Welcome to the forum. First, it may be interesting to read post #3 here:
With regard to the EGR code, not only does the EGR valve need to be cleaned but often the passages, as well. If you have the mechanical EGR valve, when you engine is warmed up, push the diaphragm of the EGR forward (without burning your fingers or puncturing the valve!). Your engine should try to stall. If it doesnít, it means that the passages themselves are clogged. If you take the valve off the car, you can use carb cleaner sprayed into the intake and exhaust passages that you see, and ream them out as best you can. Before putting the valve back on the car, start the car for about 2 seconds. The engine will rev VERY high, and hopefully blow out some carbon for you. Note that you may have to clean the valve and passages a number of times before the code goes away.
For the TPS, that circuit is more than just the TPS sensor, but is also the wiring, connector, etc. And even a new TPS sensor needs to be calibrated. Chances are you probably didnít need a new TPS, but would either have to re-calibrate the idle switch in the TPS, or check the wiring, resistance, etc. The entire FSM for your car is over on Acks FAQS:
If you go to section 6A (mechanical), youíll find instructions how to test and calibrate the TPS system in your car.
