Hi, I've been having trouble with my 2000 GT having rough idle and feeling sluggish for awhile now. I've gone through many different things to try to figure it out: replaced spark plugs, fuel filter, PCV, checked for vacuum leaks, installed K&N CAI, cleaned the MAF, cleaned the IAC, used fuel injector cleaner, etc, etc. Most recently, I took the EGR valve off and checked it out - from what I could tell it mechanically seemed to be working properly. It was sealing well, the valve would open if vacuum was applied, so I put it back on and next time I went for a drive, my idle problem was gone and my car felt more powerful. Problem is - I forgot to put the vacuum hose back on to the valve. Once I put it back on the problem was back! I have a Haynes manual and went through some checks of the rest of the EGR system and didn't find any problems.
Any body have an idea what is going on??
