Car is sluggish

Can an EGR valve cause it to choke up? I was going to pull the EGR tomorrow, clean out all the carbon buildup, and see if that helps.
Does anybody have any ideas what might help? Fuel filter?
Thanks in advance.

You could do a resistance test but I don't know what values correlate with what temperatures.

Where is this usually located? thanks.

When you get it off clean it out and spray it with some wd-40 and see if you get a better connection made a hell of a difference in my car

Any thoughts on the EGR? With it running I manually opened the valve and the idle stayed the same. I was going to take it off tomorrow and clean it and the inlet port.
Thanks for your time. I just don't want to throw parts at it. Although that's hard to do without diagnostic tools.

It stands for Oxygen Exhaust Gas Recirculation Valve. I don't however think it can make that much of a difference.
Exhaust Oxygen Sensor (commonly called O2 sensor) is probably more responsible, and I think should be a part of a tune up. It screws into the exhaust near the catalytic converter. You have to raise the car to replace it. 7/8" deep socket is what you need, maybe Power PB blaster if it won't come off easily.
In your specific case, I don't know. Probably some sensor like said above, or a thermostat? T-stats do go lazy. But, it could be that you have two different problems - one with temperature and the other with acceleration. It seems doubtful to me that it not getting warmed up can cause performance problems. But maybe I am wrong. Maybe the ECM thinks it is always in cold mode. Do you run rich also? I.e. Poor MPG?

It does't run rich, at least I'm not smelling any gas. It'll take a couple times to start her up (especially since it's started to snow). But once it does it idles at 500 rpm and then after 3 minutes or so begin to rise. It stays at 1k rpm until I give it some gas. It will cut out or just chug real bad until the needle is on the half way mark (on the dash). Once it's warmed up, it's totally different.
I'll lift it up today and pull the o2 sensor and clean the egr. In the meantime I love hearing all your thoughts so keep 'rm coming int! Thanks for your time.:-)

Pulled EGR and the inlet port was completely clogged. Scrapped that out and cleaned the EGR too. Ran the car without EGR for a few minutes to blow out chunks of buildup in inlet. Then I put the EGR on. It sounded much smoother, very quiet, but the hesitatin was still there.
Now when I opened the EGR all the way during idle it did nothing, nada, zip. I thought it should stall out the car? Hardly a change in idle. I ran over to my Toyota and did the same thing and the engine died. Should I run to the junkyard and pull a new EGR out and see what happens?
Also, something I forgot to mention. I can haul a** in reverse and it won't chug at all. Pop the clutch and whippy! I'm moving backwards no problem.
Any further thoughts? I'd love to hear what you think.
I just got back and I can not find the o2 sensor on this car, where do the hide the thing? On most cars I can find it in 30 seconds...

This doesn't sound like an EGR problem to me. I'd check your timing and basic tuneup stuff first. The reverse thing you mentioned kind of sounds a little like the float setting in the carb could be off, but that's mostly speculation.
