor on the driver. The 420a is just the opposite. If your serious about it you should get the motor rebuilt with higher performance crank, pistons, rods, exc.  And they make turbo kits for the 420a.  But you'll need better fuel delivery and some mild tuning.
