Shakes or Wobbles problem
2004 Pontiac GTO V8 Two Wheel Drive Automatic 60000 miles
I have custom Long tube headers with catless mid pipes and flowmaster mufflers for my exhaust. I've noticed that when my car is at idle and in drive I get this pulse like intermittent vibration underneath my car. The only codes I'm pulling are 02 sensor codes. My front 02's aren't plugged in because I need adapters due to the stock wiring not being long enough. That explains the codes coming up but can that explain the vibrations under the car? I know what 02 sensors do and but I didn't think they'd cause shaking. My only other question is could there be rubbing somewhere? There are NO leaks double triple checked that. Maybe bad spark plugs? What could cause this vibration? It's only on idle worse in drive some in park. Nothing when I'm actually driving. My RPM seems to drop some to when I put it in gear and idle. Also gets worse when my A/C is on too. Any advice would help. I already ordered the adapters for the 02 I'm just wondering if I shouldn't even be driving my car.
have the same problem?
