So I discovered a weirdo problem today whats new, im going up this hill at my college i give it gas just to get up this hill
as soon as i let off the rpms dipped all the way down and almost kills the car, i have a cel on but its telling me I have a tranny problem bad sylanoid which cant be true i just changed them, anyways the car does idle hi whne i n park after driving it for a cpl minutes, anyone got any clue as to whats going on, Low transmission fluid? bad Iac? bad tps timing? any help works thanks

P.s I just modded my car a 255hp, a fpr, boost control, cold air, and a big 16g
 
Wine could coming from the transfer case. Checked that out lately?
 
Might be a given, but did you disconnect the battery after replacing the solenoids and installing all those parts?
What did you set your base fuel pressure at (with vacuum disconnected)?

I dint really set it it seemed set but it deffiently smells rich I didnt really understand how to set it right?

I just went and adjusted it at 44 with the vaccum disconnected its running 41 with it connected should i make it higher

yeah battery was dissconected when i changed the sylanoids
 
whats a good cheap way to test soap and water seems to evaporate too quick how about seafoam?

Soapy water is the best way. You're using a compressor to pressurize the system right? Can you hear any leaks/does pressure hold on your gauge (boost gauge or on the tester)?

As for the fuel pressure that's normal, once vacuum is connected it will drop a little.
