hey ive got a 92 regal with a 3.1 engine that will start sometimes and sometime it wont. ive changed plugs and wires, ign module, ecm, tps,ips,and gas filter and fuel pump checked ok. also changed map senser 3 times and it still gets 33 code and not idling correctly. i need help from someone who has fixed this problem already. also checked all vacuum lines with no leaks.

Disconnect ther vacuum hose from the map and check with a vacuum gage, engine running, should be about 18" hg, do this quickly as the engine will try to load up with the hose off.
