Matt Posted February 23, 2005 Report Share Posted February 23, 2005 Hi Guys, I want to thank you all again for the tips. Today I refreshed my cooling system just the way I was told to do it. After all the great help I decided to do it today, I'm glad I did. I also cleaned out the throttle body and EGR delivery tubes the way I was told to do it. I bought pipe cleaning rods and a couple of tooth brushes and went to town on it all. I then did the PCM reset. The idle wile in drive is only a little bit better, it is still on the rough side. The RPM drops off and the engine bumps around a bit. When it is in park or netural the idle is perfect and smooth. Why is it rough in drive ?? So what do I check next to see why it's rough in drive? When crusing along on the hi way , weather at 35 or 65 MPH for the most part it's pretty good. Only once in a wile can I sence it being a little rough for only a couple of seconds. If I boot it a little it clears right up. Could there be something up with the plug wires or cap? They look good and I'm not sure if they are the original wires. The cap looks to good to be original, I hope it was changed by who had the car before me. Bare in mind Im about half way through a tank of Mobil Hi Test and a bottle of fuel injector cleaner. Going to sleep now, cant wait for the ride in to work in the AM. Good Night all. Matt Link to comment Share on other sites More sharing options...
