Well, I guess things were going to good. Something just had to happen..
I searched for hours on here both via the built-in search and by using google, but to no avail. There are also way too many useless topic titles such as "omg help please."
It's a 2003 V8, with zero previous issues (according to OASIS).
I did 4000rpm in 2nd gear on wednesday, going up hill. The car felt very unusual afterward. I almost thought I had busted something.
As I stopped at a red light, I felt a fairly strong shake/stutter/vibration as if it were transferred from the back to the front of the car. RPM dropped from the usual 750-800 by about 100-200. This repeated itself 2 or 3 times at irregular intervals. Might I also add, I believe this does not happen when in P or N, only when in gear, but I don't want to spend 20 min each to really find out. The problem is also intermittent - it doesn't always happen when I'm stopped.
I immediately visually inspected the car when I got home. Zero leaks, nothing seems broken, but I am no mechanic. There is also no CEL.
On thursday it happened again, but to a much lesser magnitude. The vibrations seem to be much smaller now. I pulled the MAF, cleaned it, reset the battery and I let the car idle for about 20 min. Went for a ride, all seemed OK apart from how unusual the car felt. The car now idles at around 650-700 RPM.
Yesterday the vibration occurred about 2 or 3 times on my way from work, again only when stopped. Coincidence has it that just as I was letting go off the brake when a green light came on, it happened again, but stopped as soon as I let go off the brake pedal. Hmm..
Turning the A/C, stereo, etc. off also does not seem to make a difference.
The car is regularly maintained. Oil + filter change every 5k km.
I am thinking it's perhaps some idle control, or a sensor of some sort. Perhaps even an injector problem?
On a seemingly unrelated note, since a while back, I've been having a similar stutter/RPM drop only when on cruise control doing 60km/h (37mph). The RPM would drop by about 500. Again, this didn't always happen. The only times it did, was at work (military base), at that exact speed.
ATM, the car is at the dealer getting diagnosed. They will take it for a spin as there's no CEL, and said there might not be any codes. I am hoping it's a coil so that they fix it for free.
Any ideas/suggestions are welcome and much appreciated.
