Low manifold pressure?
Twice now, once i went to the track. The ses light came on it said low man press. Replaced map. All was good. Just got light again today, low man press. What can cause this? Ive read worn piston rings, valve guides, vac leaks..... Any help?

Okay, i did a compression test on all cylinders, they were all at 180 or a little over. So that checks out ok.
I pulled the fuel pump fuse and IGN MOD fuse for the test so the car would only crank and not try sparking/getting fuel.
Edit: car is running fine, i unplugged battery for about 15 min to clear codes and i started the car the ses light is on. Just replaced map and tps because i got codes for them today. Hopefully after a few start ups it realizes that the problem (should be) fixed.
If not ill have to get it scanned again tomorrow.

Okay another update. If i didnt mention before... I replaced the tps and map sensor again because the ses light tripped. Replaced both and did compression test, all at or slightly above 180. Started car up once all was done. Ses light was still on, unplugged battery for a bit, started it again. Still on. After a few more starts, it was gone. So guess we will find out what happens.
Also, notice i have a auto trans fuse. Pulled that tonight to see if it will help with my idle issue. Doubt it could but worth a shot. I figure i dont have an auto anymore why should i need it. Wont know till tomorrow if the car runs better without it, its raining and the car doesnt get driven in rain.  so shes stayin in the garage.

I didnt get th code from the guys at autozone. 
So far after changing the sensors and doing a comp test and few other small things the car seems pretty good atm. If it pops back up ill have to get the code.
