I have a mitsubishi triton 2012 when it gets to running temperature it starts to lack acceleration and starts to stutter, how can i fix this?

are you asking for the specs for valve adjustment

if it gets louder the harder you go then check for a faulty cat converter blocking the exhaust system

One way is to remove the tank. You may also siphon the fuel out with a siphon hose and pump. Usually you can get this at your local Auto Parts store.

ENGINE HESITATES WHILE ACCELERATION

LOSS OF ACCELERATION

It can be fuel pressure issue or it's the problem with accelerator pedal or its clogged filters causing there.

There are many other possibilities. I suggest you to go through the list of help links mentioned below, these will help you to confirm where the actual fault lies: -------

You need to run a fault code test on the electronic engine control module. You can learn how to do that here

The engine management system has been alerted by one or more sensors of a malfunction and that has caused it to turn the service light on. It could be a number of things that caused it, but without knowing why, we would only be guessing. You need to have an OBD II diagnostic scan run on your Galant to determine what DTC codes have been set by the engine computer. If you can do that, and report back here with the code numbers i will continue to help, but we need those codes.

A typical code will be 2-3 letters letters followed by 2-3 numbers.... P0401 for example.

Replace o2 sensor and ECU might need an software update done by ur local dealer.Post by AUTOMOTIVE DIAGNOSTIC FIELD SERVICE South Africa

full power is only achieved when the engine is fully warm(operating temp).so if you accelerate more than, say, a third of the gas pedal,the car will feel sluggish.
this is more apparent when first starting the car in the morning in winter.almost like the car is going to stall.
most wear in the engine is leaving it to idle when cold you should always drive the car straight away from cold.then when hot turn on the a/c if required....

4.2 ltr missing. 2000 truck, f150. Changed plugs, wires. Ran great for 2 weeks. Started again. Changed coils. Got worse. Changed fuel filter, did nothing. Added injector cleaner and fuel cleaner, nothing. Checked EGR, o.k. It is getting worse. Had new gas about the time it all started.
