The other day on my way to work and hit a patch of black ice. My car revved to red line and after I caught traction my car hasn't driven the same.
My car now sounds different than it did before. The exhaust note sounds like its now more muffled, almost like a car sounds when its misfiring. My car is now lacking power throughout the power band. My car also makes a noticeable ticking noise upon cold start, didn't do that before. One last symptom that I have now noticed is that at random, upon deceleration, my cars RPMs will randomly spike up to about 1000RPMs and then drop back down again.
I don't think it could be misfiring because through experience I know that the car would have much less power. The power loss here is only just noticeable.
I do think it could either be that something happened to my timing belt tensioner or the timing belt itself has stretched.
I have also noticed a vacuum leak sound coming from around my BOV. I am thinking about putting a stock BPV back on to see if it takes care of anything when I can find another one, but I cant find the source of this sound.
If anyone can please offer me any information I would greatly appreciate your time and your help. I'm getting pretty depressed, I just want my old car back and to catch this before it turns into a bigger problem. Thanks in advance.
