acceleration

Hey all- my 2003 protege 5MT has thunk/shudder when accelerating from standstill from the front driver's side. I just replaced 3 motor/trans mounts (front by radiator, driver wheel, passenger wheel). The thunk/shudder I am getting when accelerating from a standstill/releasing clutch has...

My 2014 CX5 2.2l TDI Akera randomly fails to accelerate past 100kph - very unnerving when going to pass a road train and it randomly decides it's not going to happen and sometimes I will have to pull out of the passing manoeuvre. It acts like a speed limited truck - gets to 100kph and locks at...

Been having this thing where the engine gets extra "loud" during medium to heavier acceleration. It sounds almost like an old carburated engine when you let it rip, whereas before it was more like a sewing machine revving up :) no discernible growl or rattling/sucking . It's coming what sounds...

i have a problem accelerating with my Mazda3. After it warms up this problem emerges when that If I slowly edged the car up, it will run like normal. however, when I stomp the gas petal, the car just doesn't go. it chugs, it backfires, but it just won't accelerate. it works for for the first two...

I've looked around to see if anyone else has experienced this, but there don't appear to be any postings. I've had my 2014 GT AWD CX-5 since April. Everything was going well with the vehicle for the first 5000 miles. My wife and I were about to drive from Seattle to Ann Arbor (moving...

My 2002 Protege5 is no longer able to easily make it up even the slightest of hills. It doesn't miss, nor generate an error message, just slows forcing a downshift. I'm the original owner, and it has 75K miles. It's a 5-speed. The problem started after I tried platinum plugs. I switched back to...

Hi, I bought a new 2012 GT 3 weeks back. Lately,I've noticed few things. 1. There's mild vibration/rumble on acceleration on the lower gears. Its seems to be pretty consistent now. 2. There's a foul odour everytime I turn off and turn on the AC. It's similar to one where the AC filter needs...

I have an 02 Protege ES 4-cyl 2.0L. What are some relatively easy/simple/possibly cheap ways to tweak/tune my engine to gain more hp/accelaration/torque? And I don't necessarily mean boreing/oversized cams/intake/exhaust. I mean like simple secrets I guess. Any tip is appreciated, thanks

Inspired by the book "Fast Car Physics" by Chuck Edmondson, and being a physicist and MSP3 2007 owner, I decided to do my own calculations of Acceleration Vs Speed, to determine the shift points. I used published Hypertech (which I have on my car) HP and Torque dyno data and the available data...

hey can anyone help my car runs fine in ever way except when am in low acceleration under 2500 rmp when the pedal is pushed all the way down it studiers until i go over 2500 rmp then acceleration is fine.

I traded my '07 Mazda5 Touring for a 2010 Mazda5 Touring back in April and have noticed in the 2010 a serious lack of cajones when I want it to get up and go compared to the 2007. The engine and dimension specs appear to be exactly the same. Anyone notice acceleration problems in 2010 Mazda5...

Hey guys. i have a prblem.... out of the sudden after a tune up and a waterpump/timing belt change...my RPS are going crazy... first let me tell you that my timing its "on" its place, i had it inspected by two mechs....here is the problem: whe driving, and all of the sudden the light turns red...

I just purchased a used 2008 CX7 with 16,000 miles. I've had a loaner one for the past two days. Today when I picked up the one I was purchasing, I noticed a little different engine noise when I accelerated. It's difficult to describe, but it sounds kinda like a diesel engine rattle at lower...
