| Post subject: | Check Engine light BLINKING, Help! |
About a week ago my 2006 Liberty Limited started vibrating/shaking/rumbling violently but only at idle like at a red light or stop sign. It has 75K plus miles but has had regular maintenance for the 35K miles I've owned it. As previously mentioned the problem occurs when waiting at a red light or at what I assume to be only occurring at low RPM's. Im sure it's the engine doing all the rocking, it's almost painful to sit inside when this is happening. When I start to accelerate the problem goes away and so does the light after driving a few hundred feet. This issue happens when I'm sitting still in Park, Drive, Reverse and Neutral. Haven't tried it in 2 or 1. The accelerator, throttle and/or gas pedal is unresponsive unless I slam it to the floor. Like I said though, I have done regular maintenance every 4-5K miles. I was having this issue about about a month ago and promptly took lady liberty to the stealership and the "problem" was something misfiring that cost me $300 to fix. Now it feels like it has the same symptoms that $300 was supposed to have fixed. What do I do? |

A blinking CEL is a sign to stop the motor no matter what as damage will occur. It usually signals a very bad misfire. When did you change the spark plugs, which type, and what codes are set? |

Spark plugs were changed by the dealer 7,000 miles ago. Codes are: P0300. Engine misfire P0152. Electrical/Battery bank Why are these happening? |
