Living in the Netherlands, smog equipment on older cars is not so big an issue as in the US. Question is: can i simply remove all Air equipment and plug the holes in the headers, or will i end up with SES codes and lights.
Please help

You can remove it, no problem. No codes. In fact, I recommend it.
bczee and vinnies87, my car is a 86 convertible, with the 5.7 TPI. Exterior and interior like new, but has not received maintenance for the last 4-5 years, resulting in a lot of mishap with faulty electrical contacts and an automatic gearbox with a non operating overdrive
I have not look at the FSM, but I think as stated before, it can be removed.
As far as the problems you are having.. Yes this can happen if maintenance is overlooked as well as just normal degrading parts. I can only suggest you start catching up with all of the maintenance. Get a can of electrical cleaner and de-connect all of the connector and clean and reseat them. You also might look into replacing key sensors and switches. (are you getting any codes ?)
You should flush all of the oil and system (cooling, engine oil and trans oil).
When I picked up my 88'... It was most likely like your.. not very well maintained and he didn't fully understand the system (electrical, ECM, Sensors). I was throwing about 4-6 codes.
I spend 10-15 hours chasing down bad vacuum line and dirty connector. Replace the O2, ECT, some relays, clean the MAF and intake, Rebuilt the Throttle Body..Complete tune up, Seafoaming the engine,well. let just say that after doing all of the work.. it passed the Calif Smog test with number that I thought was of a much new and lower mileage car and now run very well for a car with 148k on it.
If your car is running poorly, it might be better to find out why. Removing parts might make it worse or make it more difficult to rule out other things. Air is directed to the headers at startup to help light off the O2. If you feel the air pump is causing something, clamp off the hoses to the headers. If that cures whatever the problem is, then you can fix it - even remove it - though if you do remove it, you might consider a heated O2.
bczee, thanks for the advice. At this moment i have a code 36, Maf sensor burnoff issue. The car is not a daily driver, and complete maintenance is scheduled in the near future. Planning to remove and flush fuel injectors, replace gaskets, oil in trans, engine and diff, clean a lot of things and so on.
SunCr, already done so, gave no result, however the heated O2 sensor is good advice. Will install this, because engine will run quicker in closed loop.
I am not sure how common, but from what I have read.. yes, you should replace the MAF Relays if cleaning and checking of the wiring doesn't resolve the lated codes. I did fix my MAF Related problems (along with the Cleaning of the MAF and connections).
All 1996+ all they do is hook up a cable to the OBD II port and nothing else. They just start the car and the smog machine does the rest. To tail pipe, no reving nothing. I saw this today whan i got my escort smogged 1993 had to be revved ect. Check engine light was on So I pulled the fuse for all dash functions passed with flying colors.
