Question about 1990 Mitsubishi Mighty Max

1 Answer

This truck runs good, the engine is new, new fuel pump, new computer. The problem is after driving for 20 to30 minutes it atarts to lose power, If I turn the key off and let it coast for a few seconds then turn the key back on it runs good for a quarter to a half mile. Then it does the same thing. It is worst in the sunner time, but it doesn' t do it all the time. The other problem is it lacks power at about 65 miles per hr, but if you find that sweet spot in the gas pedal it will eventually get up to speed

2008 cub cadet rzt 50 run for 20 min than dies while mowing put new pump on, new fuel filter, new air cleaner, new plugs. has a 22hp kawasaki engine. fuel lines clear


When it stalls out did you check the spark? I suspect the engine is losing spark due to an ignition system failure.

'06 toyota corolla loses power while driving


The power steering works off the engine, so if engine not running, no power steering. It sounds like to me that a good place to start would be the fuel filter. If the fuel filter is plugged, it may allow enough fuel to go through to run the vehicle for a few minutes but not allow enough through to sustain continued operation. The fuel pump is also a consideration.

1997 sentra wants to stall and has no power after like 20 minutes


Are we "PARTS_NOSING" instead of DIAGNOSING? Sounds to me like you have thrown some pretty expensive parts at this problem....

MANY things can cause an engine to lose power. That is why the problem should be properly diagnosed. If you keep going the way you have been, you could have a whole new car before finding the cause of your problem.

To begin with, your engine is controlled by a computer system that is capable of self-diagnosis. Has anybody scanned the onboard computer for fault codes?

The fuel system can cause an engine to lose power. Has anybody checked the fuel pressure?

A restricted exhaust can cause an engine to lose power (smashed, bent tailpipe, clogged catalytic converter, etc.) Has anyone checked the exhaust system back-pressure?

Nobody online can do much more than GUESS what is causing your problem without some proper diagnosis procedures being performed.

98 Suburban: Loses electrical like a short robbing power to drive


Perhaps alternator is not charging the battery properly 
Test with a voltmeter - fully charged battery should read approx. 12.8 without engine running
With engine running should read 13.8-14.2 .
---------------------
Check the sparkplug wires and make sure the sparkplus are tight 
also check the two basic and very common thinks for this problem.the fuel pump and fuel filter.
if the pump is clogged and filter is dity this can occur.as when ever the fuel gets clogged ,this would make the car stall out and lose power as soon as the engine stopped sucking the fuel due to the debris .
check out this.
thanks,please do rate the solution.thank you for using fixya.keep updated.

Loses of power and engine miss


it may be fuel pump ? how much fuel is in the tank ? these trucks are famous for their fuel pumps overheating when the fuel level gets below half or sometimes evem a quarter tank. if the fuel tank is full you may want consider replaceing the fuel filter (as a good routine maitenance procedure)and see what happens then.

1999 toyota tacoma Sr5 won't start


Check for fuel pressure when starting. Fuel pumps have a check valve in them that keep fuel in the rail at the injectors. If the check valve fails, the pump has to pump fuel all of the way up to the engine. Same thing with hot no-restarts. Fuel pump.
