Ok guys '95 Trooper 3.2 Sohc 195,000 miles

Its obvious that I have a fuel mixture problem. I'm not getting any check engine lights or services codes. So where do you think I start. EGR, MAF, PCV, Cat, bad injector, etc...

Of course I'm trying not to replace all components so which do you think is the most likely.

Thanks Mark
