Question about Mitsubishi Cars & Trucks
Engine# 4G64 AM4623
Possible causes are:
* if you have a distributor, the spark coil assembly in its base is faulty.
* Timing is off. Check the belt at TDC and ensure the cam markers line up.
* check the coolant temp sensor on the thermostat housing. If the wires are damaged (common for older cars) the ECU cannot work out the spark timing properly.

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. There are test that need to be performed the find out the cause. The light will stay on until the problem is solved.

Hi, I have a Mitsubishi Chariot Grandis Exceed 1998 (4g64) and recently changed the engine. Prior to changing the engine the car had a shudder when driving approximately 70kmph. This appears to be caused by some sort of misfire as one can see the ref counter dropping and picking up slowly. After changing the engine I still have exactly the same problem which tells me it is not the engine. I took it in and they tested it with one of those plug in machines but to no avail as it did not pick up any faults. Due to the slight drop of the needle prior to the car shuddering, I cleaned out the injectors but this does not appear to be a part of the problem. This usually occurs more often when the engine is warmer and not when one start up and drive. Any ideas what can cause this?

Hello and welcome to FixYa!
This can lead to many things, most of all is because of a bad sensor. There can be a bad sensor somewhere and I strongly suggest that you have the engine scanned. During the diagnostic it will list the trouble codes and by then you'll know what part is in need of replacement.
Although in my own opinion, it can be a possible MAF (mass air flow) sensor issue. If the MAF is faulty there will be vacuum irregularities.
Hope this helps and thank you for using FixYa! Have a good one!
