I have a 92 stealth es non turbo automatic. Recently, the transmission went out and i did a tranny swap(possible valve body failure). I cleaned out all the electrical plugs, dielectric greased them, blew out the cooler ect. The tranny shifts great but im having other problems. The car hesitates when put in reverse or drive like its lacking power and have to put the pedal to the floor for about 10 seconds before it starts to move. When the car gets to opperating temperture and is put into a gear, the rpms drop down way low and often shuts the car off. I also checked the vacuum lines and found that all the lines except for the pcv valve are dead. I changed the spark plugs, cleaned the mas sensor and plug and is still acting up. Im thinking the egr valve isnt functioning. Does someone have an idea what the problem could possibly be.PLEASEEEEEE HELP thanks
