2004 Cadillac Deville Base feels like it's missing when I stop at the red light
Hi,
I have been having a hard time figuring it out why my car feels like it's
misfiring when I start first thing in the morning and start driving. It runs
really good on the highway I am getting almost 24 MPG on highway. I
changed the spark plugs, TPS Sensor and run Full Synthetic Oil. I had a
lean condition last year which I fixed by changing the Mass Flow Air sensor
and finally I had to replace my catalytic converter and O2 Sensors. I have
190k on it but still runs very smooth. This problems goes away after driving
for a while when engine reaches it's temperature. Also I do not have any
codes popping on the dashboard. I was planning to change the ignition
coils but would like some opinion. I have shown it to few mechanics and it is
very hard to replicate the problem. Any suggestions or if anyone had a
similar issue.
