Ck and clean the maf sensor. It is located in the intake ducting. Get a can of CRC electriccal cleaner spray and wash the sensor as thoroughly as possible. Do not try to remove it from the mounting. Do not rub it, brush it or touch it. It is a very sensitive sensor and just as costly to replace. Do not used compresse air, Just spray wash and let dry. The Mass Air Flow Sensor MAF monitors the intake air density and velocity and tells the computer how much fuel is needed for a proper air fuel ratio mix. This would be your first suspect, Then look to the throttle positioning sensor. This sensor advises the computer of where your foot is. There should be a smooth acceleration if this sensor is ok. No flat spots or stuttering at certain spots. This sensor has to be replaced if faulty.

Runs rough and wants to stall on acceleration also runs rough when ac is turned on


It sounds like you need a complete tune up and filter change on the car/truck. By doing this it should correct your problem. Hope this will help you.

My car dies when i put it in gear or when i come to a stop and a rough idle i changed the tps


Idle air control valve would be my next bet , the TPS usually just makes it rough on acceleration. Is it rough on acceleration(loss of power) ?

Car has the hiccups and rough acceleration!


Go to autozone they have a free OBD 2 code reader. Start by finding out what that code is. It might be something as simple as an O2 sensor. Hope this helps.

Rough idle and acceleration


I am not a mechanic, so I dont know for sure, but it sounds like a problem I had with my car. It turned out there was a bad wire. We serviced the wires and spark plugs and problem solved.

no problem. If you are getting that low of voltage on a load then you might want to test the alternator as well to make sure it is running at capacity.

Poor mechanical transmission or engine acceleration rough


ASE Mechanic here:
Check engine for good tune up, may those spark plugs are fouled out beyond belief, its always best when changing motors to use known good parts....
