'97 SL2 shakes on slowdown
1997 SL2 1.9 L manual transmission, 186000 miles
For the last several months, when I decelerate to a stop in normal traffic, frequently the engine shakes violently. This happens as the engine approaches idle speed, in or around 1100 - 1200 rpm. It happens frequently, but not every time. I went in yesterday for service, and the dealer scanned code P0341. They removed the ignition module and cleaned the coil grounds. However, that did not help. Anybody have any suggestions? Thanks, Jim |

I put the cheap ones on from carquest.. they are about $29. I'm do also.. I change them every 50k along wth tranny fluid which in my case is only 2.6 qts because I have a stick. Phil |

The problem mentioned there was a dirty EGR valve. Cleaning it seems to make some improvements in problems such as rough idle. Jim again |

I would stay with wires.. I found that my #4 wire wasn;t seated fully at the coil.. problem went away.. worse case would have been wires ($29) and cameshaft sensor ($12) Phil |
