MIke D Posted March 26, 2008 Report Share Posted March 26, 2008 I had an intermittent skip that over the last week has become a more "constant" skip. on a few hard accelerations it coughed back through the intake. after searching here and seeing that my intake was loaded up with carbon a few months back (starter work) I tried a TEC. Now the more constant skip is a steady misfire. I mean one or more of my cylinders are not working. What was a po300 in the history every once in a while is now a flashing DIC and even when cleared comes right back. on WOT it's like I'm running on 6... What's our next thought... History: new plugs 20k ago new wires 10k ago this started happening when it warmed up.. I.E. in the 40's on up. it does not matter whether the car is warm or cold. I was originally leaning to a bad ignition pack but why would TEC make it worse so does it mean it really is carbon? Thanks in advance MD Cop didn't see it, I didn't do it! 93 STS 225,000 Miles 99 STS 111,000 Miles Link to comment Share on other sites More sharing options...
