Found out this problem, but...
Okay, the problem can be explained in this thread
https://www.rx7club.com/2nd-generation-specific-1986-1992-17/what-deuce-could-429235/
It turned out to be the little solenoid under the throttle linkage that has something to do with the A/C. Well, the little plunger dealyjobber was getting stuck and not allowing me to rev past about 3500rpms. I sprayed some WD-40 on the plunger shaft and it helped for a while, but its acting up again. My question is- where can I get a new one of these? If anyone happens to have NO i-clue what the hell I'm talking about, provide me with an engine bay pic of a stock S5 and I'll circle it in paint. Thanks.

Okay, I've figured out what it is, I think. Its either the Narrow Range Throttle Sensor, or the Full Range Throttle Sensor. The only problem is that I can't find anyone that carries it and its becoming a neusance. Please help.

TPS sensors are commonly found on ebay and the for sale section.
I would double check that it is adjusted correctly after replacing yours.
You would want to avoid using any wet lubricant (like the spearm of the devil called WD-40) on the TPS, as wet lubricants tend to go places that you don't want them and then attract dust and dirt further jamming and damaging the part. In addition WD-40 has solvents in it that tend to eat teflon and other plastics weakening them further. So by spraying that on the TPS you pretty much killed it if it was not already dead. WD-40 should never be used in cars, but rather for rusty loud door hinges at your home.

Well, the TPS is another problem altogether. Whats causing the "3k rev-limit" is either the Full Range Throttle Sensor, or the Narrow Range Throttle Sensor. I just can't seem to find one, and junkyards are out of the question in this town.

Yeah , $140 is a heck of a deal. I just replaced mine for $200 for victoria british. I see no sense in spending 60-80 dollars on a another 15 year old electrical sensor. Why not just pay the money for a new one? Any other type part that can be inspected visually is a different story, I just don't like the idea of paying a significant amount of money for an electrical part from a junkyard or similar source.

I did, and yes I have a 4, there are differences, but there are more similarities. You certainly won't damage anything with just the narrow range unplugged anyway. Might have to increase the idle at the throttle body, (if it drops below 750) which you should do anyway for a better running vehicle.

if i unplug my tps, the car WONT rev past 3k period
advance auto quoted me a new tps for my car for like $130
not sure if that was with the managers hook up or not, but its cheap non the less ... considering the dealership wants like 400 or more
