I have been having this intermittent problem for several months, and have not been able to get to the bottom of it:
The RPM gauge will dip and jump around, sometimes almost like a seismograph would during an earthquake. Sometimes it will completely go to zero, like its dead. Then a few seconds later it will jump up alive again.
If I am driving, this RPM fluctuation can coincide with very slight lurching in the engine, much like an automatic transmission shifting. The problem can be either non existent, or sometimes severe to where I feel like the engine might die.
Sometimes the check engine light can come on, and I just took it in and my mechanic says now its the ignition coil (or so the computer tells him, he's not a very good mechanic). Could this be the problem?
Any idea what this could be? :-)
have the same problem?
