    Just picked up an 2005 gt, currently has 34k miles and appears to be well kept. recently starting having a loud grind/knock on cold start that last about 2-3 seconds. Car runs strong and does not seem to lack any power. Had someone listen and was told it was slapping from the timing chain(...

    Alright, this is my first post here so if I'm doing anything wrong, let me know. 2000 Mustang V6 with stock 4-speed automatic transmission. The short version of the issue is that I'm hearing a metallic knocking sound coming from the front half of my car, there is no check engine light, and...

    I've been hearing a pinging or some kind of knocking noise from my engine for a while now. It happens intermittently, usually when I'm idling at a stoplight or something. I never hear it with my foot on the gas. Here's a link to a video of what it sounds like: Listen for the noise at 0:18...
  4. 2011 - 2014 Mustang GT Tech
    Hello everyone, I just recently purchased an early build 2011 Mustang GT, 6MT. I have been experiencing what I thought was an exhaust leak, at least it sounded similar with the window down. The car still has a couple of months left on the power-train warranty and of course when I take it in a...

    Hello everyone, About a few weeks ago i noticed that when I drive my car for say 30 or so mins, then i turn it off, there is a slight "knock" every 15 or so seconds for about 2 or 3 mins. I cant tell if its coming from the motor or somewhere towards the dash in the engine bay. I have Intake, 93...

  8. 2.3L Tech
    So I have heard recently heard of something called a Knock Sensor on the 2.3L engines. I also heard that they hamper performance significantly. What is a knock sensor and what does it do? Does it really decrease performance? If so can it me removed without many/any negative effects? Where is it...

    Hello all, I have an interesting situation. Just rebuilt a 302 and I dropped it in to start it. Initial timing was at about 8 deg BTDC. So when I attempt to start it it runs rough an only runs when I keep giving it gas. It dies when it drops to idle. That I attributed to timing or perhaps some...

    So for about a month or so I've had a really irritating engine squeak, at first I thought it must be the belt, so i replaced it, but it didn't fix anything, I've started the engine with no belt and the squeaking still remains, the squeeking is worse when the engine hasn't been started for a...
  11. 2005-2010 Mustang GT Tech
    I have a very loud engine knock.. To get to the point, I was going through the gears shifting at around 3000 RPM and I got to 5th and I had a REALLY bad misfire.. The car fell on its face and was losing acceleration rapidly. So I started to pull over and a LOUD clicking noise came into play. The...

    Hello all, Today, after changing the oil through Jiffy Lube, I began noticing a knock/rattle in the bottom of the engine that I haven't heard until its oil change. The first obvious thing I did was check to see if they actually put oil in it and a filter on it and its good and full. I recorded a...

    I have a 2000 GT with 162k miles and a manual transmission. I have been getting a knock or tick sound when I accelerate. I was finally able to capture the sound with good audio and upload to youtube. I am not sure what the sound is, but it is very annoying. It does it when its cold or hot (more...

    I currently drive an 01 mustang v6 5 speed. We had the throwout bearing and pilot bearing, and a steel bearing retainer put in but after the job was done, the clutch pedal gradually developed a strange knocking sound. I know the throwout bearing will knock when it is warn, but this is not the...

I have checked to make sure everything is tight, I even had an...
