im been having some weird problems with me 1997 vw gti 2.0 lately. its been doing a rough idle at almost every time i stop with or without the a/c on. sometimes its dipped as low as 500 rpm but it usually hovers around 800. today i was just sitting at a stop light and the revs dipped to around 200 rpm and then it stalled out. started it back up and it was fine. now....i know this is covered under vw certified or at least it should be but does anybody have an idea of what could be causing this? spark plugs wires fuel filter etc? i wanted to replace the plugs but they look like a bitch to get to. dave you seem to be the expert on 2.0 engines any ideas?

thanks in advance guys

 

how would i go about removing the spark plugs...i was reading around i some people said that they needed a tool to get at the plug wires to remove them. also how could i check for vacuum leaks?

 

turn the car on pop the hood and see if you can hear air excaping and find out where its coming from...
