My 2000 gran prix 3800 v6
stalls out, I can restart it when I clean my pcv valve and unhook the map sensor, and even then it will only idle untill I put it in gear then it stalls. What do I need to replace.

Clean out the idle air control and the EGR valve and test the throttle position sensor If the check engine light is on, have the computer scanned. If it isn't check for major vacuum leaks, check the maf sensor. Without the check engine light being on, it becomes a guessing game. Also, check fuel pump pressure. Directions are listed on our homepage under the DIY section. Let me know
