  1. Check engine light flash while on track. Road america

    I had the P0300 code. My situation was different (not on track, just street driving) but what happened to you sounds like exactly what happened to me. Light came on, it flashed for like 5 seconds and turned off. I didn't know if the car was good or not because it felt fine afterwards. Bought an...
  2. Had the Check Engine Service Soon light flash for 4 seconds and then go away. Is my engine okay?

    Okay. I'm not that well with cars so I really honestly wouldn't know where to start. I just read what the potential issues are for a Mustang with the code but I don't have the means to diagnose it. So I'm guessing it would be risky to drive it to the dealership? The one that I trust is out of...
  3. Had the Check Engine Service Soon light flash for 4 seconds and then go away. Is my engine okay?

    Just got the code looked and its showing PO300: random misfire detected So my car is not good. I'm guessing this is bad? I just did a Google search and apparently this is an issue with intake manifolds and misfiring. There are posts on here about it. I guess it's good to see that others...
  4. Had the Check Engine Service Soon light flash for 4 seconds and then go away. Is my engine okay?

    Thanks, so it looks like the theory of the engine coolant is useless. When I was googling the issue I saw a post on another site that mentioned that it was the catalytic converter. Was hoping that this wouldn't be the case. Is there anyway to confirm that my cats are fucked? I was going to...
  5. Had the Check Engine Service Soon light flash for 4 seconds and then go away. Is my engine okay?

    I don't remember exactly, but I don't think I ever saw the oil temps go past 243. I will say that I don't remember ever having to ease off or worrying about temps getting too high before and now that you mention it, I have noticed that the oil temps now are usually higher than before The wrong...
  6. Had the Check Engine Service Soon light flash for 4 seconds and then go away. Is my engine okay?

    Thank you for your response :) I didn't look at the oil pressure, the oil levels should be fine, I just did an oil change (500 miles ago) , If it burned through 10 quarts it would have been noticeable (I think) the engine is hot right now so I will check once its cooled now Just checked the...
  7. Had the Check Engine Service Soon light flash for 4 seconds and then go away. Is my engine okay?

    I was out driving today and I saw the yellow check engine service soon light come on today on my way back to my house. When I saw the light I first that my engine was dead but I didn't hear any weird noises or metallic clunk everything was normal. I saw that the Oil temperature was 250F degrees...

  9. Is subtle rattling at low RPMs normal after resonator delete?

  10. Is subtle rattling at low RPMs normal after resonator delete?

    Okay thanks when I looked at it it seemed okay
  11. Is subtle rattling at low RPMs normal after resonator delete?

    I am okay with the interior rattle, but it is definitely coming from something underneath the car. It sounds as if something underneath comes loose and scrapes the ground. When I rolled down the windows, I could hear a metallic click, definitely something from underneath and not inside. It...
  12. Is subtle rattling at low RPMs normal after resonator delete?

    Okay thanks, I was going to do that after I got back but the exhaust was still hot, didn't want to burn myself. I'll make sure to checkout the clamp. I do believe that it is a simple adjustment, because I didn't see anything out of the ordinary when I took a peak. If I cant figure it out, i'll...
  13. Is subtle rattling at low RPMs normal after resonator delete?

    Hi guys I have a 2020 GT350 and recently got the LTH resonators for it. I had it installed yesterday, I wanted to make it sound just like the GT350R. I Iove the sound its great however when I went for a drive today, I noticed that as I was coming to a stop at around 1k - 2k rpms I hear a...
