Hi guys, I've been lurking the forum for several years since I got my car in '05 and have recently been contributing a little more.
Lately, I began noticing a rough idle problem with my '02 Golf TDI Automatic, when I put the car into Park from gear, i.e. go from D->N->R->P. Basically, as soon as I get it into park from reverse, the RPMs just suddenly drop to 860-863, according to my ScanGauge, about 40-45 RPMs below normal idle which is 901-904. The problem is intermittent, but it's been happening more and more, mostly when the car is warmed up. Once it happens once during a trip, if I put it back into reverse then to park immediately after it happens the first time, it will almost always happen again. But if I just go and keep driving around and then park, it will only happen randomly.
However the engine doesn't just drop rpms, it also sounds very strange. I don't know how else to describe it, but it chugs really hard and slowly, almost like its going to cut out altogether. What other parameter should I be looking for on my ScanGauge to find out what this is? I had a Vag-COM but it was an old serial one that wouldn't work with my Mac and I returned to get a USB one, so I should have one shortly for more diagnosis.
The latest mod that I have is the EVRY mod with a 1k ohm resistor between pins 2 and 3 on the fuel pump harness. The thread on how to do the EVRY mod said that if you go low enough in resistance it will comprimise the idle. I didn't have this problem before, when I first installed it, but the resistor is going to be the first thing to come out. I don't know what else I should try. My other mods are listed in my sig. Please help.
