Spark plugs fouled from running rich.
After fire happening in the exhaust ahead of the cat.

Check your oxygen sensor signal.
Check your water temp (ECT) to the ECU.
Put clean plugs in it.
Test fuel pressure.
​​​​​​Test fuel volume coming out of the regulator.
Test ignition spark voltage.

Probably some other stuff, but it's late. That will give you some research and homework questions...

Well everyone I believe I found my issue, really pissed off with myself because this is where I started troubleshooting in the first place. Started all over from the beginning today and saw it immediately after pulling the valve cover figured I would share in case anyone ever has a similar problem. Thanks for the help everyone!

Yuck. Which valve does that lobe (not) open?
what are you going to do now?
This reminds me to start running Camshield additive in my 22re as I do in my 327 Camaro.

it was the 3rd lobe from the front. I have a spare (stock) camshaft from a previous rebuild I did not to long ago, going to put it in tomorrow and let you all know how it runs. Any idea what would cause this? the rocker arm pads appear to be in good shape

Where did the cam come from?

Are you going to gamble, and not change the head gasket?

Ya being that I only pulled the headbolts and not the actual head i believe everything will be okay. I'm planning on doing a rebuild in the near future just really need this vehicle throughout the winter time. As for the cam no idea where it came from the person I bought the truck from said he did a rebuild on it and everything is new however as I dig more into the motor it looks to me like they had no idea what the hell they were doing

Good luck, but the odds are against you. I tried it once on a 20R and it worked for about 250 miles.
I wouldn't worry about the used cam if it looks good and you have the rockers that were with it.

Show a photo of the cam follower / rocker pad also please.

Bad cam, bad cam break-in, bad rocker pad, improper oiling (doughnuts, off axis driving, exceeding oil life span, oil bypassing oil filter), debris, over tight valve clearances, no zinc additives.. Probably some other stuff I'm neglectful to mention.

WOW! well darn. At least you got it figured out. Iv'e seen a few similar to that. Both as I remember were rigs that the owners let oil changes go too long. One was a guy I worked for building houses. He would load his two wheel drive 22re down with 2 x 12's for concrete forms and drive up in the mountains. He did this once a week at least and would change his oil every year or so.. LOL. The motor finally gave out after 300,000miles. Be hard to find a motor that would put up with that kind of abuse for that long. I pulled his motor and head and found a similar issue to yours.
