Check timing belt to be properly line up to the markings or take it to someone who knows about this cars to check if its lined up ,I had a similar situation and it was out of timing and it started to not rev to the max and being very lazy on going up hills or just going up.

Run the fault codes as what you have done may have no impact on the fault

1993 Mitsubishi 3000gt when mass air flow sensor is plugged in car wont rev past 2500 rpm car was bought with it unplugged. Replaced the mass air flow sensor an still does it. When its unplugged it runs...

The computer only knows the voltage across what it thinks is the MAS. A bad wiring connector and a bad MAS is all the same to the computer. I would change the harness to the MAS before I spent any time or money on any other problem solving.

What would cause spluttering when raving car

Most cars have a rev limiter between 2000 and 3000 rpms when transmission is in park. Sputtering in gear could be bad plugs, dirty throttle body, dirty Mass Air Flow, bad Coil on Plug.(COP) Clean throttle body, clean Mass Air Flow sensor, remove and inspect plugs, replace if over 50,000 miles. Inspect all COPs for cracks. Use code reader to isolate fault or faults.

Code P1102 - States pending fault.

P1102 for the Mazda is :Mass Airflow Sensor Signal Inconsistent with Throttle Position Sensor. The Mass Airflow Sensor is located in the housing before the Throttle body; it reads the air coming into the system....the Throttle Position Sensor tell the ECU how much throttle you are asking for....I think that the in-air flow and the throttle are not getting the same answer; example would be that you are driving fifty miles an hour and either the MAS or the TPS are not seeing (receiving) this information. Note; most times the MAS is at fault, it can be cleaned but be very careful.

I have a 2002 Mitsubishi Galant and in lower RPM it wants to chug and hesitate a little but in high RPM it drives fine. The ****** shifts smooth so I don't think its that but Im not sure what else

The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS COMPLETED.

2000 linclon ls with no codes sputters upon accleration

mass air flow sensor or the throttle body needs to be cleaned .first take the intake hose of the throttle body and spray the inside the the throttle body with throttle body spray. there is a pin hole under the flap or the butterfly that lets a little air in make sure that is allso cleaned out. let it sit and see if that fixes it. if not (MAS )sensor would be my next guess.

Has bad hesatation when tacking off like its not geting fuel

Try unplugging the mas air flow sensor.This is located in the air duct that goes from the air filter to the throttle body.If it takes off normal when unplugged then get some mass air flow sensor cleaner and remove and clean the sensor and let it air dry.You can find cleaner at most part stores.This should take care of your problem.Let me know.Good luck.

Hard start when air temp is cold, backfires when warm

Try this, remove (MAF) Mas Air Flow sensor,(be sure key is OFF) so you don't set a trouble code when disconecting wire conector, with some throttle body/air intake cleaner from the outlet side of MAF, spray the sensor clean, let dry, reassemble.Remove snorkle from throttle body, and with a old tooth brush, clean throttle body& plate with cleaner, may take a couple of cans if throttle is badly 'coked' up. Hope this helps.

Idle surging chugging weird problem READ!!

hey common problem w/the 2000 galant. you may need a mirror to see this, look and or feel where your throttle body mates up to your intake manifold. it has a problem of cracking, when you have an air leak there it will run like **** and usually shut off depending on the severity. this will cause you to get the throttle position malfunction code. if that is the case instead of buying a new or used intake manifold. take the old one off, and you can actually cut it flush and weld about a 2 inch in length tube to repair the crack. well let me know how it goes.

Hi,verify throttle cable is ok and connection at throttle body is good.If cable is ok,you need to do diagnostics on the computer..Every thing is speculation without data from computer.But i would check the throttle position sensor and the mass air flow sensor.Sometimes the maf sensors elements get dirty and cant read the correct amount of air flow entering engine.If this is the case,you can clean the elements with brake clean...Good Luck!!!
