Have you ever been in a situation when you are about to rush to a hospital and your car almost gives up?

The common problems of used cars are often mechanical issues. Those issues could be passed on from the previous owner. In case such issues appear when you are driving the car, you have no other option than taking the car to its authorized service center.

The technicians use computers to detect the DTCs (Diagnostic Trouble Codes) to identify the issue and mend them.

The problems of acceleration and pickup could be a little complicated. The error may not be recorded in the DTC and the technician may need to conduct a thorough manual inspection to find out the fault.

These hassles can be avoided. If the buyer can decide about buying a used car based on Reports on Vehicle History generated by the CarCheck feature of AutoHealth.

Common Acceleration And Pick-Up Problems in Cars

Common acceleration problems may not be detected by the Electronic Control Unit (ECU) of the car. In this scenario, the scanner plugged into the On-Board Diagnostic - II (OBD-II) of the car may not show any Diagnostic Trouble Codes (DTC). The technician may need to find the issue through a time consuming manual process.

Reasons :- There can be a few reasons that can affect the acceleration and pick-up of a car. They can be listed as follows:

Fuel System Issues - A few types of fuel system issues can be listed as the followings-

• Clogged Fuel Filter/ Pump
• Dirty Fuel Inejectors

Inadequate fuel delivery diminishes the acceleration, often at high speed. Improper spray of fuel because of choked injectors reduces acceleration, too.

Air Intake System - Air system issues that diminishes the acceleration are the followings -

• Clogged/ Dirty Air Filters - low airflow to the engine slows down the acceleration.
• Vacuum Leaks - unmetered flow of air into engine ruins the air - fuel mixture and impacts the acceleration.

Ignition System - The issues include the followings -

• Worn Spark Plugs - often resulting in engine misfires giving into jerking and hesitation at the time of acceleratio
• Malfunctioning ignition coil - leads to weak sparks and subsequent problems of acceleration

Sensor and Electronic Failure - This issue can lead to the following situations -

• Dirty Mass Air Flow (MAF) Sensor - leads to misreading of air intakes which makes the computer miscalculate the amount of fuel needed.
• Throttle Position Sensor (TPS) - makes jerking or sluggish response when the accelerator is pressed

Exhaust and Emission System - This issue is seen in clogged catalytic converters building up exhaust gases that chokes the engine ending up in extreme loss of power

Transmission and Mechanical Issues - These issues include the followings -

• Transmission Issues -resulting in high RPM without increase in speed because of low transmission fluid, slipping gears or delayed shifting
• Dragging Brakes - resistance from slipping brake clippers.

FAQ

What is DTC?

DTCs (Diagnostic Trouble Codes) are standardized alpha-numeric codes generated by a vehicle's OBD-II system when there is a malfunction in systems (e.g., engine, transmission, emissions) of the car. When any fault occurs, the computer, the car’s ECU, records the code for the fault and turns on the check engine light. The lights help the technicians to identify the exact problem e.g., misfires, sensor errors, emission faults, fault at fuel pressure regulator et cetera. Often technicians attach a reader to OBD - II of vehicles to read the ECU data so that they get the exact error code

What should you do if your car has an acceleration and pick up problem?

It is always better to take the car to an authorized service service center in case any fault occurs in your car. If a car has acceleration and pick-up problems then you must take the car to an authorized service center.
